MACK SPECIAL PURPOSE TRIMS MACK ACV valves are available with special trims for critical service applications.

Existing Mack ACV’s can be retrofitted with alternative trims without removing the valve from the line.

‘V’ PORT TRIM

Mack Valves ‘V’ port trim is a precision engineering trim designed to alter the ratio of flow to valve lift. The effect of this is to give greater control particularly at the low end thus enabling the valve to control over a much wider flow range and in certain cases eliminating the requirement for a second smaller valve installed in a by-pass application to cater for low flow conditions.

ANTI-CAVITATION TRIM

Mack Valves anti-cavitation trim is designed for use where the valve is operating within the cavitation zone (refer cavitation chart). Valves working in the cavitation zone are susceptible to severe damage, excessive noise and vibration. Mack Valves anti-cavitation trim consists of a pair of high precision double sliding cages manufactured in Grade 316 stainless steel with proportioned orifices to enable a high degree of flow control. These cages control the point at which the cavitation recovery occurs and allow it to dissipate harmlessly.

Contact your nearest Mack Valves outlet for help in selecting the correct trim for your application.

MACK PRESSURE SUSTAINING & CHECK VALVE


Maintains a constant backpressure by relieving excess pressure downstream.

Positively prevents return flow when pressure reverses.

The valve modulates to maintain a constant inlet pressure.

If the pressure reverses, the valve closes.

Automatic operation assures pressure setting can be changed easily.

Prevents excess demands in the lower zone from drawing down the pressure in the upper zone below the valve set point.

Prevent over-pumping and pump cavitation due to excessive downstream demands causing an

unacceptable low-pressure zone at the outlet point of pump.

MACK PUMP CONTROL VALVE

Model No. 13112A-36

13112A-36 Typical Function & Application

The pump starts against a closed valve.

Regulates both the opening and closing rate.

The valve begins to open slowly, gradually increasing line pressure to full pumping head.

Self-cleaning strainers always ensure that the pilot control is always kept clean.

Prevents reverse flow regardless of solenoid or diaphragm assembly position.

13112A-37 Deep Well Pump Type

Eliminate pipeline surges caused by the starting and stopping of deep well pumps.

The pump is started and stopped with the valve in the open position.

The pilot control system includes a limit switch assembly, which acts as an electrical control between the valve and the pump.

Features

Valve does not need an outside pressure supply and relies on line pressure for operation.

The rate of opening and closing can be adjusted separately.

Solenoid valves have manual override.

Does not rely on an external packing gland for sealing purposes. Typical Installation Gate Valve

Typical Function

The valve will remain wide open when the inlet pressure is greater than the outlet pressure.

When a reversal of pressure occurs, control tubing from the outlet side conveys pressure to the top of the diaphragm, forcing the valve to close.

Optional opening and closing speed controls on the pilot tubing assist in surge prevention.

MACK PRESSURE REDUCING VALVE

Valve Selection Select a valve of a size suitable for the expected flow

and required pressure loss. Incorrect sizing of valves

can produce problems. Before selecting a valve,

consider initial pressure, reduced pressure, and

maximum and minimum flow rates.

Excess velocities considerably shorten the life of any

valve.

Stainless steel trim should be specified if high velocities

are expected. If inlet and outlet pressures on cavitation

chart are within the cavitation zone, valve requires the

use of Mack Valves anti-cavitation trim.

The Pilot Control Valve senses the downstream pressure in the main valve and allows flow to occur when the downstream pressure is lower than the spring setting on the pilot valve.

When the downstream pressure is higher than the spring setting on the Pilot Control Valve, both the pilot control

and main valve close.

The Pilot Control Valve reduces pressure from main and keeps pressure constant, regardless of intermittent demand.

The 13112A-18 Valve maintains an accurate downstream pressure regardless of fluctuations in the inlet

pressure of the valve.

The valve maintains an accurate downstream pressure regardless of fluctuating demand or variations in inlet pressure.

The valves prevents a reverse flow through the

main valve should the downstream pressure exceed the upstream pressure.

The valve positively prevents a backflow

occurring should the down stream pressure increase above the set point.

The valve closes slowly on pump shutdown.

Careful selection of the size of the valve is

paramount as excessive velocities considerably shorten the life of any valve. Stainless steel trim if high velocities are expected.

MACK FLOAT CONTROL VALVE


The Mack 407 Series Float Control Pilot Valve consists of a multi port rotary valve connected to a float, which travels vertically on a float rod. Adjustable stops are located on the float rod.

The main valve remains closed until the

float reaches the lower stop, which positions the rotary valve to open the main valve.

The level in the reservoir can be allowed to

drop to any desired point from .1 below top water level to 4 metres below TWL.

Line pressure must be minimum 7 metres

head for correct positive operation.

OPERATION ♦ Automatically controls the height of the top

water level with a one-way or two-way flow through the main valve.

♦ Designed to control the high water level in

reservoirs. ♦ The action of a three-way diaphragm

actuated pilot valve opens the main valve to allow the reservoir to fill or close it when the reservoir water level reaches the top water level. The valves are non-throttling and remain fully open until the reservoir reaches full capacity.

Additional Special Features

Back pressure (sustaining) feature Retains a minimum pressure in the supply

line and fills the reservoir only when the designated pressure is exceeded.

Rate of flow control Limits flow into the reservoir to a

predetermined volume.

Solenoid shut off Allows the reservoir to fill only during set

times.

Pressure reducing Reduces downstream pressure whilst the

reservoir is filling

Closing speed control

Other Options Model 13112A-28 One-way flow. Valve closes at a predetermined top water level. Valve reopens when water level drops. Model 13112A-29 One-way flow with delayed opening. Valve closes at a predetermined top water level and reopens when the water level drops to a predetermined low water level. (This is adjustable from 1.3 metres to 3.6 metres below top water level). Model 13112A-30 Two-way flow. Valve closes at top water level and opens again for return flow when pressure at the inlet of the valve is below the reservoir head pressure. Model 13112A-31 Two-way flow with delayed opening. Two way flow with delayed opening of the return flow. Valve closes at top water level and reopens for return flow only when the line pressure at the valve inlet drops to a predetermined reservoir level.

MACK REMOTE SENSING PRESSURE REDUCING CONTROL


The 410 pressure reducing valve automatically reduces a higher inlet pressure to a lower outlet pressure.

It is a direct acting, spring loaded, diaphragm type valve that

operates hydraulically or pneumatically, and is designed to sense pressure from a remote point.

As a pilot control it will cause the main valve to hold a

relatively constant down stream pressure at the remote sensing point.

Spring Setting Range: 50 – 500 kPa Spring part no. 1935-0H3-062 501 – 1300 kPa Spring part no. 1935-0K3-062 1301 – 2100 kPa Spring part no. 7018-026-062

Adjustment Procedure Pressure adjustment is made by turning the adjustment screw to vary the spring pressure on the diaphragm. The greater the compression on the spring, the higher the pressure setting.

1. Turn the adjustable screw clockwise to increase downstream pressure.

2. Turn the adjustment screw anti-clockwise to

decrease downstream pressure. When pressure adjustment is completed, tighten lock nut on adjustment screw and replace cap.

Model No. 410

MACK PRESSURE RELIEF CONTROL

Adjustment Pressure adjustment is made by turning the adjusting screws to vary spring pressure on the diaphragm. The greater the spring compression, the higher the pressure at which the valve opens. Turn the adjusting screw clockwise to raise the pressure relief setting. The adjusting screw is protected by a bronze housing, which is drilled to accommodate a lead-seal wire. The pressure relief control valve can be adjusted to provide a relief setting at any point within the range stamped on the nameplate.

Installation Install as shown in look up diagram of complete valve assembly; be sure to connect control tubing as shown. This control may be installed in any position. Allow sufficient room to make pressure-setting adjustments when installation is complete.

Disassembly Disassembly of the valve requires no special tools. The control does not need to be removed from the line. Back out adjustment screw to remove spring tension before removing cover.

Inspection Inspect valve disc for scoring, or embedded foreign particles. Inspect diaphragm for excessive wear and other damage. Check all parts for damage, corrosion, excessive wear and minimal deposits.

Repair &Replacement Replace all parts, which are damaged. When ordering replacement parts, be sure to specify catalogue number, and all nameplate data.

Reassembly Reassembly is the reverse of disassembly; no special tools or jigs required.

Test Procedure No testing of the pressure relief control is required prior to

The 405 differential control closes when controlling pressure exceeds the predetermined setting.

The valve is designed for use in conjunction

with Model 13112A-11 rate of flow valve and Model 13112A-12 combination pressure reducing and rate of flow valve and operates within very tight pressure limits.

The valve is actuated by the differential

produced across an orifice plate in the main line. Accurate control is assured as very small changes in the controlling differential produces immediate corrective action of the main valve.

Rate of flow is adjustable by varying the

spring load on the control.

The 406 altitude control senses pressure in the

reservoir when reservoir pressure (liquid level) is
lower than the set point of the valves. Ports (1) and (D) are interconnected.
1

The valve relieves cover pressure to atmosphere, and the main valve opens to fill the reservoir. Reservoir sensing pressure increases as the liquid rises in the reservoir.

When reservoir pressure increases to the set point,

the control shifts interconnecting ports (S) and (1).
3 This pressurises the cover of the main valve, which causes the valve to close. Rate of flow is
adjustable by varying the spring load on the control.

The Cv factor is defined as the flow of water which will pass through a valve for a given head loss. The Cv factors for Mack automatic control valves are listed in imperial and metric units.

Cv1 = Flow rate in gallons per minute at 1 psi head loss

Cv2 = Flow rate in litres per second at 1 kPa head loss

Cv3 = Flow rate in litres per second at 1 metre head loss
