Pressure-Tru Sprinkler and Hose Valve OperationPressure-Tru valves reduce high inlet pressure to a lower downstream pressure. • Valve opening force is created by high pressure (A) pushing
against the plunger (1). The Z2100 and Z3000 are equipped with an adjustable spring (2) to assist.
• Closing force is created by downstream pressure (B) transferred through an orifice in the stem (4) and acting upon the large piston area (3)
• The balance of opening force and closing force result in pressure regulation
Under normal conditions, the downstream side (B) is pressurized, holding the valve in the closed position. In the event of water demand from a discharging sprinkler head or hose nozzle, the lower downstream pressure decreases, allowing the valve to open. The valve will modulate between open and closed to satisfy both demand and pressure.For service and maintenance, manually hold valve in the closed position by rotating the hand wheel (5), which forces the plunger onto the seat.Monitoring options include the integral supervisory switch (SS) to monitor the open/closed position of the valve, or bracket (MSA) to mount an external supervisory switch.
Z2100 and Z3000 Series Field Setting Features• Field adjusting is accomplished with a tamper resistant
adjusting nut, and is adjusted with a socket and ratchet• Can be adjusted without draining the standpipe or system,
speeding adjustment• Ideal for installations requiring adjustability
of outlet pressure• Factory set available if required
Choosing the Correct SettingRefer to Residual Pressure Flow Charts and Static Pressure Charts (available on zurn.com) and the following procedure to choose the correct setting for each valve:1. Determine required downstream demand in gallons
per minute.2. Determine standpipe residual or “flow pressure” at the
valve inlet.3. Select appropriate flow chart based on GPM required,
valve type, and size.4. Determine correct setting (letter designation) based on
the intersection between valve inlet residual pressure and outlet residual pressure.
5. A minimum of 20 psi pressure differential is recommended to assure efficient system performance (difference between the inlet static pressure and outlet set static pressure).
Valve Care and Maintenance• Flush the system to remove any rocks or debris.• Upon installation, fill system slowly to prevent
water hammer.• Periodically test the valve, allowing it to open and reset.• Drain system for repair, and remove bell housing and flange
to access internal components without removing valve body from system.
• Repair parts available, contact your local Zurn representative
CAUTION: To prevent a false reading during the setting process it is necessary that a test valve be opened and closed downstream to relieve the locked-up pressure in the system.
Note: NFPA 13 requires a pressure relief valve on sprinkler systems downstream of pressure reducing valves.
