Rev.A

Differential pressure control valve(DPCV) can keep the differential pressure at two sides of load constant,that can improve the stability and accuracy,reduce the noise,and easy to balance and commission.

DPCVTYL...Series

Features Introduction

Digital Handwheel

The DP can be set by rotating the handwheel and the number on handwheel can show the cycles which is easy for operation and convenient for debugging and recording.

Close off Function

The valve has the close off function, the valve can be locked by an Allen wrench which is convinient for on-site maintenance.

Build-in Diaphragm Capsule

The va lve adop ts the bu i ld - in diaphragm capsule which could make the valve smaller and significantly avoid damaging during installation compared with external connecting pipe.

3-port Test Plug with Close off Function

Closing the test plug can avoid the tube from blocking during washing pipes. During normal use, keep the test plug open so as to achieve the balancing function of the valve.

1.Connect capillary pipe①, As shown in the installation diagram,one end of

capillary pipe connects DPCV,the other end connects with static balancing

valve through 3-port test plug②.Now the system is in a state of low

pressure.

2.Open the plug of air hole③,then open the 3-port test plug ②. Pour water

into pipeline until it exhausts all the air in valve cavity,and lock the air hole

plug ③.

3.As shown in the installation diagram,use digital differential pressure

meter(see page 5) to measure differential pressure of P2 and P3,that is

△PL .

4.Setting △PL, by rotating the hand wheel⑤. Accurately adjust the data

according to data of digital pressure meter.

Shut off function: on the top of hand wheel⑤,close the valve by allen

wrench.

Test plug④

Remove the cover and then insert the probe into selfsealing test plug.

Notes: High pressure end is in red, low pressure is in blue.

HP and LP can't be reversed!

Capillary pipe①

2m capillary pipe is optional if longer one is needed.

Attention! Must use matched capillary pipe.

Installation Instruction

Notes:The DPCV usually be installed on the return pipe and setted according to correct water flow direction.

Pay a t t en t i on t o med ium f l ow direction!Pay attention to the reversed height for valve, which is easy debugging and maintaince.

Debugging Instruction

1.Open the 3-port test plug.

2. Open the plug of air hole and lock the air hole plug after it exhausts all the air in valve body.

3. Rotate hand wheel to set the DP. 4. Close off function: rotate clockwise to tighten the valve.

Type Selection

1. Select the desired △PL from the tables.2. Select the same size of the valve as the pipe.3. Check that the desired flow is smaller than the specified qmax.If not,select themost similar large dimension,or a larger △PL.

The tables work in the following situation：ΔH≥2xΔPL，the valve will work effectively from 2*△PL to 250kpa+△P
