Characteristics

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.

1.Pressure hole of low pressure cavity is built-in, reduce an external connectingpipe, which avoids damage during installation.

2.Target differential pressure value can be setted by hand wheel,it is moreconvenient. Every number on the hand wheel is corresponding to one settedvalue. Pre-setting function can be realized easily on site.

3.This valve has manual closing function, plug allen wrench into the center of handwheel, rotate it to open and close the valve.

4.Balancing diaphragm and spring are built-in, it is nice and reliable.

5.External high pressure testing point, there is locking function, one allen wrenchcan lock external connecting pipe.

Operating Instruction

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 testing point②.Now the system is in a state of low pressure.2.Open the plug of air hole③,then open the 3-port measuring points 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.

Cut off function: on the top of hand wheel⑤,close the valve by allen wrench.

Testing point④Remove the cover and then insert the probe into self-sealing testing point.

Capillary pipe①2m capillary pipe is optional if longer one is needed.Attention!Must use matched capillary pipe.

Note:DN = CaliberPN = Pressure class. If PN25 is needed,change C to D in valve type. e.g.TYL25-2VTD-30Materials:Valve body:brass Hpb59-1, Valve Stem:Stainless Steel,Valve Core:Stainless Steel, Diaphragm:EPDM
