Product Overview:

SZJHQ pneumatic film three-way combination regulating valve, SZJHX pneumatic film three-way shunt regulating valve adopts cylindrical thin wall window spool guide, which is different from the bushing guide of plunger spool. With multi spring actuator, has the advantages of simple structure, light weight, small volume, convenient disassembly and assembly. It is widely used to accurately control the process of gas, liquid and other media, such as pressure, flow rate, temperature, liquid level to keep in the given value. Suitable for a kind of fluid through the three-way valve into two outflow or management of two kinds of fluid through the three-way valve combined into a fluid occasions pneumatic film three-way regulating valve with three-way and three-way shunt two kinds. Nominal pressure PN16, 40, 64; Nominal diameter range DN25 -- 300. Suitable for fluid temperature from -60ºC to +450ºC. The leakage standard is class 4. The flow characteristics are linear and parabolic.
