CY41H Series Pilot Operated Diaphragm Pressure Reducing Valve
CY41H Series Pilot Operated Diaphragm Pressure Reducing Valve
 

Applications

  

1.The valve is an innovation with latest design to depend on different customers needs by the introduction of a high technology.

2.Especially suitable for use with steam, compressed air or other industrial gases, 

has a maximum operating temperature of 285 and is available in sizes from DN15 to DN150.

3.Typical applications include lowering the pressure of steam from a high-pressure distribution line to the point of use and as an automatic temperature control for 

applications such as autoclaves, retorts, and corrugators.

Features   

1.Covers downstream pressures from 0.0MPa to 1.Mpa, with variable rate pressure 

control spring.

2.Works by balancing the downstream pressure against the control spring, which then 

modulates the main valve via a small pilot valve.

3.The valve can now be changed to an application with a different pressure requirement 

without the cost of changing the control spring.
