Pilot self-operated (downstream) pressure control valve, consisting of a control valve, actuator, and a pressuren setting controller. Suitable for non corrosive liquid, gas, and steam. It controls the downstream pressure in system pipelines. When downstream pressure rises, the control valve opens.
FEATURES:
Energy saving: No need for external energy, use the pressure of the pipeline itself for regulation
Simplified system: No need for external control instruments, simple system with low cost
High safety: Used for non electric and non gas situation, with no risk from external energy sources
Easy to operate: Simply rotate the adjusting nut for setting
Reliable quality: Low noise, maintenance free, and reliable performance
Advantages: With pressure balancing function, high sensitivity
Assembly: Through the assembly of components, multiple combination controls can be performed
Note: The working environment is outdoors, so protective devices need to be installed and insulation work should be done well in cold northern regions
