Self-operated flow control valve, consisting of a flow setting control valve and actuator. Suitable for flow control of non corrosive liquid in system pipelines.
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
Reliable performance: Adjust the flow rate according to the throttle valve standard diagram, convenient and fast
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
