Self-Operated Valve Series
Description
The ZZVP series self-operated micro-pressure control valve is an actuator product that requires no external energy source, relying on the energy of the controlled medium itself to achieve automatic regulation. This product features a balanced single-seat valve with a quick-opening flow characteristic adjustment mechanism, providing stable medium pressure, high regulation accuracy, and reliable sealing performance. It allows adjustment of the setpoint at any time during operation.
Share:
No external driving energy required, simple structure.
Adjustable set point with a wide range.
Balanced structure ensures stable pressure.
Low friction, high sensitivity and high regulation accuracy.
It is applicable for scenarios such as automatic micro-pressure regulation of fuel gas in various industrial furnace combustion systems, protective gas for petroleum intermediates or oil storage tanks, and protective gas for heat treatment processes.
