Product features
Hydraulic control, without external driving force;
The main valve has only one moving part, so the failure rate is low;
Diaphragm structure, no friction, high control sensitivity;
The pressure behind the valve does not change with the pressure in front of the valve;
The pressure behind the valve does not change with the flow rate of the system;
Good static pressure reduction effect;
The pressure regulation range behind the valve is large.
