Self-Operated Pressure Regulator
Brief Description1.5811 Type Self-operated pressure regulators do not require any external energy, so that It can be worked without gas or electric, convinient and Energy saving2. Meticulous segmented pressure range
Details1.5811 Type Self-operated pressure regulators do not require any external energy, so that It can be worked without gas or electric, convinient and Energy saving
2. Meticulous segmented pressure range and cross-cutting, high regulation accuracy
3.Pressure settings can be set during continuous operation.
4.For the pressure over the valve, Pressure ratio between before valve and after valve is 10:1 to 10:8.
5.Rubber diaphragm type detection, high measurement accuracy actuators, sensitive motion
6.Using pressure balance mechanism, so that the control valve is responsive, precise controlled.
