Product Details

1、 Overview of Self Operated Pressure Regulating Valve
ZZYP type self operated pressure regulating valve is a type of valve that does not require an external energy source. It uses the energy of the controlled medium itself as a power source, introduces it into the actuator chamber to generate thrust, and controls the movement of the throttling element to achieve automatic regulation. It has comprehensive functions of measurement, execution, and control. Can be used in places without gas or electricity. Widely used in the automatic control systems of various equipment gas, liquid, and steam media in the petroleum, chemical, power station, light industry, and printing and dyeing industries for deceleration pressure, stabilization (used for post valve pressure regulation), and automatic control of pressure relief and stabilization (used for pre valve pressure regulation). According to different working conditions of users, different types of valve core structures and actuators can be selected to achieve the desired control effect.

2、 Model of self operated pressure regulating valve

category	model	category	model
Single seat pressure closed type	ZZYP-16～64B	Single seat pressure closed type	ZZYP-16-64K
Double seat pressure closed type	ZZYN-16～64B	Double seat pressure closed type	ZZYN-16～64K
Sleeve compression closed type	ZZYM-16～64B	Sleeve compression closed type	ZZYM-16～64K

Pressure closed type: used for regulating the pressure behind the valve. When the pressure behind the valve increases, the valve closes to achieve the purpose of pressure reduction and stabilization.
Pressure open type: used for regulating the pressure behind the valve. When the pressure behind the valve increases, the valve opens to achieve the purpose of pressure relief and stabilization.
