Pressure regulating valve (self operated)

Technical Parameters

Pressure regulating valve (self operated) Product model: V230Y
Nominal diameter: DN20~300mm
Nominal pressure: PN1.6, 4.0 MPa
Applicable temperature: ≤ 350 ℃

Product Details

Product Overview
The V230 self operated pressure regulating valve is composed of valve body, valve seat, valve core components, etc. It is an energy-saving product that does not require external energy and only relies on the pressure changes of the regulated medium to automatically adjust the pressure. It can be used as a pressure control device for non corrosive liquids, gases, and steam. Compared with the ZZYP series, the control spring has the characteristics of being far from the valve body, less susceptible to medium temperature, and easier to replace or adjust the spring. Therefore, self operated pressure regulating valves are widely used in industrial sectors such as petroleum, chemical, metallurgy, light industry, and urban heating and heating systems. The self operated pressure regulating valve series products have a nominal pressure of PN16 and 40, a nominal diameter range of 20-300mm, and a service temperature of ≤ 350 ℃. A variety of varieties are available for selection. It has a larger pressure difference range than the old model.

Product Features
(1) The self operated pressure regulating valve does not require external energy and can work in places without electricity or gas, which is both convenient and energy-saving.
(2) The pressure segmentation range is fine and intersects with each other, with high adjustment accuracy.
(3) The pressure setting value can be continuously set during operation.
(4) The ratio of front valve pressure to rear valve pressure can be between 10:1 and 10:8 for regulating the pressure behind the valve.
(5) Rubber diaphragm type detection, with high measurement accuracy and sensitive action of the actuator.
(6) Adopting a pressure balancing mechanism, the regulating valve responds sensitively and controls accurately.
