DN50 Stainless Steel Stainless Steel Pn16 Indurtail Flange Pressure Relief Valve

A flange pressure reducing valve is a type of pressure reducing valve that uses a flange connection method, mainly used to regulate the flow and pressure of media. It is widely used in fields such as chemical engineering, petroleum, natural gas, and water treatment.

The flange pressure reducing valve is different from the general threaded pressure reducing valve. Its connection method is flange, which uses the opening of the opening and closing parts inside the valve body to regulate the flow of the medium, reduce the pressure of the medium, and adjust the opening of the opening and closing parts with the help of the pressure behind the valve, so as to maintain the pressure behind the valve within a certain range. In the case of continuous changes in inlet pressure, the outlet pressure is kept within the set range, protecting the subsequent living and production equipment.

Application scenarios

Petrochemical industry: The pressure of the reactor feed pipeline is stable.

Power industry: Boiler feedwater system depressurization.

Natural gas transportation: secondary pressure reduction in station pressure regulating pry.

Working Principle

When the fluid passes through the valve core, the pressure decreases due to the throttling effect, and the pressure on the outlet side is transmitted to below the diaphragm through the feedback pipeline. When the outlet pressure fluctuates, the diaphragm drives the valve core to move and automatically adjusts the opening to maintain the set pressure.
