Overview

A hydrogen production test back pressure valve with an electronic pilot regulator may be a good choice for pressure process control. It has stable flow and can be used in a wide range of working conditions, such as high flow, high temperature and high pressure, precise pressure control, and battery stack testing.

Product Details

1、 Product Overview

Presreg-RCR Back pressure valve is a precision control component designed for the pressure stability requirements of industrial fluid systems. Through a collaborative mechanism, it achieves adaptive pressure regulation and can effectively counteract system pressure fluctuationsSystem pressure controlWait for the process to provide a constant back pressure environment. Relying on the advantages of localized supply chain, its standard model delivery cycle is shortened compared to imported brands95%Urgent orders48 You can respond within hours.

3、 Key Structure and Working Principle

1. core componentComposed of valve body, regulating mechanism, diaphragm sealing component and pressure feedback hole, the diaphragm adoptsPTFEOr made of metal material, ensuring zero leakage sealing (leakage rate)≤1×10 ⁻⁶ Pa・m³/s）.

2. working mechanism：

◦When the system pressure is less than the set value,gas sourcePush the diaphragm sealing valve seat to block fluid flow;

◦When the pressure reaches the set value, the medium thrust and the diaphragm lift off the valve seat to form a flow channel;

4、 Typical application scenarios

1. Adaptation to key industries

industry sector	specific application	Recommended Series

5、 Installation and maintenance

1. Installation specifications：

◦Installation should be marked according to the flow direction of the medium (reversing the inlet and outlet will cause the back pressure to double), and it is recommended to be near the filling point or pump outlet;

◦The medium containing solid particles needs to be pre filtered with a three-way filterOr specific media containing solid particulate matter seriesEasy to clean online.
