Product Details

Z515N internal feedback self operated pressure regulating valve

The Z515N type internal feedback self operated pressure regulating valve is a type of self operated pressure regulating valve developed and researched by our company for working conditions with high medium viscosity and easy coking. It avoids the situation where conventional self operated pressure regulating valves are difficult to maintain insulation, the pressure pipe is prone to blockage, and the regulation accuracy is affected. Suitable for automatic control of pressure relief and stabilization in high viscosity and coking prone media. This product has the characteristics of energy saving, sensitive action, reliable operation, and convenient operation and maintenance. Widely used in industries such as petroleum and chemical engineering for automatic control of pressure relief and stabilization of high viscosity media such as crude oil.
