Straight acting back pressure valve can maintain the required pressure and flow of the line, while discharging excessive pressure.Overcome the general pressure relief valve pressure relief can not hold the shortcomings of pressure.

（1）Inlet pressure regulating range：1kgf/cm²—6kgf/cm²

                                                              4kgf/cm²—10kgf/cm²

                                                              8kgf/cm²—13kgf/cm²

（2）Service temperature: 0℃—80℃

（3）Pressure gauge shows outlet pressure

（4）Nominal pressure PN1.0Mpa—1.6Mpa，Specifications DN15-DN150。

（5）RFF type uses flange connection and RFT type uses threaded connection.

Special media, higher service pressure or temperature can be customized.
