| Message: | PR series forerunner pressure regulate valve is widely used on large-scale refrigeration equipment, it can control the system evaporating pressure, condense pressure and regulate the energy unload in compressor. PR series forerunner pressure regulate valve can include:PRD exhaust pressure regulate valve- it can ensure the compressor to maintain a consistent exhaust pressure, to avoid overload.PRE evaporating pressure regulate valve- it can help refrigeration system to maintain a proper evaporating pressure, is benefital for the performance of the compressor under a stable suction pressure. It can also used to control the temperature to avoid the frozen of the evaporating machine.PRC pressure differential regulate valve- it can keep the stability of the pressure differential between the front and the back of the valve, it can used to vacuum unload the high and low pressure.It can also come out other models according to the system requirement, to control and maintain the inlet pressure at a stable range.Technical Spec: Connection Dimension: 10～32 mmPressure regulate range: high pressure: 0.5～2.0 MPa, low pressure: 0～0.7 MPaMax. working pressure: 2.8MPaMax testing pressure: 3.5 MpaMin open pressure differential : 0.01MPaMedium Temperature range: -12～120°CCan be used in R134a、R22、R407C、R404A/R507、R717Adjust range: 0.5~1.7MpaConnection size: 80mm. url:http://www.fs-controls.com |
