FREE-VALVE plastic pressure release safety valve is installed in the line of positive pressure discharge of metering pump,its function is to prevent siphon phenomenon occur.Removing the protective cap on the adjusting screw on site, then rotating and adjusting screw , the required pressure will be got by adjusting pressure gauge in the pipeline. Back pressure will be set within the range of 0-0.6 MPa by adjusting screw .
1.It reduces damage to the system by water hammers, so that the system will achieve superior low vibration effect.
2.It will keeping a certain constant pressure from the pump outlet port to the back pressure valve.
3. Keep the system flow rate is constant.
4. Keep the stability of system pressure.
5.Smoother than metal for better flow rates.
6.Working temperature: FRPP -14ºC~ +90ºC,UPVC -10ºC~ +60ºC,PVDF -40ºC~ +150ºC,CPVC -20ºC~ +95ºC
FREE-VALVE plastic pressure release safety valve is widely used in chemical industry, water treatment, laboratory, corrosive liquid, ordinary gas and other fields.
