Back Pressure Valves are designed to enhance the performance of chemical feed systems by applying a continuous back pressure to the chemical dosing pump. they are widely used in chemical industry, water treatment, laboratory etc., also our back pressure valves are suitable for air and various kind of corrosive liquids. Diaphragms: PFTE / EPDM Product Body: PVC,PVDF, carbon steel, SS304,SS316L Adjustable pressure: 0-0.3MPa，0-1.0MPa Connection type: Thread / Flange, can be customized
PTFE Back Pressure ValvePTFE Back Pressure Valves / Pressure Relief Valves PTFE Back pressure valve is used to prevent liquid from flowing or siphoning due to Gravitation. At this time, the back pressure valve can reduce the flow due to siphon and control the pressure fluctuations. The back pressure valves we manufactured are widely used in chemical industry, water treatment, laboratory etc., also our back pressure valves are suitable for air and various kind of corrosive liquids. Connection type Thread, flange etc. and can be customized Adjustable pressure 0-0.3MPa，0-1.0MPa Safety test pressure 1.5 times the maximum input pressure Applicable temperature -5℃ to +80℃ for EPDM lining…- PVC Series Back Pressure ValvesAll thermoplastic diaphragm Back Pressure Valve for chemical feed systems, applies back pressure to a metering pump to prevent siphoning and eliminates varying dosage rates resulting from fluctuating downstream pressure. When the preset pressure is exceeded, the diaphragm is forced up and chemical flows through the valve to the injection point. All valves are preset for 50 psi, but are field adjustable via the adjustment screw. Installation should be as close to the injection point as possible to prevent chemical line drainage and it is most important that all chemical system equipment such as pulsation dampeners and pressure gauges are…
