Product Description

Features of PVC Series Back Pressure Valves

• With Diaphragm structure spring and the pressure will be adjustable.
• The medium contacting parts are only the lower valve body and the diaphragm and they are assembled with sealing rib which has good sealing effect and high sensitivity.
• EPDM lining PTFE with Cloth type diaphragm has a very good sealing effect and long service life, The PTFE type diaphragm has a very good performance in high temperature resistance corrosion resistance.
