Product Description

Our manuafctured Safety valve/pressure relief valves for dosing metering pumps are widely used in chemical industry, water treatment, laboratory etc., also our Safety valve are suitable for air and various kind of corrosive liquids. Safety valve is generally installed on the equipment of closed system or pipeline to keep the system safety.

Design features:
(1) Spring diaphragm structure, adjustable pressure (see parameter table for adjustment range), overpressure relief, protecting the safety of equipment and pipelines.
(2) Only the lower valve body and diaphragm are in contact with the medium. The sealing part of the lower valve body and diaphragm is processed with a sealing rib, which has good sealing effect and high sensitivity.
(3) The conventional diaphragm is made of EPDM lining and Tefon, with good sealing effect and high service life. The pure Tefon diaphragm has high temperature resistance and strong corrosion resistance.
