Stainless steel lithium battery back pressure valve: used to prevent liquid from flowing or siphoning under gravity, in which case the stainless steel back pressure valve can reduce the flow and pressure fluctuations caused by siphoning.

Design features of stainless steel back pressure valve

1. Spring diaphragm structure, adjustable pressure (see parameter table for pressure adjustment range)

2. The only parts that come into contact with the medium are the lower valve body and the diaphragm. The sealing area between the lower valve body and the diaphragm is processed with sealing ribs, which have good sealing effect and high sensitivity

3. The conventional membrane adopts EPDM lined PTFE form and is processed with cloth clamping, which has good sealing effect and high service life; Pure PTFE membrane has high temperature resistance and strong corrosion resistance

Scope of application of stainless steel back pressure valve

1. Chemical industry, water treatment, laboratory

2. Corrosive liquids, ordinary gases

Characteristic parameters of stainless steel back pressure valve:

1. Adjustable pressure 0-0.3MPa, 0-1.0MPa (see parameter table for details)

2. Security testing pressure: 1.5 times greater input pressure

3. Applicable temperature: ordinary diaphragm -5 ℃ to+80 ℃); PTFE membrane: -5 ℃ to+80 ℃)

Material:

1. Lower valve body material: PVC, SS304, SS316L, PTFE, PVDF, PP, carbon steel, etc. (can be customized according to requirements)

2. Membrane material: EPDM lined PTFE (composite membrane), PTFE (polytetrafluoroethylene)

3. Upper valve body material (not in contact with the medium): PVC, carbon steel (spray treated, electrophoretic paint treated), 304 stainless steel, 316L stainless steel
