Chuck type back pressure valve

Product Overview

Chuck type back pressure valvealso calledQuick installation back pressure valve is a commonly used back pressure valve used to stabilize the pressure in front of the valve, prevent pump self flow and siphon, and is often used in conjunction with a metering pump to improve the metering accuracy of the metering pump.Mainly used in the lithium battery new energy industry, the advantages are easy disassembly and cleaning, reasonable internal design, material 304 stainless steel, sealed PTFE PTFE PTFE

Design characteristics of chuck type back pressure valve

1. Spring diaphragm structure with adjustable pressure (see parameter table for pressure regulation range), providing stable pressure in front of the valve;

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.

Product Technical Data

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

2. Safety testing pressure: 1.5 times the maximum input pressure

3. Applicable temperature: Ordinary film: -5 ℃ to+80 ℃

4. PTFE membrane: -40 ℃ to+150 ℃

Material

1. Material of the lower valve body (overcurrent component): PVC, SS304, SS316L, lined with fluorine PTFE.PVDF、PP、 Carbon steel, Hastelloy, etc. (can be customized according to requirements)

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

3. Upper valve body material: Nylon, carbon steel (electrophoretic paint treatment, spray coating treatment), SS304, SS316L, etc., can be customized according to requirements
