They are generally installed on equipment or pipelines in closed systems to protect system safety. When the pressure inside the equipment or pipeline exceeds the set pressure of the safety valve, it automatically opens to release pressure, ensuring that the medium pressure inside the equipment and pipeline is below the set pressure, protecting the normal operation of the equipment and pipeline, preventing accidents, and reducing losses.

Design features

Spring diaphragm structure with adjustable pressure (see parameter table for pressure adjustment range)

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

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

Chemical industry, water treatment, laboratory

Corrosive liquids, ordinary gases

Characteristic parameters:

Adjustable pressure 0-1.0MPa, 0-2.0MPa, 0-3.0MPa (see parameter table for details)

• Safety testing pressure: 1.5 times greater input pressure

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

Material:

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

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

Upper valve body material: PVC, carbon steel (nickel plated, blackened), 304 stainless steel, 316L stainless steel

When purchasing a safety valve, please provide the following data:

1. Diameter of safety valve

2. The pressure that needs to be set

3. What material and connection method are needed to better inform the conveying medium, temperature, and flow rate at the same time.
