Technical Specifications:

Pressure: 0～0.8MPa (standard instrument air supply operating pressure)

Temperature: -40℃ to 120℃

Chemical SuitRespondCompatibility: Designed for clean gas sources such as dry compressed air and instrument nitrogen; resistant to mild oil, vapor, and moisture corrosion.

Material: Rubber composite with fabric-reinforced fiber skeleton, typically molded and vulcanized from nitrile rubber (NBR), ethylene propylene diene monomer (EPDM), or fluoroelastomer. High-strength fabric reinforcement enhances tensile strength and resistance to reciprocating fatigue.

Product Features: Circular flange with mounting bolt holes; pleated bellows structure offers large stroke and withstands thousands of reciprocating bends without tearing; fabric-reinforced construction ensures stable deformation and uniform rebound, precisely converting air pressure into valve stem thrust; tight edge sealing prevents leaks to guarantee precise valve travel.FisherCore wear parts for diaphragm actuators: easy to install and replace.

Applications: Paired with imported control valve actuators; widely used in chemical, petroleum, power generation, and water treatment industries for automatic flow, pressure, and level regulation in process control systems.
