Rubber diaphragms are flexible seals that prevent unwanted transmission of substances between two places. These substances can be liquids, gases or solutions. The flexible nature of this diaphragm allows pressure effects to cross the barrier but not the material being contained. Diaphragms are also used to protect a process fluid from the pressure sensor. They are characteristically tough & dynamic and essential in many flow control applications. Diaphragms can be manufactured to suit a wide variety of applications, which can be found in all sections of Industry.

Diaphragm has wide applications include Electrical & Pneumatic Control Valves, Pressure Regulators, High Pressure Pump, Gas Regulators, and Pressure Relief Valve etc. Diaphragm Materials range are NBR, SILICON, EPDM, NEOPRENE however Exact material specifications should be clarified by our engineers, as chemical and physical properties of grommets can differ based on manufacturing technique & application.
