Diaphragm Valves Construction

Constructed from 316L VIM/VAR (single and double melt) stainless steel, diaphragm valves are available in both low and high-pressure models. The valve body is designed with minimum dead space and maximum flow capacity and the electropolishing process enables it to withstand corrosive environments.

Valve seat offers excellent resistance to chemicals, low coefficient for thermal expansion, a minimal particle of contamination, and a long lifecycle. The diaphragm is constructed from Elgiloy® material and the electropolishing process also provides excellent resistance to corrosion. Valves have a pressure rating of 250 psi (17 bar) and a temperature rating from -10°F to 150°F (-23°C to 65°C). Sizes include 1/4″ and 1/2″ and end connection options include male/female ZCR fittings, Hy-Lok tube fittings, and tube butt welds for maximum compatibility. For mounting, valves feature a panel mounting nut making it simple and easy to mount the valves. Manual handle or pneumatic actuator are available and all diaphragm valves are 100% helium leak tested.

Sanitary diaphragm valves are assembled in a Class 10 cleanroom and packaged to meet the strict standards of the hygienic processing industry. Internal surface grades include High (Roughness average Ra. of 0.13 µm / 5 µin.) and Super (Roughness average Ra. of 0.1 µm / 4 µin.).

Hy-lok is a global leader in industrial valve solutions and technology. Hy-Lok diaphragm valves are excellent solutions for gas and liquid regulation in a broad range of industrial settings. Their quality and reliability can be depended on for long cycle life and trouble-free operation.
