Witt extends line of gas nonreturn valves with Ultra 30 and 40

Witt-Gasetechnik has added the Ultra 30 and 40 models to its line of Ultra gas nonreturn valves. The flow-optimized valves in this line deliver high flow rates despite their small size. With an opening pressure of about 0.058 PSI, they are suitable for low-pressure applications.

The new models extend the line, which now includes four models with type-dependent connections from ½ to 2-1/2 in. Valves can be configured to meet specific requirements. Brass, stainless steel, or aluminum housings can be combined with sealing materials such as FPM, EPDM, or FFKM.
