Series 853

Corrosion-resistant valves made of gunmetal: the ideal alternative to stainless steel.

Our valves made of corrosion-resistant gunmetal offer a robust and durable alternative to stainless steel valves. The design corresponds to the proven valve series 453, with the decisive advantage of a media-resistant housing material. Thanks to the flexibility in the choice of seal materials, these valves are suitable for almost any medium, from aggressive chemicals to neutral gases.

For applications with high back pressure, we offer valves with back pressure-compensated pistons that ensure reliable operation even under extreme conditions. The valves can be factory-set to the desired pressure and sealed, or the user can easily adjust the pressure setting within the intended spring range using the handwheel.

A particular advantage of these valves is the option of making adjustments or setting the valves during operation, which increases flexibility and efficiency in use.
