Siemens Biogases and Recycling Gases Valves VRF10 VRH10

VRF / VRH Safety Shutoff Valves

The VRF and VRH series are safety shutoff valves developed for specialized industrial applications. They are suitable for use with air, gases from families I…III, as well as slightly aggressive biogases and recycling gases.

These valves are particularly designed for processes involving biogas and recycling gas, where chemical composition and aggressiveness vary depending on operational factors.
