912
The 912 is a 3-way push-button valve for safety shutoff valve (SSV) measuring lines, and for manual release function via underpressure shut-off.
914
The 914 is a test valve that is ideal for installation in measuring lines of safety devices
915
The 915 is a vent valve that is well suited for protecting the installation room against inadmissible gas leaks from diaphragm assemblies. In case of a defect, it limits the leakage to the preset limit value (with respect to air in normal condition)
916
The 916 test combination is a device for adjusting and testing safety shut-off valves (SSV) and safety relief valves (SRV).
917
The 917 is a monitoring device for leakage gas flows. It is ideal for use with safety relief valves (SRV) as it can indicate opening of the relief valve and simplify the monitoring of SRV response and SRV setpoint adjustment.
925
The 925 over-pressure protection fulfils the requirements of DVGW worksheet G 491
983
Gas mixer with variable mixing gap
981
Throttle valve for gas engines
