Manual Reset Safety Valves

Manual Reset Safety Valves EVRMNC EVRM6NC
Safety solenoid valves for gas with manual reset, normally closed
The EVRM-NC type valve is a manual reset safety valve that is normally closed. When the coil is not energized the spring works on the shutter keeping the gas passage closed. Simply by energizing the coil the valve does not open. It is necessary to manually move the reset rod located at the top of the coil. Once opened, the valve can maintain this position until electric current circulates on the coil. In absence of electric current the valve closes rapidly and remains shut upon return of same. Once the causes for the lock have been eliminated, opening must be worked manually as described above.
This type of device, connected with one or more pressure switches is suitable for locking operations upon gas, air, or electric current failure, and is qualified for continuous service (permanently live).

Electrogas Control Valve Model VF VFH

Detail Elektrogas Control Valves VF VFH
VF VFH
Butterfly valves for air and gas
VF and VFH butterfly valves are designed for regulation and control of air and gas flow.

Valves can be operated manually using a lever (to setup the high-fire rate of the burner) or automatically using a servomotor (modulating or staged control) or a solenoid actuator (two-stage control).
The setting can be monitored on a graduated scale, this allows  precise regulation ratios.
This type of device is suitable for air and gas adjustment in combustion processes, like industrial kilns, drying stoves, smelting and annealing furnaces.
