VMRNA valve is a reverse acting solenoid valve: when de-energized, the valve is open (N.O. normally open). The valves are made of aluminum alloy with connections from 3/4” or 1”½.
The VMH type valve is a safety shut off valve for gas with hydraulic actuator. It is suitable for air or gas blocking and releasing controls, required in the main pipe of gas power burners
VMR type valve is a fast opening single-stage solenoid valve, normally closed & suitable for air or gas blocking, releasing controls, required in gas power burners, atmospheric gas boilers
The LD/LDM tightness control device is designed to verify the absence of inadmissible leaks in gas trains composed by automatic shutoff valves.
The RS type is a regulator for gas pipelines according to EN 88. It is equipped with a safety shutoff valve that blocks gas flow in event of outlet pressure being too low or too high.
The VS type is a pressure relief valve to reduce temporary pressure surge in burning appliances. The shutting-off of automatic valves or non-tightly closing of regulators can cause pressure increase
Modulating valves LMV are used in combustion processes that require linear adjustment of gas flow. It can be operated with stage control or with continuous modulation (analog signals, MZ5 servomotor)
Safety solenoid valves for air and gas from delta elektrogas has many models such as VMM, vmh, vmr, vml, and VMRNA
The VML is a safety valve that is normally closed,with fast or slow opening & adjustable rapid section for initial gas flow.When not in working position the spring works on the disc keeping the gas…
