Gas Solenoid Valves Certified EN161.
A gas solenoid valve or gas safety shut off valve is an electro-mechanical valve designed for the open and fast closing control for Natural Gas, Propane Gas, Coke Oven Gas or Biogas systems and equipment. Gas approved single stage solenoid valves are certified to EN161 Class A gases to ensure reliability and closure for pressures typically ranging from 0 to 200 millibars, although there are options for gas pressures up to 360 millibars and 6 bar.
Typical applications for gas solenoid valves include gas power burners, atmospheric gas boilers, industrial kilns, gas powered generating stations, commercial gas cookers and appliances in schools, hospitals, retirement homes and many other applications where gas supply lines need additional security and protection.
Auto Reset Gas Valves - Normally Closed (Fast failsafe closed with power off) - Electrical Power will Open (Models VMR + VMH)
Manual Reset Gas Valves - Normally Closed (Failsafe closed with power off) require Manual resetting or lifting back into the open position combined with electrical power to keep the valve open. (Model EVRMNC). Designed for industrial applications where engineers need to verify the system is safe before the main gas inlet valve can be manually reset or lifted back into the open position. For situations where an electrical power failure causing gas valve closure and loss of flame could if reopened could fill the area with an explosive gas mixture.
Gas EN161 Solenoid Valves: Auto Reset Model VMR
VMR Gas solenoid safety slam shut valves - Auto reset normally closed require electrical power to open.
Pressure Standard 0 to 200 millibars, optional 360 millibars or 6 Bar.
Coil: IP65 optional ATEX for zones 2 and 22 according to 94/9/EC directive.
Media: Air and non-aggressive gases included in the 1, 2 and 3 families to EN437, Special versions available for Biogas and coke oven gas (COG).
Motor Actuated Gas Valves EN161 (Electro-Hydraulic) - Auto Reset
The Elektrogas VMH is a gas safety shut off valve with hydraulic actuator suitable for air and non-aggressive gases included in the 1st, 2nd and 3rd gas families to EN437 for gas blocking and releasing control. Require electrical power open with power off will quickly slam shut closed; Certified EN161 and Class A for natural and propane gas.
Pressure: 0 to 200 through to 1600 Millibar depending on model - see below.
Incorporates fine 600 micron mesh filter that protects valves eat and disc and downstream equipment, fitted with G1/4 pressure gauge on both inlet and outlet chamber to connect pressure gauges, pressure switches, leakage tester or other gas equipment. Actuator is provided with ISO4400 DIN43650A IP65 EN60529 plug for easy cabling.
Connections flange PN16 ISO7005 from DN65 to DN300.
Optional Ex-proof for zone 2 according to ATEX directive 94/9/EC.
Manual Reset Gas EN161 Solenoid Valves
Gas safety slam shut off solenoid valves with manual reset series EVRM-NC EN161 Group 2 Certified for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN437) with special versions available for aggressive biogas's and coke oven gas (COG).
Require electrical power ON and manual resetting or lifting into the open position to allow flow, electrical power will only keep valve in the open position. When power is removed, the valve will quickly slam shut closed and stay closed until electrical power is restored, and the valve manually reset into open position.
Designed to prevent gas valves from automatically reopening after a power cut, so an engineer can verify that the pilot light is lit before manually resetting the valve into the open position.
Optional Ex-proof ATEX 2014/34/EU directive for hazardous area zones 2 and 22.
Includes fine filter mesh to protect NBR based rubber seal (EN549), seat and downstream equipment from debris and foreign particles.(Except brass models).
Includes G1/4" pressure gauge ports on two sides (both inlet and outlet chamber) to connect pressure gauges, pressure switches, leakage tester or other gas equipment. (Except brass models).
Includes G1/8" connection to fit closed position indicator switch or visual indicator.
