VMH912 Flanged PN16 group 2 back pressure sealing compliant DN300 12" 2/2 way Normally Closed EN161 Class A Gas Approved Aluminium 0 to 600 mBar Motorised Gas safety shut off valve with PCS CPI closed position indication feed back switch. The VMH912 series gas valve is a safety shut off valve for gas with hydraulic actuator and are suitable for air or gas blocking and releasing controls, required in the main pipe of gas power burners, atmospheric gas boilers, industrial kilns and others gas consuming equipment.
Suitable for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN 437), special versions for aggressive gases. The valve is open only when energized: if, for any reason, power supply goes down, the valve closes immediately (intrinsic safe), Qualified for continuous service (100% ED). An incorporated fine mesh filter protects the valve seat and disc as well as downstream components and prevents dirty contamination.
Provided with G1/4 pressure gauge on two sides in both inlet and outlet chamber to connect manometers, pressure switches, leakage tester or other gas equipments.
The actuator is provided with ISO 4400 plug for easy cabling. The protection class is IP65 (EN 60529). If compressed air is available, the hydraulic actuator can be replaced with a pneumatic one (VMP series).
All components are designed to withstand any mechanical, chemical and thermal condition occurring during typical service. Effective impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and resistance to corrosion of the components. Valves are 100% tested and fully warranted.
