Gas Valves
Gas valves in this category are the safety and control valves used in industrial and commercial gaseous-fuel systems — burners, boilers, ovens, furnaces and gas-train assemblies — where uncontrolled gas flow presents a fire and explosion risk and the valve forms part of a safety chain. The central type is the automatic safety shut-off valve: a normally-closed valve, usually solenoid- or motor-operated, that opens only on a safe command and closes quickly and reliably on loss of signal, fault or power.
In Europe these valves are governed by EN 161 (automatic shut-off valves for gas burners and gas appliances), which sits within the EN 13611 framework of safety and control devices for burners and appliances. EN 161 sets construction, leak-tightness, endurance and closing-time requirements and defines classes (for example by closing time and function) that determine where a valve may be used in a burner's safety logic, including the control-function level needed for the shut-off duty.
Designs include single and double (two-in-one) solenoid shut-off valves, slow-opening and fast-closing variants, and manual ball or plug cocks for isolation. Bodies are typically aluminium or brass/steel for the pressure and gas family (natural gas, LPG, town gas), with NBR or FKM seals compatible with the fuel, threaded or flanged ends, and pressure ranges spanning low- to medium-pressure gas service.
Selection is driven by gas type, flow and inlet pressure, required closing time and the appliance's safety classification rather than the heavy process-valve codes. Himalay's MSME partners manufacture gas valves with leak and functional testing, material and seal compatibility documentation, and EN 161 / EN 13611 certification coordinated where specified and partner-dependent, with PED-CE (EU), SABER (Saudi Arabia) and destination-market gas approvals arranged as part of the standard order flow.
