Wholesale Mada M16RMN.C original proof normally closed gas emergency shut-off safety valve

Features M16 / RM NC series valve is a normally closed solenoid valve. 1. The valve is normally open state in their daily work, the solenoid valve coil is energized. 2. When the accident occurred, the instantaneous power valve coil spring through the internal mechanism of the rapid reaction force to close the valve. In this case, even if energized, the valve is still closed. 3. When the workers finished dealing with incidents, give the coil is energized, then manually re-open the valve, the gas supply would be restored.

Valves open and close Identification: DN65 ~ DN300 diameter electromagnetic valve is OPEN arrow with manual reset valve head screw (hexagonal pattern) on the (open) to identify whether as a horizontal line, if compared to a horizontal line valve is open, Otherwise, the valve is closed. (As shown): parameters Technical parameters: Control type: direct-acting operation structure: Diaphragm seal valve seat adapt to temperature: -20 ℃ - + 60 ℃ Medium temperature: ≤80 ℃ sealing material: NBR dingqing rubber Maximum Working Pressure: 0 ~ 500mbar; 0 ~ 6bar Body Material: die-cast aluminum alloy Nominal pressure: PN16 Medium: gas, natural gas, liquefied petroleum gas and other non-corrosive gases Connection: threaded connection (1/2 "-2"), in line with EN10226 standard flange interface (DN40-DN300) to ISO 7005 standard closing time: <1 second (approximately 20 milliseconds) supply voltage: DC12V, DC24V, AC220V / 50HZ Open: Manual Reset Voltage Tolerance: -15% - +10 % electric power: Table proof grade: EExmIIT4 Electrical connection: plug-in (regardless of positive and negative) Housing protection rating: IP 65 metal inner parts: stainless steel and brass installation specifications and precautions: 1. usually installed in the indoor surveillance zone on the main supply pipe. 2. The pipe cleaning or purged, as there is solid contaminants in the media, it is recommended to install a filter on the valve before the pipeline. 3. strict installed in accordance with the valve body the subject of the gas flow direction. 4. Recommends that the valve stem mounting horizontally or vertically (as shown). 5. When the solenoid valve open-air installation, you must install a protective cover, in order to ensure the performance and extend its life. 6. When the solenoid valve coil energized to work, non-covered or removed to prevent overheating. 7. The solenoid valve coil, plug-ins and connections, non-hitting impact, to avoid damage. 8. When the solenoid valve coil charged normal work, due to self-heating, high temperature, do not touch. Gas Equipment Co., Ltd.
