the giuliani anello emergency shut-off valve 

 The MSV and MSV/6B are normally open solenoid valve, the valve normally open state processing work, the solenoid valve coil is de-energized to open the valve and keep working, you need to manually reset. 

 The main technical parameters 

 - Connection: threaded connections UNI ISO 7-1; flange connection ISO7005 / 2 

 - Maximum inlet pressure: 0.5bar (MSV); 6bar (MSV/6B). 

 - Power supply: 230V/50HZ, 24V/50HZ and 12V DC, 24VDC only for flange, connection type 

 - Turn off time: <1 S. 

 - Fuel: three types of gas (city gas, natural gas, liquefied petroleum gas), non-corrosive gases 

 - Material: aluminum body and the valve cover; stainless steel spring; steel piston; NBR rubber gaskets and O-rings; other parts of the material as well as brass, aluminum, plastic and galvanized pipe. 

 Gas emergency shut-off valve reset: reset valve is completely manual, the purpose is to find the reasons of emergency troubleshooting manual reset. In order to simplify the reset function, all MSV/6B series and all flange type MSV series valves are installed double breaker, so that you do not need to install a bypass system downstream pipeline electromagnetic. 

 When the valve is reset, unscrew the aluminum knob to release the gas pressure, and then the the aluminum knob turned Shunfa needle rotation inside, mentioning reset by hand, completely eliminating the need for installation of bypass system before you can use special tools reset trouble. 

 And gas pipeline marked on a red circle and a green circle, allows the user to clearly know the switching status of the solenoid valve. 

 If double breaker solenoid valves must be operated in accordance with the instructions in each package, only one circuit breaker the MSV series of products, you should aluminum knob advancing solenoid valve on the gas pipeline. 

 The the the MSV Model No.: MSV12, MSV15 MSV34 MSV100 MSV100/6B MSV114 MSV200 MSV212 MSV300, MSV400, MSV500, MSV600 
 The the MSV/6B Model: MSV12/6b MSV34/6B MSV100/6B MSV112/6B MSV200/6B MSV212/6B MSV300/6B MSV400/6B MSV500/6B, MSV600/6B.
