Description: Solenoid valves are either gas or petrol based. Gas solenoid is used as On/Off valve that filters the LPG impurities (i.e. magnetic and duet). Life of the filter is 50,000 km. The valve cuts off the flow if there is any leakage of LPG. Petrol solenoid is normally in open condition and allows flow of petrol when/vehicle runs on petrol and shuts off when vehicle runs on LPG with manually shutoff.
