The Sapphire Gas Solenoid Valves from DMS are a Safety Valve controlled by a Solenoid. The standard version is a Normally Closed design that would shut off in the event of power being lost to the valve in order to impede the flow of gas. The loss of power can be down to a fire alarm or gas detection alarm. All of the Sapphire Valves are spring loaded so once the coil releases the valve, it closes rapidly to ensure fast operation. Once power is reconnected they will re-arm themselves automatically to allow gas to pass through again.
The standard power requirements for the Sapphire Valves is a 230v mains connection with the option of a 24vdc coil available. CPI (Closed Position Indicators) can be offered as an optional requirement as well should an application call for it. The sizes of valves are available as 15mm up to and including 50mm with a BSP Female threaded connection and then from 65mm up to 150mm a PN16 Flanged connection is provided.
The Sapphire Valves can be used with Natural and Liquefied Petroleum Gases as standard with a maximum operating pressure up to 360mbar for all models. Horizontal and Vertical installation are both permissable but the coil itself must not be pointed downwards.
