12 and 24 vdc solenoid powered diesel engine shut down valves based on the standard 3" and 5" slimfit Chalwyn butterfly valves. Designed for applications where no suitable electrical supply is available during engine start up and a manual override facility is therefore required. Once the protected engine is running and electrical power is available the valve is latched in the open (run) position by the solenoid until power is lost or until the manual emergency shut down facility is operated. These valves are available in flange mounted form or can be supplied fitted with hose adapters and/or a flametrap housing.
Versions of these valves are available for both hazardous and non-hazardous area application. Valve bodies and discs are manufactured in corrosion resistant hard anodised aluminium with PTFE coating. The valve spindle is made from 316 grade stainless steel.
