System protection and restart
The isolation and venting functions have different leak specifications. The housing leak figure must not be used as the valve-seat rating. Install in the indicated flow direction and follow the pressure-equalisation requirements: the manufacturer lists opening below 150 mbar differential and closing above 150 mbar differential. Confirm suitability where another inlet safety valve is already fitted.
Materials, installation and enquiry
Confirm gas compatibility, cleanliness, working and bakeout temperature, flange standard, mounting orientation and pressure difference before selection. A nominal flange size alone does not establish compatibility. Request connection hardware, controls and spares explicitly; accessories are included only where specified in the quotation.
For valve selection, send the line size, pressure range, gas or process, required fail position, actuation supply and switching duty. For replacements, include the complete valve nameplate.
