This valve opens when de-energised. Check that this behaviour is appropriate for the chamber and process before specifying it. It does not provide the combined pump isolation and venting function of SECUVAC. Confirm the vent gas, venting rate and electrical supply in the 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.

Explore the Leybold LEYCON vacuum valves and Leybold brand guide. Compare vacuum gauges and controllers, plan gauge calibration, or discuss servicing.
For LEYCON DN10 Power-Failure Venting Valve, include working pressure, required flow or chamber volume, gas and vapour load, operating hours, electrical supply and connections. For a replacement, send the complete nameplate and serial number so the configuration can be checked.
