Leybold LEYCON EV 016 DOS AB Dosing Valve

Product details

Applications and selection

The Leybold EV 016 DOS AB is a manually adjusted dosing valve for controlled gas admission into a vacuum system. Its DN16 ISO-KF connection suits laboratory and process gas-inlet arrangements requiring fine flow adjustment.

Key specifications

Documented configurations

Meter gas flow into the vacuum system

The dosing range is gas throughput in mbar l/s, not pumping speed in l/s. Select the valve with the available upstream pressure, gas species and required throughput. The fitted filter changes maximum flow; alternative filters and fittings are selected separately. Use appropriate upstream isolation and the manufacturer’s adjustment procedure.

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.
