UHV LEAKVALVE - HIGHLIGHTS

The core of this valve is a diaphragm in stainless steel 316L, gold plated.
Robust, it cannot be damaged with any normal methods.
The dead volume is kept as small as possible. There is no narrowing before or after the valve seat. Flow direction is freely eligible.
A direct actuator adjusts the sealing force in very high resolution. Quick, stable leak and reliable.
While baking out, the stepper motor and the NC-actuator remain on the valve. Full control during bakeout periods.
10 seconds operating time (stepper motor driven) for the whole control range.
A heating cartridge is available as an accessory. It heats where it is needed: Very close to the valve seat.
A pneumatic actuator NC is responsible for fast actuation. The open position can be adjusted by hand over the whole range.

This product is available with CF-16, CF-35 (all rotatable), or with VCR female.

A fulI program of actuators is available: Manually operated, stepper motor driven including Controller (input 0-10V or RS-232, or manual mode), pneumatically operated NC with adjustable open position.

A visual position indicator on the top of the motor actuator shows the actual position.

In case of power cut the Controller saves the actual position and recognises it when power returns. Repeated calibration is not necessary.
