VAX Series High Pressure Coaxial Valves

VAX Series coaxial valves have been proven in the control of vacuum and gaseous, liquid, gelatinous, highly viscous and contaminated media. Coaxial valves are suitable for a very broad variety of applications and exceed expectations even under the harshest conditions.

The design of the valves allows high flow rates to be controlled even at zero or full pressure drop. The VAX...E or VAX...P series are available in 2/2-way and 3/2-way versions with threaded ports. They feature complete pressure balancing - pressure drop has no effect on the valves switching characteristics.

The VAX...E series (Electric) are double acting solenoid valves
The VAX...P series (Pneumatic) are controlled with compressed air or inert gas
