VA Series "Valve + Actuator" On-Off Valves

Fast Acting,High Cycle with No External Moving Parts; Connections (3/8" to 2")


The VA and VIP series coaxial valves are undergoing a minor design change.

The NAMUR pad is being eliminated in order to reduce the weight and material used. An adapter plate is available to provide a NAMUR mounting pad. During this transition there will be a period of time where some sizes are the new design and others are the old. If this is a critical matter for you, please call 1-800-899-0553 to verify what design is in stock for the size that you need.

See the details on this design change.

VA Series Compact On Off Valve



The VA Series combines a pneumatic actuator and fast on-off control valve into one body, eliminating packing glands, actuators and mounting kits. There are no exposed moving parts, eliminating pinch points and increasing operator safety. Since the actuator is part of the valve, costs are greatly reduced when compared to standard actuated valves. Operating life has been tested to well over 1,000,000 cycles, the balanced design reduces friction and wear. The stroke is linear and parallel to the flow, dramatically reducing the required force to close or open the valve. The internal waterway design was designed for optimum flow characteristics.
