Assured Automation, Clark, N.J., USA, now offers an oxygen cleaned nickel plated brass coaxial valve for OEM's of oxygen generators. The compact, high cycle, low cost VA Series valve is ideal for saving space compared with other valve designs. The VA Series is currently being used successfully by several large OEM's in Europe.
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 with standard actuated valves. Operating life has been tested to well over a million cycles, due to the balanced design that reduces friction and wear.
