Basic PVA System

The EZE Turn PVA can be used on any multi-turn valve independent of type or size.

Specifically, valves that are large and require a tremendous amount of force to operate manually can now be operated rapidly, reliably and safely. The speed of operation of any valve can be selected without constraint of space or the limitations associated with the number of workers that can stand around to operate a hand wheel.

Worker Injuries
The manual operation of valves is a common cause of worker injury, especially where there are old valves that require excessive amounts of force to operate. Many valves can have 300 to 400 turns from open to close. Extreme force coupled with repetitive motion can cause:

• Strained Backs
• Sore Muscles
• Pinched Nerves
• Dislocated Joints
• Ruptured Disks
• Heat Stroke
• Broken Bones
• Fatigue

The Portable Valve Actuator is ready for use after installing a standard drive plate onto your existing valve’s handwheel. This plate is specifically designed to work with the PVA. It installs easily to the spokes of the handwheel with two U-Bolts. Now simply supply the actuator with clean lubricated air and you’re ready to turn your valve.

Safety
The actuator’s trigger (located midway on the actuator) and speed control (located at the air inlet) are both spring return fail closed. Both must be engaged for the actuator to turn. Releasing either the trigger or speed control during operation will stop the actuator. The speed control allows the operator to move the valve at their own comfort level. The forward and reverse switch is located directly opposite from the trigger. Forward turns the actuator in the clockwise direction, and reverse turns the actuator in the counter-clockwise direction. The EZE Turn PVA is pneumatic, so there is no concern of electrical shock or operating in explosive atmospheres.
