4 Inch Pneumatic Rotary Valve Actuator Quarter Turn
Wafer Pneumatic Butterfly Valves with High Performance Pneumatic Actuator
Basic information
1. Preloaded coating springs are made from the high-quality material for resistance to corrosion and longer service life, which can be demounted safely and conveniently to satisfy different requirements of torque by changing the number of springs.
2. ISO5211 standard for ball valves or butterfly valves.
3. DIN3337 and NAMUR Standard for pneumatic accessories.
4. Twin rack pistons are made from die-casting aluminum treated with hard anodized or made from cast steel with galvanization, symmetric mounting position, long cycle life and fast operation, reversing rotation by simply inverting the pistons.
5. It has a number of springs inside and will auto return once air is interrupted and it could keep the valve and project safe.
