Double Acting Pneumatic Valve Actuator Rotary

Pneumatic Actuator

Feature of Pneumatic Valve Actuator:

● 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.
● ISO5211 standard for ball valves or butterfly valves.
● DIN3337 and NAMUR Standard for pneumatic accessories.
● 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.
● It has a number of springs inside and will auto return once air is interrupted and it could keep the valve and project safe.

Main Features

1. Dual piston rack and pinion design for compact construction,symmetric mounting positon,high-cycle life and fast opeation,reverse rotaton can be accomplished in the field by simply inverting the pistons.
2. Multiple bearings and guides on racks and pistons,low friction,high cycle life and prevent shaft blowout.
3. Modular preloaded spring cartridge design.with coated spring for simply versatile range,greater safely and corroson resistance, longer cycle life.
4. Fully machined teech on piston and pinion for accurate low backlash rack and pinion engagement,maximum efficiency.
5. Stainless steel fasteners for long term corrosion resistance.
6. Fullconformance to the latest specification;ISO5211.DIN3337 and Namur or product interchange ability and easy mounting of solenoids, limit switches and other accesories.
