1.25″ Inch Pneumatic Air Operated Ball Valve Double Acting

WIC Valve PVD series 1-1/4″ NPT pneumatic air actuated valve equipped with a stainless steel 3-piece ball valve, it allows a easy installation.  PVD series double acting air actuated valve use pressurized air to open and close the ball valve. The characteristic of the air actuated ball valve is that it has high flow rate, the full port straight through ball valve allows the service media such as air, gas, liquid, steam and water flow through directly without reducing the flow speed.  The 316 stainless steel ball valve comes with Teflon seal which can be used at a high operating temperature and pressure applications.  Ideal for the hazardous environments.

Double Acting Air Actuator Structure:

1. Indicator: Position indicator with NAMUR mounting standard.

2. Pinion: High precision piston is made by nickelled alloy steel.  Fully conform with ISO5211, DIN3337 and Namur.

3. Actuator Body: Extruded aluminum alloy ASTM6005 body.

4. O-Rings: High quality NBR (Buna-N)

5. Pistons: Die-casting aluminum twin rack pistons are treated with hard anodized.  Symmetric mounting position that ensure a fast operation and long cycle life.

6. Travel Adjustment bolts: Two independent external travel adjustment bolts allow ±5° adjustment for both open and close directions.

7. End Caps: Die-casting aluminum powder polyester.

8. Bearing & Guides: Made by low friction compound material to minimize the direct contact between metals.

 

PVD Series Double Acting Air Actuator Operating Principle:

Pressurized air is introduced to Port A that forces the pistons outward.  It causes the pinion to turn counterclockwise while the air is being exhausted from Port B (See Drawing 1)
