1" InchPneumatic Stainless Steel Industrial Air Actuated Ball ValveDouble Acting (Air Return)
PVD series 1" 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 pressurizedair 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. Also, it is ideal for the hazardous environments.

1. Indicator: Position indicator with NAMURmounting standard.
2. Pinion: High precision piston is made by nickelled alloy steel. Fully conform withISO5211, 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 Air Actuator Operating Principle:
Pressurized air isintroduced to Port A that forces the pistons outward. It causes the pinion to turn counterclockwisewhile the air is being exhausted from PortB (SeeDrawing 1)
