High Flow Compact Pneumatic Control Angle Seat Valve with NPT Thread
This compact pneumatic control angle seat valve is designed for high flow applications and features advanced piston sealing with a position indicator. It includes an NPT thread connection, ensuring secure and reliable installation. The valve offers a 360° rotatable pilot connection, allowing for flexible installation in any position. Capable of handling neutral gases and air, it provides a high cycle life and superior performance compared to traditional ball valves.
Types and Working Principles
Single Acting Valve (Spring Return): The single acting valve, available in normally open or normally closed configurations, relies on a spring to return to its default position. Its pneumatic head typically features a single hole, and the operation is controlled by the spring, which dictates the opening and closing of the valve based on the air supply.
Double Acting Valve: The double acting valve generally has two holes in its pneumatic head and is directly controlled by the air supply for precise switching. For enhanced accuracy, a combination of double acting and spring return can be selected according to customer requirements.
Key features include:
- High Flow Rate: Ensures efficient operation for demanding applications.
- NPT Thread Connection: Provides a secure and reliable connection.
- Position Indicator: Offers clear visual feedback on valve status.
- 360° Rotatable Pilot Connection: Allows for flexible installation options.
- Durable Construction: Designed for a high cycle life, outperforming traditional ball valves.
This valve is ideal for applications requiring reliable and efficient pneumatic control, with customizable configurations to meet specific needs.
