Angle Seat ValveApplications
AS angle seat valve is a pneumatic valve. It is widely used in food and chemical processes, sterilization machines, high pressure sterilizers, dry-cleaning machines, clothes dryers and beer equipment, especially in steam piping systems and production lines.
Operating Principle
The operating principle of AS angle seat valve is the same as the check valve. However, the Y-shaped valve body equipped with pneumatic actuator expands the flow cross section of the valve chamber. This makes the fluid steadier and increases the flow rate by 30%. Meanwhile, the flow direction of medium is changed, and smaller pneumatic actuator can be equipped.
