Valve Working Animation：Pneumatic Angle Seat Valve

The pneumatic angle seat valve is a fluid control valve that uses compressed air as the power source to drive the opening and closing of the valve core through a pneumatic actuator. It is widely applied in the fluid control systems of chemical, pharmaceutical, food, environmental protection, water treatment and other industries for regulating and controlling the flow rate, pressure and direction of fluids. Meanwhile, it is also extensively used in industrial automation systems, such as material conveying on production lines and waste gas treatment.

Main Structure of Pneumatic Angle Seat Valve

• Valve body: Made of high-quality cast material with compact structure, corrosion resistance and high strength. The streamlined design of the valve body inner cavity reduces fluid resistance and improves flow capacity.

• Valve core: Manufactured from wear-resistant and corrosion-resistant material to ensure long-term stable operation. A soft sealing structure is adopted between the valve core and valve seat, featuring excellent sealing performance and zero leakage.

• Pneumatic actuator: Composed of cylinder, piston, spring and other components. It drives the piston movement through compressed air to realize the opening and closing of the valve core. An adjusting bolt is installed on the outside of the cylinder for convenient adjustment of the actuation speed of the pneumatic actuator.

• Positioner: Used to indicate the on-off position of the valve core for easy operation and maintenance.

• Connecting flange: Compliant with international standards for easy connection with other pipelines and equipment.

Working Principle of Pneumatic Angle Seat Valve

When compressed air enters the cylinder of the pneumatic actuator, it pushes the piston to move and then drives the valve core to move. The valve core closes when compressed air acts on one end of the piston, and opens when compressed air acts on the other end of the piston. The on-off control of the valve can be achieved by changing the flow direction of compressed air.
