Stainless Steel Corrosion Resistant Flange Steam Plastic Head Pneumatic Angle Seat Valve
Stainless Steel Corrosion Resistant Flange Steam Plastic Head Pneumatic Angle Seat Valve is an automated valve designed for high-temperature steam control. Its plastic actuator head reduces weight and corrosion risk, while the flange connection ensures secure installation and reliable, hygienic operation in industrial systems.
Working Principles

The working principle of a Stainless Steel Corrosion Resistant Flange Steam Plastic Head Pneumatic Angle Seat Valve involves controlling the flow of high-temperature steam through an angled seat using a pneumatic actuator with a plastic head. When compressed air is applied, the piston inside the actuator moves, lifting the valve plug from the seat and allowing steam to flow smoothly through the valve. The angled seat minimizes flow resistance and ensures efficient discharge. Releasing or reversing the air pressure returns the piston, pressing the plug firmly against the seat to form a tight seal and prevent leakage. This design provides precise, automated control, lightweight operation, and reliable performance in corrosive and high-temperature environments.
