Stainless Steel Flange Steam Valve Plastic Head Manual Angle Seat Valve
Stainless Steel Flange Steam Valve Plastic Head Manual Angle Seat Valve is a manually operated valve designed for controlling steam flow. Its angled seat ensures smooth discharge, while the plastic handwheel offers lightweight, ergonomic operation and the flange connection provides secure installation in industrial systems.
Working Principles

The working principle of a Stainless Steel Flange Steam Valve Plastic Head Manual Angle Seat Valve involves manually controlling steam flow through an angled seat using a hand-operated plastic head. Turning the handwheel rotates or lifts the valve stem, moving the plug away from the seat to allow steam to pass through the valve. The angled seat minimizes flow resistance and ensures smooth, efficient discharge. Closing the valve presses the plug firmly against the seat, forming a tight seal to prevent leakage. This manual operation provides precise control of steam flow, safe handling in high-temperature environments, and reliable performance without the need for external power or pneumatic systems.
