Rotating the handwheel drives the valve stem to lift, making the valve disc fit/separate from the valve seat to control fluid on-off. It can also adjust the valve disc opening slightly to regulate flow.
Made of WCB carbon steel, it uses flanged connection for easy installation and maintenance, with excellent sealing performance. Suitable for medium-low pressure working conditions, it is widely used in pipeline systems of petrochemical, water supply and drainage, power industries, and applicable to scenarios requiring precise on-off or small-range flow regulation.
