gate valve factory, gate valve company stainless steel gate valves manufacturers Gate valves are used to cut off or connect media transmission, and are suitable for pipeline systems in petroleum, chemical, thermal power plants and other industrial fields. Gate valves can only be fully opened and disconnected in the pipeline, which means it cannot be used for regulation and throttling. Gate valve provides well on/off or shuts off features, pressure drop during operation is very less, and is bidirectional. Meanwhile as metal to metal seat, these valves can respond to specific operating high pressure, high temperature operating conditions. The Details of Gate Valves Metal Seated Gate Valve Full Port Gate Valve Handwheel Gate Valve Horizontal Gate Valve Industrial Gate Valve Advantages 1. Flexible or solid wedge 2. Full-bore or reduced-port 3. Replaceable seat or integral seat 4. Bolted bonnet or self sealing bonnet 5.
