Industrial gate valves are suitable for both above ground and underground installation and are designed for fully open or fully closed service. They are installed in pipelines as isolating valves and should not be used as control or regulating valves.
These valves can be divided into two main types, namely parallel and wedge-shaped. Parallel industrial gate valves use a flat gate between two parallel seats. The knife gate valve is a popular valve designed this way, with a sharp edge on the bottom of the gate. Wedge-shaped industrial gate valves use two inclined seats and a slightly mismatched inclined gate.
Industrial gate valves used to be a metal seated wedge with the conical wedge design and angular sealing devices needing a depression in the valve bottom to ensure a tight closure. These days resilient seated gate valves have a plain valve bottom that allows for the free passage of sand and pebbles in the valve.
Rising stems are fixed to industrial gate valves and raise or lower as the gate is operated. This is a visual indication of the industrial gate valve’s position and this makes it easier to grease the stem. This type of industrial gate valve is usually only suited to above-ground installations.
Non-rising stems are threaded into the gate itself and take up less vertical space. These valves are suitable for both above ground and underground installations.
Industrial gate valves are long-lasting and durable and don’t require much maintenance.
