The types of concealed stem gate valves mainly include wedge-type single gate, elastic gate, double gate and parallel gate. The main difference between these types lies in the shape and structure of the gate, which affects its sealing performance and applicable scenarios.
Wedge-type single gate: This type of gate valve uses a wedge-shaped gate, which achieves better sealing effect through the wedge design and is suitable for occasions that require high sealing.
Elastic gate: The elastic gate has good elasticity and can adapt to changes in medium pressure to a certain extent. It is suitable for occasions that require a certain adjustment ability.
Double gate: This type of gate valve adopts a double gate design, which increases the reliability of sealing and is suitable for high pressure and high temperature occasions.
Parallel gate: The parallel gate has a simple design and a flat sealing surface. It is suitable for general industrial pipeline systems and is easy to maintain.
These different types of concealed stem gate valves are different in structure, but the common feature is that the valve stem is hidden inside the valve body, and the valve stem is driven up and down by rotating the handwheel to achieve the opening and closing of the valve.
