Product Overview
The WCB Wedge Gate Valve is a commonly used isolation valve that controls the flow of media by lifting or lowering a wedge gate. The sealing is achieved through the pressure of the medium, which forces the gate tightly against the seat, ensuring effective shut-off. This structure makes the valve suitable for fully open or fully closed conditions rather than throttling applications.
In practical use, the WCB Wedge Gate Valve can be manufactured with rigid or elastic wedge designs. The elastic wedge helps compensate for minor machining deviations and improves sealing performance under varying temperature and pressure conditions.
Structure & Working Principle
Our WCB Wedge Gate Valve adopts a rising stem design, allowing operators to visually identify the open/close position. When the handwheel or actuator is operated, the stem drives the wedge gate vertically, creating a straight-through flow path with minimal resistance.
- Full bore design reduces pressure drop
- Bidirectional sealing performance
- Stable sealing under high pressure conditions
Product Features
- Compact body structure with smooth internal flow channel
- Sealing surfaces use stainless steel or hard alloy for durability
- Flexible graphite packing ensures stable sealing and easy maintenance
- Multiple actuation options: manual, electric, pneumatic, and gear
- Suitable for water, steam, and oil pipeline systems
