Expanding Slab Gate Valve

Expanding Slab Gate Valve is a type of slide valve that utilizes parallel gate plates as its closing mechanism. These plates are equipped with a spreading mechanism to enhance functionality. The force pressing the plates against the valve seat is regulated by the medium pressure acting on either a floating gate plate or a floating valve seat. In dual gate flat gate valves, the inter-plate spreading mechanism provides additional pressing force. This valve is designed with innovative features including low operating torque, rapid actuation, minimal vibration, extended operational life, and enhanced safety. It is mainly used for the isolation or venting of gases and liquids in pipeline systems.…

Features & Benefits

●The valve features two parallel gate plates and a wedging device, updating the traditional single gate plate design.

●Sealing elements are designed as separate components, which prevents deformation from thermal expansion and temperature differences, ensuring a reliable seal.

●The materials used for the sealing components are resistant to wear and corrosion, enhancing the valve's longevity.

●It is equipped with a bidirectional forced sealing capability, which simplifies operations and ensures a dependable seal.

●The fully enclosed design of the valve provides excellent protection, allowing for operation in all weather conditions.
