Design features
structural stiffness and guided travel designed for high-flow, large-bore isolation
Final dimensions, materials, ratings and documentation depend on the approved configuration.
Gate valves / LIANGGU
Large Diameter Gate Valve
This model is a gate valve distinguished by structural stiffness and guided travel designed for high-flow, large-bore isolation. For a project quotation, share the required size, pressure designation, materials, seating, connections and quantity. Final suitability is confirmed against the approved specification.
PRODUCT DETAILS
Understand this valve.
Working principle
a stem moves a wedge or parallel gate clear of the bore for isolation; the valve should normally be fully open or fully closed, not used as a routine throttling device; verify operating time and foundation support
Typical applications
cooling-water networks, intake systems, transmission pipelines, and plant-wide utility mains
Selection priorities
bypass need, operating time, foundation support, actuator torque, site lifting constraints, and line load
