Gate valves / LIANGGU
Stainless Steel Gate Valve
This model is a gate valve distinguished by pressure parts in corrosion-resistant grade for clean or aggressive service. 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 chloride exposure and seat overlay
Typical applications
chemical processing, water treatment, food-related utilities, and corrosive plant services
Selection priorities
the stainless grade, chloride exposure, seat overlay, packing formulation, and cleaning requirement
