Industrial gate valves are primarily selected for full-open or full-closed pipeline isolation with low pressure loss. WDL Valve supplies wedge, slab, expanding, through-conduit, knife, cryogenic and forged-steel gate valves for oil, gas, chemical, power, water, slurry and marine applications.

Selection guidance: Gate valves are not normally recommended for continuous throttling because partially open operation can damage the gate and seats. Select the design according to medium cleanliness, solids content, pressure differential, temperature, required bore and operating frequency. Knife gate valves suit slurry and fibrous media, while wedge and through-conduit designs are commonly used for industrial and pipeline isolation.

Standards and RFQ data: Available designs can follow applicable API 600, API 602, API 6D, ASME B16.34, API 598 and project specifications. For quotation, provide size, class or PN rating, body and trim material, seat type, medium, temperature, end connection, stem arrangement and actuator requirements.
