About the Wedge Gate Valve
The wedge gate valve is the industry-standard isolation valve for most on-off service applications in oil & gas, petrochemical, power, water treatment, and general process piping. Its robust design - a wedge-shaped gate that descends into twin body seats to block flow - delivers full-bore, unrestricted flow when fully open (zero pressure drop), making it ideal for applications where throttling is not required.
Three wedge configurations are available: solid wedge (simplest, most robust; suited to most fluids), flexible wedge (single-piece gate with peripheral relief groove that flexes to compensate for seat misalignment under thermal cycling), and split wedge (two-piece gate that self-adjusts to seat faces; preferred for sticky or non-lubricating fluids). Non-rising stem designs are used in underground or space-constrained installations; rising stem designs give instant visual position indication.
Vajra Industrial Solutions supplies wedge gate valves to API 600 (large bore, ≥2"), API 602 (small bore, ≤1.5"), API 603 (stainless steel), and API 6D (pipeline) standards in sizes 1/2" to 36" and pressure classes 150 through 1500. Body materials span Cast Iron, Ductile Iron, Carbon Steel WCB/WC6/WC9/P91, and Stainless Steel CF8/CF8M. All trim numbers to API 600 (Trim 5, 8, 12, 13) are available with Stellite hard-facing for erosive or high-temperature service. Hydrostatic test certificates per API 598 are provided.
Where It's Used
Key industries and applications for the Wedge Gate Valve
Oil & gas production and transmission
API 6D solid wedge gate valves for pipeline isolation, wellhead, and gathering system service in carbon steel WCB (Class 150–600) or LTCS LCC for cold climates
Power plant steam systems
Class 600–900 alloy steel WC6/WC9 parallel slide or flexible wedge gate valves for main steam, hot reheat, and boiler feed water applications up to 540°C
Refineries
rising stem gate valves in Trim 8 (HF acid service: Alloy 20 body + Monel trim) or Trim 12 (Stellite faced) for crude, vacuum gas oil, and high-temperature process streams
Water treatment and distribution
resilient-seated DI gate valves to AWWA C500/C509 in sizes 3"–24" for municipal water mains, sewage lift stations, and fire protection systems
Chemical and fertilizer plants
SS316 gate valves for acidic, alkaline, and corrosive process streams; bellows-sealed versions for fugitive emission control to ISO 15848-1 / TA-Luft
How to Choose the Right Wedge Gate Valve
Gate valves are the correct choice for pure isolation service where the valve will be either fully open or fully closed. Never use a gate valve for throttling - partial opening causes wire drawing (erosion) of seats and gate, leading to premature failure. Select rising stem for above-ground installations where visual position indication is needed; non-rising stem for underground, vault, or headroom-limited installations. Choose alloy steel WC6 or WC9 body for service above 425°C.
