Blaze Expanding Gate Valve | 4-1/16" | 5K | WKM-Type
Overview
The Blaze Manual Expanding Gate Valve, 4-1/16", 5,000 PSI (5K), WKM-Type, is designed for reliable mechanical sealing in production and surface flowline operations. Its expanding gate mechanism applies outward mechanical force on both upstream and downstream seats, enabling positive sealing even when line pressure is low or unstable—an advantage over slab or FC-style valves.
Constructed from forged alloy steel and built to common industry practices for WKM-style valves, this large-bore expanding gate valve is well suited for high-volume production flowlines, surface facility piping, injection systems, heater-treaters, and moderate-pressure upstream operations. The 4-1/16" bore allows increased flow capacity while maintaining secure isolation.
The DD trim option is suitable for standard, non-sour service involving hydrocarbons, brine, produced water, and general oilfield fluids. Manual handwheel operation provides controlled actuation in field environments without the need for hydraulic or electric systems. Rugged construction and a service-friendly design support consistent performance across frequent operating cycles.
