Gate Valves By Design

SQK API 600 Gate Valvecovers bolted bonnet steel gate valves for the petroleum and natural gas industries,

SQK API 602 Gate Valve is a compact but extremely sturdy design for high-pressure-temperature service.

SQK ASME B16.34 Gate Valve is essential to those who deal with flanged, threaded, and welded-end valves. The standard covers pressure-temperature ratings, materials, marking, and other characteristics of cast, forged, and fabricated valves

SQK API 603 Gate Valve specifies the requirements for a heavy-duty series of bolted bonnet steel gate valves for petroleum refineries and related applications where corrosion, erosion, and other service conditions would indicate a need for full port openings, heavy wall sections, and large stem diameters.
