Product Detail

The API 600 Gate Valve is the industry standard for high-pressure, high-temperature isolation in oil, gas, and chemical piping systems. Constructed with a Bolted Bonnet (BB) and Outside Screw & Yoke (OS&Y) rising stem design, it provides exceptional structural rigidity and reliable shut-off performance. To ensure a "Plug-and-Play" installation, we provide a complete piping assembly kit including matching Companion Flanges (Counter Flanges), high-tensile Stud Bolts (ASTM A193 B7/B8) with Heavy Hex Nuts (A194 2H/8), and professional-grade Spiral Wound Gaskets (SWG). This holistic supply approach ensures dimensional compatibility, eliminates procurement mismatches, and guarantees leak-free integrity during field commissioning.

Design Description

API 600 Gate Valve: Designed to API 600 and ASME B16.34 standards, featuring an OS&Y (Outside Screw & Yoke) rising stem, bolted bonnet, and flexible wedge. It delivers optimal flow isolation with minimal pressure drop and exceptional thermal compensation.
Companion Flanges (Counter Flanges): Precision-machined to ASME B16.5 / B16.47 specifications, made from matching materials (e.g., ASTM A105N for carbon steel or A182 F316 for stainless steel) to ensure seamless welding and piping alignment.
Stud Bolts & Heavy Hex Nuts: Manufactured to ASTM A193 Grade B7 (with A194 Gr. 2H nuts) for high-strength carbon steel service, or ASTM A193 B8/B8M for corrosive environments, guaranteeing secure, high-tension flange joints.
Spiral Wound Gaskets (SWG): Engineered with a 316L stainless steel winding strip and flexible graphite or PTFE filler, offering superior resilience and seal integrity under high-pressure and high-temperature cycling.
