Socket Weld Gate Valve

Socket weld gate valves feature recessed sockets machined into both ends of the valve body. You insert the pipe into the socket and then weld around the joint.  These valves are ideal for applications where leakage is not acceptable—such as high pressure, high temperature, or hazardous media. 
Specific Applications
Socket weld gate valves are commonly used in oil transmission, natural gas lines, storage and transfer systems, refining equipment, and chemical plants. They are also well suited for metallurgy, machinery, and power piping, especially in critical service or imported equipment projects.
Key Features
Superior Material Options – Available in stainless steel (excellent for corrosive/hazardous media), carbon steel, or brass/bronze. Our refinery-grade Socket Weld Gate Valve is built for high-pressure, high-temperature, and critical service applications.
Permanent, Leak‑Tight Joints – SW (socket weld) ends with recessed sockets. As a true Socket Weld Gate Valve, it allows you to insert the pipe and weld – creating a strong, reliable connection that eliminates leakage, ideal for oil/gas pipelines, refining equipment, and chemical plants.
Designed for Critical Service – The forged steel body withstands extreme conditions. Perfect for applications where leakage is not acceptable, including refinery systems, power piping, and imported equipment projects.
Reliable Shut‑Off & Seat Options – Stable sealing under routine service. Choose PTFE, metal, or other seat materials to match specific media.
Standards & Sizes – Available with socket weld, threaded, or flanged ends.
Quality Certification
We hold ISO 9001, ISO 14001, and ISO 45001 certifications, plus a special equipment production license (TS). Our products are made to API, ANSI, JIS, ISO, BS, JB, and GB standards. This covers material checks, non‑destructive testing, precise measurements, and valve strength/sealing performance.
Custom Manufacturing Services
You send us a drawing or sample, and we review the requirements. Then we confirm the drawing and give you a quote — faster if you provide a 3D model. After order confirmation, we schedule batch production.
