NPT Threaded Gate Valve

NPT threaded gate valves have internal threads (such as NPT, BSPT, or similar) on both ends of the body. The pipe is threaded externally, so you can simply screw the valve onto the pipe. No welding or hot work is required. This makes installation and removal quick and easy.
Where They Are Used
Threaded gate valves are commonly found in oil transmission, natural gas lines, storage and transfer systems, refining equipment, and chemical service. They are also well suited for metallurgy, machinery, and power plant piping, especially in applications where frequent disassembly is expected.
Key Features
Multiple Material Strengths – Available in stainless steel (corrosion resistance), brass (excellent for water & mild chemicals), or forged steel (low/medium pressure). Our brass female thread gate valve and stainless steel options cover a wide range of media.
NPT & BSPT Threaded Ends – As a reliable NPT threaded gate valve, it features precision internal threads on both ends. Simply screw onto externally threaded pipe – no welding, no hot work. Installation and removal are quick and easy, even in tight spaces.
Oil & Gas Pipeline Ready – Designed for oil & gas pipeline threaded gate valves used in oil transmission, natural gas lines, storage/transfer systems, refining equipment, and chemical service. This NPT-threaded gate valve also excels in metallurgy, machinery, and power plant piping, where frequent disassembly is expected.
Reliable Shut‑Off with Seat Options – Forged steel body provides good strength for low to medium-pressure applications. Sealing structure delivers stable shut‑off (fully open/closed only – no throttling). Different seat materials are available to match specific media.
Flexible Sizes & Standards – Sizes DN15–DN200 (½" to 8"). End connections: threaded, socket weld, or flanged. Compliant with DIN, ANSI, JIS, BS, or GB.
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.
