Screwed Valve Manufacturer

A Screwed Valve (also known as Threaded Valve) is a type of industrial valve that uses threaded end connections (typically BSP, NPT, or BSPT) for installation. These valves are primarily used for low to medium pressure piping systems where easy and secure connections are required.

Made from materials like brass, stainless steel, forgedsteel, or cast iron, screwed valves are commonly found in oil & gas, water treatment, HVAC, steam, chemical processing, and general plumbing systems. Their compact design, ease of installation, and leak-proof threaded joints make them a practical choice for many industries, especially where welding is not feasible or desirable.

Top 10 FAQs about Screwed Valves

1. What is a screwed valve used for?
• Used to control or isolate flow in low to medium pressure systems via threaded pipe connections.
2. What are the common thread standards?
• BSP (British Standard Pipe), NPT (National Pipe Thread), BSPT (Tapered British Thread).
3. What pressure rating do screwed valves support?
• Typically up to 800 PSI (Class 800) or more, depending on material and design.
4. Are screwed valves suitable for high-temperature applications?
• Yes, especially forged steel types—commonly used for steam, oil, and gas.
5. What sizes are available?
• Generally from ¼ inch to 2 inches; larger sizes may use flanged or welded connections.
6. Are they suitable for potable water?
• Yes, especially brass or stainless steel valves with food-grade seals.
7. Can they be reused after disassembly?
• Yes, if threads and sealing integrity are maintained.
8. What’s the difference between NPT and BSP threads?
• NPT is a U.S. standard (tapered), BSP is a British standard (can be parallel or tapered); they are not interchangeable.
9. Do they require sealants?
• Yes, typically PTFE tape or thread sealant to ensure leak-proof connections.
10. Are there fire-safe or anti-static variants?

• Yes, fire-safe screwed ball valves and anti-static designs are available for hazardous services.
