Guardian 2″ 316ss 2000PSI 2 PC Full Port Ball Valve
This valve shares the same robust stainless steel construction and 2000 PSI CWP rating, optimized for higher-flow systems. The 2-piece body design facilitates service without removing the valve from the line. The lockable handle and blowout-proof stem provide added safety and longevity in plumbing or industrial setups.
DAN SPEED 2″ NPT Female 316 Stainless Steel Full Port Ball Valve
Features include a full port body and ball design for maximum flow, low operation torque, and 316 stainless steel construction. The valve is serviceable and can be disassembled via threaded connections, with female NPT ports for straightforward installation in gas, oil, or water lines. PTFE seals contribute to corrosion resistance and longevity in challenging environments.
DAN SPEED 2″ NPT 316 SS Full Port Ball Valve (2 pcs)
This model combines a full port design with 316 stainless steel components and a low operation torque. It is serviceable through threaded connections, with female NPT ports. The valve uses PTFE seals to maximize corrosion resistance and lifespan, making it suitable for water, oil, and gas services where durability is essential.
DAN SPEED 2 Inch Male x Female NPT Ball Valve S304 Stainless Steel
Made from S304 stainless steel, this 2-inch valve supports a broad temperature range (-60 F to 450 F) and full port flow. The male-to-female NPT configuration offers flexible installation in existing piping. It is designed for water, oil, and gas applications where high strength and reliable sealing are required in a compact form factor.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Stainless steel (316/304) offers superior corrosion resistance in water and chemical environments, while brass components may be adequate for basic water systems.
- Port size and flow: Full-port valves minimize pressure drop and maximize flow, which is important for high-demand systems.
- Pressure ratings: For 2000 PSI CWP applications, verify the valve design and sealing method to ensure compatibility with the intended service.
- Connection type: NPT threaded connections are common, but consider socket or flanged options if your piping requires an alternate interface.
- Maintenance and serviceability: Serviceable valves enable disassembly and resealing, extending valve life in challenging environments.
- Handle and safety features: Lockable handles and blowout-proof stems improve safety in high-pressure installations.
- Temperature range: Ensure the valve materials and seals withstand the service temperature, especially for oil/gas or hot water lines.
- Warranty and support: Check manufacturer documentation for warranty terms and typical service life under your operating conditions.
