Screwed CS Ball Valves

Q: How do I operate a Screwed CS Ball Valve with a mild steel handle?

A: To operate this valve, simply turn the handle a quarter turn. The PVC sleeve ensures a secure, comfortable grip and insulation, making manual operation straightforward and safe.

Q: What is the benefit of the PTFE (Tef lon) seat material in these valves?

A: PTFE seats provide excellent chemical and thermal resistance, ensuring reduced friction, tight shut-off, and longevity even in aggressive or high-temperature environments.

Q: When should I choose this type of ball valve?

A: Opt for this ball valve when you need failure-resistant, fire-safe, and corrosion-resistant shut-off solutions in applications involving water, oil, gas, or steam-particularly within -20C to 200C and up to 80 Bar.

Q: Where can these screwed ball valves be installed?

A: They are suitable for installation in industrial plants, petrochemical sites, plumbing systems, and water supply networks, anywhere BSP or NPT threaded connections are used.

Q: What process is used to test the valve's safety and performance?

A: Each valve undergoes hydrostatic testing at 1.5 times its working pressure to ensure reliability and meet international standards like ASTM A105, API 607, and BS 5351.

Q: How does the fire-safe body design enhance safety?

A: The fire-safe design ensures that, in case of external fire, the valve maintains its integrity and prevents internal leakage, safeguarding critical installations against hazardous media leaks.
