Their construction complies with international standards, ensuring performance and safety in various harsh industrial environments.
Versatile ApplicationsDesigned for a wide operational spectrum, these valves accommodate media including water, oil, gas, and steam. Their temperature tolerance from -20C to 200C and wide pressure range makes them ideal for industrial, petrochemical, plumbing, and water supply sectors.
User-Friendly OperationThe quarter-turn mechanism, combined with a PVC-sleeved mild steel handle, facilitates smooth and ergonomic manual operation. The full bore structure ensures minimal flow restriction, promoting efficiency in demanding installations.
FAQ's of 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 (Teflon) 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.
