BALL VALVES
ProMetal provides ball valves in all common materials from forged LF2 up till high alloy super duplex, and always referring to a wide range of standards within EN/DIN and ANSI/API.
The valves are used for different applications, mainly for oil and gas industries.
Depending on which application the valve should be used in, it can have different attributes/qualities for different situations. This could be regarding to how high the pressure in the system is, the resistance to hot and cold temperatures, connections, strength of the thread and corrosion resistance.
The closing function in the ball valve is conducted by either a floating ball or a trunnion mounted ball, depending on which position the valve is mounted in. Ball valves are very suitable to e.g. pumping of waste water or other mediums with larger amount of dirt.
The valves are supplied both to the sub sea and to the topsite applications delivered in pressure class up to 4500 ANSI and API 10,000 designed for API6A and 6 d.
