Class 600 Two-Piece Ball Valve

Class 600 Two-Piece Ball Valve

A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you "see" the valve's position. The ball valve, along with the butterfly valve and plug valve, are part of the family of quarter turn valves.

Two piece ball valves are full port, silicone free valves that come standard with lever locking device. A full port or more commonly known full bore ball valve has an over-sized ball so that the hole in the ball is the same size as the pipeline resulting in lower friction loss. Flow is unrestricted but the valve is larger and more expensive so this is only used where free flow is required, for example in pipelines which require pigging. A full range of economical ball valves intended for common fluid control applications. Available in standard and full port threaded, full port solder end, and full port threaded end direct mount. The special drilling of the valve automatically bleeds the interior of the valve once the valve is closed.

So Class 600 Two-Piece Ball Valve is a kind of two piece ball valve that is fully rated to class 600. There are some important information as follows: Type of Connection, R F and RTJ flange ends to ANSI B16.5 or API 605 and MSS SP-44 standard, BW flange ends to ANSI B16.25 standard, Lever, Connection dimensions of Worm Gear actuator, Electric actuator, Pneumatic actuator to ISO 5211 standard, Anti-static Electricity constructions "AS" and Fire-safe constructions "FD".
