CL300 10'' Trunnion Mounted Ball Valve

Ball valve

Product introduction

A ball valve is a valve with a ball as the closing part. The main function of the ball valve is to cut off and connect the fluid in the pipe. The ball valve uses the ball to rotate around the axis of the stem, realizing the purpose of opening and closing. The ball valve is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. It is mainly used for oil and gas storage and transportation, and it is used for controlling medium in chemical industry, metallurgy, papermaking, food industry, shipbuilding and other industries.  

Side mounted fixed ball valves are of two-piece or three-piece side mounted design, which conforms to API6D standard. The operating temperature is -46~200℃, especially suitable for pipeline fluid control with large diameter and high pressure. This series of valves are according to API 607 and API 6FA fire test.

Size range: 2 "~ 60 ((~ DN1500)"

Pressure grade: ASME CLASS 150~2500(PN16~PN420)

Main materials: carbon steel, stainless steel, alloy steel, duplex steel, nickel base alloy, etc.

Connection: flange end, butt welding end, HUB end, etc.

Operation mode: manual, pneumatic, electric and hydraulic, etc.

The characteristics

1. Low fluid resistance: full port ball valve has no resistance from the media.
2. Good sealing: the sealing surface is big so easy sealed, not only the soft seat made of flexible material as PTFE, or the metal seat that is manual polished to be totally zero leakage with the ball.       
3. Fast switching: PTFE and other flexible material has the merit of good self-lubricant; and to metal sealing, the bottom ring under ball adopts springs to make the sealing rings and ball to be closely sealed so the open will be very light if the outside pressure is bigger than the spring reload.      
4. Convenient maintenance, the seat is replaceable, easy to disassemble and change.
