Gas-over-Oil Actuated BW Ends Ball Valve

As a type of Ball valve, the Gas-over-oil actuated BW ends ball valve uses the Trunnion mounted as the sealing structure. The valve actuated by Gas-over-oil actuator, and uses carbon steel as body material. LYV®️ Gas-over-oil actuated BW ends ball valve can meet standards such as API, DIN. Produce size range from NPS2 inch up to 24 inch, DN50 to DN600. Pressure rating covers ANSI Class150LB and PN10, PN16, PN25. The Gas-over-oil actuated BW ends ball valve has many of applications, it widely used in fields such as Oil & Gas, Petrochemical, LNG, Power Generation, Water and wastewater Treatment, Coal Chemical, Pipeline Transport and more.

What is a ball valve?

Disc of the ball valve has a spherical shape, and a cylindrical channel (ported) is provided in the center to allow fluid to pass through. This spherical disc opens and closes by rotating it 90 degrees.

How does a ball valve work?

1)Disc (ball) is spherical and a soft seat is incorporated into the valve seat of the body, similar to a cock.

2)When the lever handle type is used, the fluid can be stopped or flown by turning the lever handle 90 degrees. Note that the larger the size, the larger the force is required to open and close, so the gear handle can be operated.

3)Excellent airtightness is obtained from the mechanical and physical properties of soft seat materials. However, there are restrictions on the use of high-temperature areas. Suitable for “on/off operation” using open or closed operation with common soft seat. It is not suitable for use at intermediate positions, depending on the construction or material of valve.

What is a V port ball valve?

Disc has an edge-shaped lambda character and uses a metal seat to control the flow rate at the intermediate opening and valve structure that allows closure while cutting contaminants in the fluid. It is suitable for controlling special fluids such as paper pulp, slurry, and viscous fluids.

What is the difference between full port and V-port?

V-port shaped edge cuts out any inclusion. Cutting fibers and solids depends on sliding between disc (metal) and seat (metal). If fibers such as pulp are contained in the fluid, ball valves, for example, will become clogged when closing, which will cause maintenance-related problems. However, in the case of lambda port valves, the metal edges are closed while cutting contaminants so that they are not blocked. The body has a flange structure and does not require special tools for
