A ball valve according to the invention has a disc (8) with a shaped opening (4) adjacent to the ball (3) such that the flow characteristics through the ball valve may be modified.
A ball valve comprises a ball rotatably disposed within a housing, and a trunnion plate supporting the ball.
A composite wellbore ball valve has a spherical, fiber reinforced composite ball valve closure.
If the ball valve operates electrically, it is driven by a motor, the so-called actuator.
In other industries, an electrically operated ball valve is used to control the supply of lubricants.
A cartridge assembly for converting a single-handle faucet from a ball-type valve to a cooperating plate valve.
If you need a shutoff around the location of a regulator, it would be safest to install a ball valve upstream.
Features: A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball (called a “floating ball”) to control flow through it.
Ball valve having retention of a seat insert (64, 118) within a seat ring (46).
Installing a Forged Steel Ball Valve allows water to be turned off to a section of a plumbing system without having to turn off the main water supply.
Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open.
The ball valve and the actuator have particularly interesting uses in oil related industry and on oil rigs or the like.
Unlike a ball valve or gate valve, this disk is always present within the flow and therefore will cause pressure drop.
Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.
Unlike a ball valve, the disc is always present within the flow, so a drop is always induced in the flow, regardless of valve position.
Unlike a ball valve, the disc is always present within the flow; therefore a pressure drop is always induced in the flow, regardless of valve position.
8, easy maintenance: the ball valve is simple in structure, the sealing ring is generally active, the removal and replacement are more convenient.
In principle, it is able to serve and closing device for closing the radiator if necessary removing it (instead of a ball valve).
A ball valve (68) type fluid coupling (10) having identical interconnectable parts (12, 14) characterized by low fluid spillage during disconnection.
The trunnion pipeline ball valve can be designed with the double sealing structure before and after the ball for some special service conditions and user requirements.
