It depends on the application. A ball valve is better suited for smaller flow rates, anything requiring more than 2 ports, or for durability/sealing concerns. A gate valve is typically cheaper, better for higher flow rates, and requires a smaller installation space.
Read MoreThe stem is connected to a slot at the top of the ball which allows the ball to rotate a quarter turn (90 degrees). The shaft allows for a certain amount of lateral movement of the ball that is generated from the upstream pressure acting on the ball. This small lateral movement, in fact, produces ......
Read MoreSteam produced from water boilers is widely used in industrial applications. Industrial processes such as drying, mechanical work, electricity generation, and process heating are typical steam applications. Steam valves are used to reduce inlet steam pressure and to provide accurate regulation and c......
Read MoreParallel gate valves have a parallel faced gate like closing member. This closing member may consists of a single disc or twin discs with a spreading mechanism in between. The force that presses the disc against the seat is controlled by the fluid pressure acting on either a floating disc or a float......
