What is flange butterfly valve?
A flange butterfly valve is a type of quarter-turn flow control device. It has two components: a disc attached to the stem and a body containing flow ports, which are sealed with an elastomeric liner. In operation, the disc is turned 90 degrees within the body using an external actuator such as a handle or motor. When closed (90 degree angle), this valve completely blocks off the flow of fluid through it, while when opened (0 degree angle) it allows full unrestricted access to flowing liquid or gas.
What is double flange butterfly valve?
A double flange butterfly valve is a type of flow control device commonly used in the process, water treatment, power and energy, as well as other industries. These valves are known for their ability to provide tight shut-off at high pressure with minimal leakage; they are also an economical choice due to their low cost and simple design.
Double flange butterfly valves work by having a flat circular plate mounted on an axis inside a pipe or duct. This plate, referred to as the disc or vane, has edges that fit snugly against two opposing flanges that form the body of the valve. As this disk rotates within its seat, it opens and closes off fluid flow. This is accomplished by using an external actuator such as a gearbox, electric motor or lever system depending on application requirements.
What is a single flange butterfly valve?
A single flange butterfly valve is a type of quarter-turn rotary control valve specifically designed for medium and high flow applications. It incorporates a disc that rotates within the body to open, close or modulate the fluid flow. A single flange butterfly valve consists of an outer housing with two or three concentric sections joined by bolts to form the flange on one end. The other end typically contains a central shaft connected to a gearbox, lever, actuator, or electric motor for easy operation from outside the line.
wafer vs flanged butterfly valve
The choice between a wafer and flanged butterfly valve depends on the application. Wafer-style valves are designed with two lugs, which help it fit into standard pipeline grooves, enabling easy installation without additional hardware. This makes them ideal for small or low-pressure applications such as water systems or irrigation lines. They have shorter face-to-face distances than flange type valves, so they take up less space in the pipeline system. That being said, because there is no direct connection between the valve and surrounding piping components, wafer type valves are prone to leaking when under high pressure conditions due to their lack of support from attached components.
Flanged butterfly valves feature bolts that attach directly to surrounding pipe connections, providing stronger support for higher pressure applications like steam systems or cooling networks within manufacturing facilities. The presence of a thicker body shape also provides superior performance for these heavy duty applications compared to the thinner body shapes used with wafer types. However, this thicker shape also requires greater clearance around it as well as more complex installation procedures and additional mounting hardware which can make it more expensive and time consuming to install than its counterpart option.
