How to choose this product
butterfly-valve

Butterfly valves are used to shut off or, less frequently, control the rate of flow of a liquid. They have either flexible or metal seals. Small-diameter models can be operated by hand, while larger versions require the use of gearing or servomotors.

Technologies

These devices can be either lug- or wafer-type. The former are installed using tapped lugs, while the latter use four locating lugs.

Advantages

- Low maintenance
- Light and compact
- Low pressure loss
- Simple, rapid operation

Disadvantages

- Interrupts flow even when open
- Unsuitable for high differential pressures
