Product Description


Industrial DN600 Pn10 Pn25 NBR Seat Butterfly Valve Double Flanged Quick Open with Lever/Gear/Bare Shaft/Electric/Worm Gear
Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow. However, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties.

A butterfly valve is a quarter turn rotational motion device that utilizes a rotary disc to allow, obstruct, or control the flow of fluids in a piping system. It features a rotating disc that is situated on the passageway of the flowing media. The disc is rotated and controlled by an external actuating mechanism through the stem attached to it. When the disc is coplanar to the flow cross-sectional area, the flow is fully obstructed. Otherwise, the fluid is fully or partially allowed to pass through the butterfly valve. It takes a 90° turn to fully open a butterfly valve from a closed position, which means the disc should lie perpendicular to the flow cross-sectional area.

Butterfly valves are quarter-turn valves like ball valves and plug valves. They have a fairly simple construction and operation mechanism, and they have a compact size designed to fit two pipe flanges. They can be operated manually or by an automatic actuating mechanism that is integrated into the process control system of the pipeline. They are ideal for on-and-off applications, but their applications to flow throttling are limited.

There are several types and designs of butterfly valves available, rated in varying temperatures, pressures, and flow rates to suit the needs of pipeline systems handling liquids and gases.

Butterfly valves are quarter-turn valves that are best used for the stop/start of media flow in pipelines. When the valve handle is turned 90°, it either opens or closes completely. Throttling can be a bit tough, but these valves can still be used for regulating purposes.

A butterfly valve can be either operated manually, pneumatically, or electrically through an actuator. Using the actuator can help in controlling the valve - the actuator will be connected to the disc and it will move the disc according to the required operation.

For each type of operation, there is a particular kind of tool that helps in the actuation. For example, pneumatically controlled butterfly valves have a piston attached to them. Technically speaking, this is the best method to control a butterfly valve as it enables quick shut-off and turn-on capacity.

The construction of a butterfly valve is relatively simple, with the rotation of the valve disc controlling the fluid flow. In the closed position, the disc blocks the valve bore while in the open position, the disc is oriented perpendicular to the flow direction to allow flow.

The main components of a butterfly valve are stem, body, actuator, sealing arrangement, bonnet, seat, disc, upper bearing, and lower bearing. It is a helpful device to isolate and regulate the flow of a liquid throughout the pipes. It is considered a quarter-turn device as it can open or close with just a quarter turn.
