In this article, butterfly valve manufacturers explain their working principles, the components that make up the butterfly valve and the different types available. If necessary, you can browse and choose our Butterfly Valve fire protection Grooved type.
Butterfly valves can be used for lightweight and low-cost control of water flow in fire sprinklers and riser systems. The butterfly valve isolates or regulates the fluid flowing through the piping system. Although they can be used with liquids, gases and even semi-solids, they are used for Butterfly Valve fire protection. Grooved type is used as a control valve to open or close the water flow to the pipes of the fire sprinkler or riser system. In this article, butterfly valve manufacturers explain their working principles, the components that make up the butterfly valve and the different types available.

How the butterfly valve works:
Used for Butterfly Valve fire protection. Grooved type starts, stops or throttles water flow through the rotation of the internal valve flap. When the disc rotates parallel to the water flow, the water can pass freely. Rotate the disc 90 degrees, and the movement of water into the system pipe stops. The thin disk can always remain in the waterway without significantly slowing down the movement of water through the valve.
The rotation of the disc is controlled by the hand wheel. The handwheel rotates a rod or lever to turn the valve flap, and at the same time rotates the position indicator (usually a bright piece extending out of the valve) to show the operator the direction the valve flap is facing. This indicator can confirm at a glance whether the valve is open or closed.
The position indicator plays an important role in maintaining the normal operation of the fire fighting system. The Butterfly Valve fire protection Grooved type is used as a control valve to cut off the water flow to the entire part of the fire sprinkler or standpipe system. When the control valve is inadvertently closed, the entire building cannot be defended. Position indicators help fire professionals and facility managers find closed valves and quickly reopen them.
Most Butterfly Valve fire protection Grooved types also include an electronic tamper switch that communicates with the control panel and sends an alarm when the valve flap rotates. Usually, they include two tamper switches: one for connecting to the fire control panel, and the other for connecting auxiliary equipment, such as a bell or horn.
