Applications of Worm Gear Wafer Butterfly Valve

Wafer type concentric butterfly valve with worm gear are made with cushy seal fabrics, so they are able to most effective be used for elementary (water and wastewater remedy vegetation), distinctiveness fluids (chemical compounds, abrasive fluids, and so forth.), and gases as much as 200 psi and 400° F.

● Water treatment.

● Water distribution.

● Water transmission.

● Aeration system.

● Fire protection, etc.

Butterfly Valve Wafer Type with Worm Gear Features

Wafer type concentric butterfly valve with worm gear is composed of a stem that travels alongside the middle line of the disc within the heart of the pipe bore, with the seat positioned within the internal diameter of the valve frame. This non-offset valve configuration is often referred to as a resilient seat valve as it is determined by the versatility of the seat rubber when final the go with the flow to verify a competent seal. In this kind of valve, the valve plate first interacts with the seat at roughly 85° and rotates 90°. This type of butterfly valves are extensively utilized in low-pressure programs.

Advantages of Butterfly Valve Wafer Type with Worm Gear

One of the best things about wafer type concentric butterfly valves is that it uses a neutral seal structure.

The lower and upper end of the disc close to the valve stem are two very smooth flat surfaces situated close to the rubber seat ring. This prevents the medium from leaking.

While the valves are closed, the disc gradually compresses while rotating. This causes the seat ring to deform elastically.
