Working Principle

The Sanitary Butterfly Valves are triple offset structure and suitable for high temperature, high pressure, corrosion, etc. Its are quarter-turn valves which are used for isolating or regulating flow. They are favored for being lighter in weight, requiring less support and are suitable for water and gas, which makes them useful across industrial, mining and power applications.

Advantage

The Sanitary Butterfly Valve has various advantages such as good sealing performance, convenient operation, and quick opening and closing. They have no flanges, making the pipes more elegant and easy to bind together. These valves feature a triple offset elasticity or multi-layer hard sealing configuration, and the hard-sealed configuration for reliable sealing performance. The sealing of the disc can be replaced by loosening the coil bolts, saving the cost of the valve. In addition, there are annular bosses at the inlet and outlet of the valve, which is beneficial to the heat absorption and diffusion of the valve and pipe welding.

Application

Pharmaceutical, Food, Beverage, Cosmetic, and Fine chemical process Industries.

Actuator Control mode

According to the site condition has the following three kinds of control mode, the reasonable selection of the control method can make your valves service life more longer, more convenient operation, cost savings.

1.Normally open type user:

Suitable for pneumatic valve in the working time longer occasion. When the valve is normally open spring does not load external gas source thrust, then the valve fatigue to a minimum. Because it is by the air pressure to close valve, so need filed air pressure stability, air supply reliable.

2.Normally closed type user:

Suitable for pneumatic valve is in the closed time working longer occasion. For depends on the spring to close, when air pressure to drive the piston push spring, valve open. So for the normally closed user this valve service life more long, gas more economical. At the same time when the air supply fails, the valve is in the closed state, this control state is the most widely used.

3.Double acting type user:

Double acting type refers to the two chambers can be input compressed air separately, realize the two-way movement of the cylinder, no spring in the cylinder, the valve opening and closing rapidly, and can be used for large stroke valve, because it is by air pressure to close valve, so need the field gas source stability, air supply reliable.
