Working Principle

The Non-Sanitary Ball Valve uses a hollow, perforated and pivoting ball to control flow through it. The Non-Sanitary ball valve drives the valve handle to rotate by a transmission, which in turn drives the ball to rotate about an axis perpendicular to the flow. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle.

Advantage

1 The structure is simple, the weight and volume are relatively small, and it is easy to disassemble and repair.
2 Since the valve stem only rotates, the packing seal of the valve stem is not easily broken, and the sealing capacity increases as the medium pressure increases.
3 The fluid resistance is small, and the full-bore ball valve has substantially no flow resistance. Pneumatic ball valves are one of the least fluid resistances in all valve classifications.
4 The operation is simple and rapid, and it only needs to be rotated by 90° from full opening to full closing, which is convenient for long-distance control.
5 It is suitable for a wide range of applications, from a few millimeters to a few meters, from high vacuum to high pressure.

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.
