Filling Valve

Sanitary Valves

Working Principle

The filling valve is a switching valve that can accurately and quantitatively control the flow. The special structure and sealing design at the bottom of the valve can ensure filling without dripping while ensuring flow. It has been widely used in filling machinery, especially for viscous, creamy and easy-froth fluid filling.

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.
