What are the three control methods for pneumatic angle seat valves?

Compared with solenoid valves and other valves, pneumatic angle seat valves are economical, safe to use, maintenance free, and long lasting. At the same time, some advanced pneumatic angle seat valves also have the advantages of a unique fixed piston seal, advanced pneumatic actuators, and a large flow valve body. It is widely used in food and chemical processes, sterilization machines, autoclaves, dry cleaning machines, dryers, beer production lines, etc.

Pneumatic angle seat valve features:

1. Stable performance, easy to install and maintenance-free, long working life

2. Work sensitive and reliable, automatic valve stem correction

3. Anti-corrosion, large flow, small flow resistance, high cost performance

Installation and maintenance of pneumatic angle seat valves must comply with applicable safety regulations:

1. The pipeline must be clean and free of pollution.

2, installed according to needs, but Zui so that the executive body is facing up. Pay attention to the flow direction.

3. Connect the valve and pay attention to the alignment of the pipe. Only remove the actuator when the user requests it.

4. Shut off the fluid and control the air supply and reduce the pressure in the piping system before opening or repairing the angle valve.

The pneumatic angle seat valve has three control modes according to the working conditions of the site. Reasonable selection of the control mode can make your valve have a longer service life, convenient operation and cost saving.

1. Normally open users:

Applicable to the occasion that the working time of the pneumatic valve is long, the spring is not loaded and the air source is thrust when the valve is normally open. At this time, the fatigue of the valve drops to low, because the valve is closed by air pressure, so the air pressure at the site needs to be stable and the air supply is required. reliable.

2. Normally closed users:

Applicable to the occasion that the working time of the pneumatic angle seat valve is long when the closing time is long. Because the spring is closed, when the pressure of the air source pushes the piston to open the spring, the valve will open, so for the normally closed type user, the valve has a longer service life. The gas consumption is more economical, and when the gas source fails, the valve is in a closed state, and the zui used for this control state is extensive.

3. Double-acting users:

Double-acting type refers to cylinders with two chambers that can input compressed air separately to realize two-way movement. There is no spring in the cylinder. The valve opens and closes quickly. It can be used for large stroke valves. Because it is closed by gas source pressure, it needs on-site air supply. Sufficient and stable, reliable gas supply.

Pneumatic angle seat valves are generally used for short-time frequency start-ups. They are characterized by sound sensitivity and the characteristics of the measures. The common solenoid valve can be used to control the flow of gas and liquid by pneumatic control. It can realize the requirements of temperature control and dropping liquid.
