Working principle:

Pneumatic ball valves rely on pneumatic actuators to drive the rotation of the ball to achieve the opening and closing of the valve. When the control air source enters the cylinder of the pneumatic actuator, it pushes the piston to move. Through the transmission mechanism such as rack and pinion or fork, it drives the valve stem to rotate, causing the ball to rotate 90° inside the valve body, thus achieving the opening or closing of the valve.

Product performance and usage:

Pneumatic discharge valve uses compressed air to push the piston to perform linear reciprocating motion in the cylinder, thereby driving the valve stem to drive the valve disc to perform upward or downward movements, to achieve automatic opening and closing of the valve. In order to eliminate the phenomenon of residual media at the outlet of the container, it is often used as a bottom discharge and sampling function for reaction vessels, storage tanks, and other containers.

Selection of pneumatic discharge valve:

Pneumatic discharge valves are mainly used for bottom discharge of reaction vessels, storage tanks, and other containers. They are welded to the bottom of storage tanks and other containers through the flange at the bottom of the valve. Therefore, eliminating the phenomenon of residual process media at the outlet of the container is common. The pneumatic discharge valve should be correctly selected to expand upwards or downwards according to the actual working conditions. Like; For process media that are prone to crystallization or have dense concentrations, an upward expansion discharge valve is selected.

Working principle:

Using compressed air as a power source, the main control room manually or automatically triggers action commands to activate the intake and exhaust solenoid valves, supplying and discharging compressed air into the actuator. Compressed air acts on the piston or diaphragm, overcoming the frictional force of valve action and the spring force on the valve stem, driving the valve core to move up and down, and achieving the opening or closing of the valve.

Advantage:

Simple structure, easy manufacturing and maintenance; Small work schedule and short opening and closing time; Good sealing performance, low friction between sealing surfaces, and long service life; Low fluid resistance, suitable for fluids containing solid particles or high viscosity; The friction force of the sealing surface during the opening and closing process is smaller than that of the gate valve, and it is wear-resistant; Usually there is only one sealing surface, with good manufacturing process and easy maintenance.

Overview:

When the normally closed fluid solenoid valve is de-energized, it is in a closed state. When the coil is energized, an electromagnetic force is generated, causing the moving iron core to overcome the spring force and attract with the static iron core, thus opening the valve. When the coil is de-energized, the electromagnetic force disappears, and the moving iron core is reset under the action of the spring force, directly closing the valve. The normally open solenoid valve is the opposite. This type of valve features a simple structure and fast response speed, and is widely used in industries such as textile, printing, plastic and rubber, food machinery, and surface treatment.
