Quick exhaust valve works

As shown in Figure 1, the valve has three ports: P, A, and T. Port P is connected to the air source, port A is linked to the actuator, and port T is vented to the atmosphere. When compressed air is supplied to port P, it pushes the spool to the right, allowing air to flow from P to A, which then powers the actuator. Conversely, when there is no compressed air at port P, the air inside the actuator flows back through port A, causing the spool to move to the left. This action closes the path between P and A while opening the connection between A and T, enabling the rapid exhaust of air through T. A quick exhaust valve is typically installed between the directional control valve and the cylinder. This setup allows the cylinder to release air quickly without having to pass through the main valve, significantly increasing the speed of the cylinder's movement. As a result, the overall work cycle is shortened, improving the efficiency of the pneumatic system. This feature is especially useful in applications where fast response times are required, such as in automated machinery or high-speed production lines.

Air Cooled Water Chiller

The air-cooled screw low-temperature chiller, with shell-and-tube evaporator and condenser, and fin heat exchangers, works well for R22, R404A, R410A, R134A, R407C, R513A, and other refrigerants. Most applications are for freezing processes in medicine, chemical industry, electronics, food processing, etc. The unit has a cooling capacity range 60kw~340kw with an outlet temperature 5C~-35C.

For an integrate system, our air cooled chiller can also come with water pump, water tank, for a modularized package.
