Moduflex dual valve combines two, 4-way valves into one valve body, it features two independently operated valves in the Size 1 valve body. :)

Pneumatic process control valves are used in process industries to control the flow of fluid by using pneumatic actuators. It requires 4.5 to 6 Kg/sq. cm of pressure to operate the valve. Control room sends electrical signals of 4-20 ma to field where I/P converter converts these electrical signals into pneumatic signals. Actuators use these signals to operate the valve. Actuators moves the stem up and down depending upon input signals and control the valve opening. 4ma- 0% opening 8ma- 25% opening 12ma- 50% opening 16ma- 75% opening 20ma- 100% opening
A technician can determine which port of a 4-way valve should be connected to which coil by referring to the valve's schematic or wiring diagram, which outlines the correct connections. Additionally, they can identify the ports by their designated functions, such as pressure, exhaust, and actuator ports, ensuring that the correct signals are sent to operate the coils appropriately. Testing the valve operation with a multimeter can also help confirm the proper connections.
Hydraulic and Pneumatic systems are similar in that they both use double/single acting cylinders to operate something - Be it an automatic door for pneumatics and other such trivial tasks, or JCBs with hydraulics. Another key similarity would be the way in which they work - they both take the easiest path where available and both use 3/2 valves. A major difference between them is the pressures involved, the output forces and the use of 4/3 (hydraulics) and 5/2 (pneumatics) to operate a double acting cylinder.
A pneumatic to current transducer is a device that converts pneumatic signals, typically in the form of air pressure, into electrical current signals, often in the range of 4 to 20 mA. This conversion enables the integration of pneumatic systems with electronic control systems, facilitating automation and monitoring. Such transducers are commonly used in industrial applications to ensure precise control of processes that involve air pressure. By providing a standardized electrical output, they allow for easier data transmission and analysis.
A 4-way air valve controls the direction of airflow in pneumatic systems by directing compressed air to different ports. It typically has four ports: two for supplying air to a cylinder and two for exhaust. When the valve is activated, it shifts between two positions, allowing air to enter one side of the cylinder while exhausting from the other, thus controlling the movement of the actuator. This versatile valve is essential in applications requiring precise control of actuator movement in both directions.
Plumb them in a series, the "out" from the 1st valve to the "in" of the second valve then the "out" from the second valve to return.

A four-way valve is used in hydraulic and pneumatic systems to control the direction of fluid flow. It typically has four ports and can direct the flow to two different actuators or change the movement of a single actuator by reversing its motion. This allows for versatile control in machinery, such as extending and retracting a cylinder, thus enabling efficient operation of various applications.

The number is four ways in and out of oil. Way valves in the hydraulic system with a number of ways in and out of the way oil and positioning are introduced. For example, two-position four-way valve.
This is not a forum for Valve technical assistance. I would check with their website forums for help.
r right r leaft frnt right front left. always start with the bleeder valve farthest away from master cylinder then work your way to the closest
The line coming from the Discharge Line, which comes from the Compressor into the 4-Way Valve
It could be the 4-way valve is stuck in heat, or cold. The 4-way valve is a reversing valve which reverses the direction that the refrigerant moves through the unit which would cause it to do exactly what you are talking about. I'm sorry, I just realized that you are talking about a car AC. The first answer is a good probability. Possibly a broken reed valve. Pardon my interruption! :o)
