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.
Moduflex dual valve combines two, 4-way valves into one valve body, it features two independently operated valves in the Size 1 valve body. :)
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.
The idle air control valve is located on the throttle body, and the EGR valve is located on the intake manifold.
A 4-way protection valve in an air brake system helps manage air flow and pressure to ensure safe and effective braking. It typically includes functions for supply, exhaust, and pressure protection, allowing for effective control of the brake system. In the event of a malfunction or pressure drop, the valve can isolate certain components to maintain overall system integrity and prevent brake failure. This enhances safety by ensuring that the braking system remains operational even in the presence of leaks or other issues.
Remove the vacuum hose from the EGR valve. Pull the valve out of the air cleaner housing. Reverse the process to install the new valve.
On my 1997 Protege a hose runs from the valve cover to the air intake assembly. Where the hose connects to the valve cover is the PCV valve.
The recommended installation height for an air admittance valve is typically between 4 to 6 inches above the highest point of the fixture it serves.
Should be on the air compressor for the suspension. Under the hood on the drivers side just behind the battery is the compressor. The black cylinder with 4 air lines coming from it (these may be covered by black split-loom) is the air dryer. Look under that for the valve. It looks like a tire valve. Remember: the air bag solenoids must be open for this fill technique to work. (Key - on, Air suspension - on) If the Check Suspension light is on, the system is off.
clean or replace your idle air control valve.
The Air Bypass valve location is shown on the vacuum schematic decal on the bottom front of the hood. Take off the 2 or 4 bolts holding the plastic engine cover and pop off the cover. You'll then see your vacuum hoses leading to the valve. There are 2 or 3 - 1/4 inch hoses leading to the base of the valve and one or two 3/4 inch hoses attached to the valve itself
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.
