Where 3V and 4V Series Directional Valves Are Used

3V and 4V series directional valves appear in many automation machines because they cover two very common pneumatic jobs: single-output air control and double-acting cylinder direction control. The 3V110, 3V210, 3V310 and 3V410 models are useful for simple supply-and-exhaust circuits. The 4V110, 4V210, 4V310 and 4V410 models are useful when a double-acting cylinder must extend and retract under air control. For buyers comparing products inside the solenoid valve category, industry application is a practical way to narrow the choice. The same valve family can be used in packaging, assembly, textile machinery, woodworking, light handling and general factory automation, but the correct size depends on actuator load, cylinder bore, cycle speed and available installation space. Packaging Machinery Packaging machines often use pneumatic cylinders for pushing cartons, guiding film, cutting, sealing, clamping and rejecting products. Small functions may use 3V valves when a spring-return cylinder or air blow point is enough. For example, a small reject nozzle or single-acting stopper can use a 3/2 way valve to supply air and exhaust quickly. Double-acting cylinders on packaging equipment often use 4V valves. A…

How to Select 3V110 to 4V410 Pneumatic Solenoid Valves

Choosing between 3V110, 3V210, 3V310, 3V410, 4V110, 4V210, 4V310 and 4V410 is not only a matter of thread size. These pneumatic solenoid valves differ in circuit function, flow capacity, actuator matching and installation space. A good selection starts from the movement the machine needs, then works backward to valve function and size. All of these models are part of the solenoid valve range, but they should not be treated as one interchangeable group. The 3V models are 3/2 way valves for single-output air control. The 4V models are 5/2 way valves for double-acting cylinder direction control. Step 1: Identify the Pneumatic Circuit Start by checking the actuator. If the equipment uses a single-acting cylinder with spring return, or if the valve only needs to turn air on and exhaust it after the signal stops, the 3V series is normally the correct direction. The circuit needs supply, output and exhaust. If the actuator is a double-acting cylinder, the machine needs air alternately supplied to both sides of the piston. In that case, choose the 4V series. A 5/2 valve such as…

3V vs 4V Directional Control Valves: Main Differences

For many pneumatic machines, the model number on a valve looks simple, but the function behind it decides how the actuator moves. The 3V110, 3V210, 3V310 and 3V410 valves are normally used as 3/2 way air solenoid valves, while 4V110, 4V210, 4V310 and 4V410 valves are normally used as 5/2 way directional control valves. Both groups belong in the solenoid valve category, but they solve different circuit problems. The practical difference is the actuator type. A 3V valve is usually selected for a single-acting cylinder, air blow control, signal air, or a small pneumatic device that needs supply and exhaust through one working port. A 4V valve is usually selected for a double-acting cylinder that needs two cylinder ports to switch between extension and retraction. Port Function Is the First Difference A 3V series valve has three ports and two positions. One port receives supply air, one port connects to the actuator or output line, and one port exhausts air when the valve switches back. This layout makes the valve suitable for single-acting cylinders because the spring inside the cylinder…
