Series 4 Valves and Solenoid Valves: Versatile Solutions for Demanding Applications

Series 4 Valves and Solenoid Valves are engineered to meet the versatile needs of modern pneumatic systems. Available in 3/2, 5/2, and 5/3-way configurations—including both closed center (CC) and open center (CO) functions—these valves are designed to handle a broad range of control applications.

With port sizes ranging from G1/8 to G1/2, Series 4 valves deliver air flows from 650 to 4000 Nl/min, making them ideal for everything from compact setups to high-demand industrial environments. The addition of new G3/8 port models with a flow rate of 1800 Nl/min further expands the range's flexibility.

Actuation options include:

• Electropneumatic actuation with mechanical spring return
• Electropneumatic actuation with external or internal air pressure return

These options allow for tailored control in various pneumatic circuits. All valves in this series include a manual override for stable operation, especially useful in harsh or arduous conditions.

Compatibility with solenoid Series U, G A8, and H8 ensures seamless integration into existing systems, while the ability of 3/2 NC valves to become NO by supplying air through port 3 adds functional adaptability.

Technical Highlights:

• Balanced spool design for precise operation
• Constructed with an aluminium body, stainless steel spool, and technopolymer end covers
• Fitted with NBR and PU seals for durability
• Installation possible in any orientation
• Operates within 0 to 60°C (or down to -20°C with dry air)
• For use with filtered air, lubricated or non-lubricated (ISOVG32 oil recommended for lubrication)

Series 4 stands out as a reliable choice for engineers looking for performance, durability, and control in demanding pneumatic applications.
