JOUCOMATIC 54490022 – ISO 4 5/3-Way Pressure Held Solenoid Valve

JOUCOMATIC 54490022 – ISO 4 5/3-Way Pressure Held Solenoid Valve

The JOUCOMATIC 54490022 is a high-performance 5/3-way solenoid air-operated pneumatic valve from the Series 544. This large, robust valve is designed for versatile and precise control of compressed air or neutral gases in demanding industrial applications. The valve’s key feature is its pressure-held center position, which allows a connected cylinder’s piston to be stopped and held in any intermediate position. Conforming to the ISO 5599/1 size 4 standard, this valve has a high flow rate of up to 7000 L/min, making it an ideal solution for controlling large pneumatic actuators.

Key Features

• 5/3-Way Function: The valve has five ports and three positions, with a unique pressure-held center position.
• Pressure-Held Center: In the neutral position, a cylinder’s piston is held in place by trapped air, providing a rigid mid-stroke stop.
• Double Solenoid Actuation: The valve is actuated by two solenoid pilot signals and returns to the center position via springs.
• ISO 4 Size: Conforms to the ISO 5599/1 standard for size, with a very high flow rate of up to 7000 L/min.
• Wide Pressure Range: It can operate with a pilot supply pressure from 3 to 12 bar.

About this Valve Function

The diagram on the label identifies it as a 5/3-way valve with a pressure-held center. This means it has five ports and three positions. The center position is a “pressure held” or “closed center” position (W1), where the working ports (2 and 4) are blocked and isolated from the pressure and exhaust ports. This allows a pneumatic cylinder, for example, to be stopped and held in an intermediate position.

The valve is solenoid air-operated with pilot signals. A signal to port 14 shifts the spool to one position, and a signal to port 12 shifts it to the other. The valve stays in the center position when there is no pilot signal.
