JOUCOMATIC 54391028 – ISO 3 5/3-Way Pressure Held Solenoid Valve
A JOUCOMATIC 54391028 is a 5/3-way pressure-held solenoid valve with an ISO 3 size and a flow rate of 4200 L/min.
JOUCOMATIC 54391028 – ISO 3 5/3-Way Pressure Held Solenoid Valve
The JOUCOMATIC 54391028 is a high-performance **5/3-way solenoid air-operated pneumatic valve** designed for versatile and precise control of compressed air or neutral gases. This valve is part of the **ASCO/Emerson** portfolio and conforms to the **ISO 5599/1 size 3** standard, ensuring interchangeability with other valves of the same standard. Its key feature is the **pressure-held center position**, where all ports are blocked, allowing a connected cylinder’s piston to be stopped and held in an intermediate position. With a high flow rate of **4200 L/min** and a maximum pressure of **12 bar**, it is an ideal solution for a variety of demanding automation applications.
Quick Navigation
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 3 Size: Conforms to the ISO 5599/1 standard for size, with a high flow rate of 4200 L/min.
- Wide Pressure Range: It can operate with a working pressure of 3 to 10 bar (internal pilot) or up to 12 bar (external pilot).
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 5 ports (1 pressure, 2 work, 2 exhaust) and 3 positions. The center position is a “pressure held” or “closed center” position, 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.
