VP344R-5DZ1-A: Dual-Control Hub, Precise Direction Switching! High-Performance 5/2 Solenoid Valve Empowers Complex Pneumatic Logic​

In automated pneumatic systems requiring high reliability, stable two-position control, and complex logic interaction, a directional control valve capable of rapid response and precise holding is essential. The VP344R-5DZ1-A dual-solenoid, pilot-operated 5/2-way solenoid valve utilizes a dual-coil, pilot-operated design to achieve accurate spool switching and power-off position retention, making it the ideal control core for multi-actuator, high-cycle equipment.​​Core Product Advantages​​

• ​​Dual-Solenoid Memory Function​​Employs dual-pilot solenoid control (5DZ indicates dual solenoid). A pulse signal to either coil shifts the spool, which then remains in that position even after power is removed (memory function). This prevents unintended actuator movement during unexpected power loss, enhancing system safety.
• ​​Pilot-Operated for High Flow, Low Power​​The pilot-operated design uses low-power solenoid force to control the high-flow main air path. It offers fast response times, low power consumption, and a high flow capacity (Cv value), enabling it to drive multiple actuators or large cylinders simultaneously.
• ​​Compact & Modular for Easy Integration​​The valve body is compact and supports manifold mounting. Multiple valves can be grouped together with a unified air supply and wiring, saving space and simplifying maintenance.
• ​​Wide Voltage Compatibility & High Durability​​The coils support various standard voltages like DC24V/AC220V (the -A suffix may indicate voltage code). The precision-ground spool and sleeve, coupled with wear-resistant sealing materials, ensure a lifespan of millions of cycles.
• ​​Manual Override & Dual-Color Indication​​Includes a manual override (push-pull type) for easy commissioning, maintenance without power, or emergency intervention. Dual LED indicators show the status of each coil, making fault diagnosis clear at a glance.

​​Typical Application Scenarios​​

• ​​Double-Acting Cylinder Control:​​ Precisely controls cylinder extension and retraction for clamping, pushing, lifting, and other applications requiring position holding.
• ​​Safety Interlock Systems:​​ Used in safety control circuits requiring dual-signal confirmation, such as two-hand start systems or safety door interlocking.
• ​​Automated Production Lines:​​ Stations requiring stable position memory in packaging, assembly, and sorting equipment.
• ​​Pneumatic Manipulators:​​ Drives grippers and rotary units to execute complex motion sequences and maintain states.

​​Technical Parameters (Typical Values)​​

• ​​Valve Configuration:​​ 5-port, 2-position (5/2-way)
• ​​Port Size:​​ G1/4″ (Common)
• ​​Operating Pressure Range:​​ 0.15 ~ 0.8 MPa
• ​​Coil Voltage:​​ DC24V (Common)

​​Summary​​With its dual-coil latching and high-flow drive characteristics, the VP344R-5DZ1-A dual-solenoid valve serves as the ​​”Intelligent Control Hub” for demanding pneumatic systems.​​ It not only enables precise control of complex pneumatic circuits but also provides a solid foundation for system safety and energy-efficient operation through its power-off memory function.​​Choosing the VP344R-5DZ1-A means selecting a directional control core that is fast-responding, stable, safe, and reliable!​​
