VQZ3550-5M1: Compact, Efficient, Precise Flow Control! Pilot-Operated 5-Port Solenoid Valve Empowers General Automation

In automated machinery, rapid and reliable directional control of pneumatic actuators (such as double-acting cylinders) is a core requirement. The VQZ3550-5M1 is a versatile pilot-operated 5-port solenoid valve. With its compact structure, efficient pilot control, and stable performance, it serves as a fundamental and reliable choice for driving cylinders and achieving directional control. Core Product Advantages

• Efficient Pilot-Operated Control:​ Utilizes a pilot-operated structure, where low-power electromagnetic force controls the high-flow main air path. This ensures low power consumption and fast response, making it suitable for frequently started/stopped applications.
• Single Solenoid with Spring Return:​ Features single-coil control (5M1 likely indicates single solenoid). The spool shifts when energized and automatically returns to its initial position via a spring when de-energized. This high-safety design is ideal for applications requiring a fail-safe return.
• Compact, Modular Design:​ The valve body is compact in structure and supports manifold mounting. Multiple valves can be densely arranged on a common air manifold, unifying the air source and wiring to save space and simplify maintenance.
• Manual Override Function:​ Includes a manual override button (push-pull type) for convenient commissioning, maintenance during power-off, or emergency intervention.
• Wide Voltage Compatibility:​ The coil supports various standard voltage specifications such as DC24V/AC220V, adapting to different electrical control environments.

Typical Application Scenarios

• Automation Equipment:​ Controlling the reciprocating motion of double-acting cylinders on packaging machines and assembly lines.
• Clamping Systems:​ Driving the action control of pneumatic grippers, rotary actuators, and other actuators.
• Material Handling:​ Driving cylinder control on robotic arms, conveyor belts, etc.
• General Industrial Equipment:​ Widely used in various mechanical equipment requiring pneumatic directional control.

Technical Parameters (Typical Values)

• Spool Configuration:​ 5-port, 2-position (5/2-way, for controlling double-acting cylinders)
• Port Size:​ G1/4″ (common)
• Operating Pressure:​ 0.15 ~ 0.8 MPa
• Operating Temperature:​ -5℃ ~ +50℃ (medium and ambient temperature)
• Protection Rating:​ IP65

Closing Summary With its pilot-operated high efficiency, compact design, and reliable spring-return function, the VQZ3550-5M1 solenoid valve serves as the “cost-effective control hub” in automated pneumatic systems. Its stable performance ensures precise actuator movements, making it an ideal foundational component for building reliable, low-cost pneumatic control systems. Choosing the VQZ3550-5M1 means choosing a responsive, stable, and cost-effective core for directional control!
