Smc Pneumatics SY5140-5DZ-02T Pilot Operated Valve 24V

Product Description

The SMC PNEUMATICS SY5140-5DZ-02T is a single solenoid pilot operated directional control valve designed for pneumatic systems requiring precise flow management. Rated at a 0.7 Cv flow coefficient, it features a 5-port, 2-position configuration with spring return action, making it well suited for controlled actuation cycles where a defined fail-safe position is required. The inlet connection is 1/4 inch NPT. Operating voltage is 24 volts, compatible with both 24V AC and 24V DC control circuits. Licensed HVAC technicians, industrial maintenance professionals, and pneumatic system integrators are the primary installers of this valve type.

This valve is commonly used in commercial and industrial pneumatic control applications where directional airflow must be switched reliably. The spring return mechanism ensures the valve defaults to a known position upon de-energization, which is critical in automated equipment, process control panels, and pneumatic actuator circuits. Its compact design and standard NPT porting make it straightforward to integrate into existing pneumatic manifold or inline plumbing configurations.

Key Features

• 0.7 Cv flow coefficient for controlled pneumatic flow capacity
• 5-port, 2-position configuration with spring return for fail-safe operation
• Compatible with 24V AC and 24V DC control circuits
• 1/4 inch NPT inlet connection for standard pneumatic plumbing
• Single solenoid pilot operated design for reliable directional switching
• Operating temperature range from -10 degrees C to 50 degrees C

Compatibility

Designed as an OEM-style replacement or direct-install component for pneumatic directional control systems requiring a 5-port, 2-position single solenoid pilot operated valve with 1/4 inch NPT porting and 24-volt coil actuation.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize the pneumatic circuit and de-energize all control power before removing or installing this valve. Verify supply voltage matches the coil rating before energizing. Ensure all NPT threaded connections are sealed with appropriate thread sealant compatible with compressed air service.
