SMC Pneumatic Solenoid Valve Start-Up Valve G Series AV 1/2 in Threaded Port, 24V dc, 4945 L/min Flow AV4000-F04-5YZB-A

SMC AV4000-F04-5YZB-A Pneumatic Solenoid Valve Start-Up Valve G Series AV, 24V dc, 1/2 inch threaded port with a high flow rate of 4945 L/min, is designed for industrial pneumatic control applications. This valve provides soft start control for compressors and actuators, preventing airflow when the main valve is de-energised and improving energy efficiency during system start-up.

The valve features a robust die cast aluminium body paired with durable Nitrile Rubber (NBR) seals, ensuring reliable operation within a pressure range up to 1 MPa. It supports operation within a temperature range of 0 °C to 50 °C, making it suitable for various industrial environments. The G-threaded female ports allow easy integration with existing pneumatic systems.

This single solenoid valve incorporates a low power solenoid consuming only 0.35 watts, minimizing electrical load while maintaining effective operation. The integrated silencer reduces both installation time and audible noise, contributing to a safer and more comfortable workplace. The electrical connection is provided via a DIN connector designed for 24V dc control circuits, which includes light and surge suppression for stable switching.

Typical applications include soft start control of pneumatic compressors, sequencing air supply to large pneumatic cylinders, automated manufacturing lines requiring shock reduction during startup, and machine safety interlocks in production cells. The valve’s design allows for standalone mounting and retrofitting within existing G-threaded pneumatic systems.

The unit’s compact dimensions of approximately 170 mm length, 98 mm height, and 52 mm width enable versatile installation options without occupying excessive space. The valve is not certified for hazardous area use but complies with CE standards, ensuring quality and safety.

Supports large volume air flow with a maximum rate of 4945 L/min. Durable construction including die cast aluminium body and NBR seals. Standard G 1/2 threaded female ports ensure compatibility with common pneumatic fittings.
