SMC Pneumatic Soft Start Valve Maximum Operating Pressure 1 Mpa Temperature Range 0°C to 60°C AV4000-04-5DZ-Q

SMC AV4000-04-5DZ-Q Pneumatic Soft Start Valve is designed for precise pneumatic system control in industrial applications. It enables gradual pressure increase upon start-up and rapid air exhaust on shutdown, enhancing system safety and longevity.

The valve offers a maximum operating pressure of 1 Mpa and functions reliably within a temperature range from 0°C to 60°C. It is constructed from robust materials including the cap and body, while the piston and slide are made of NBR, ensuring durability in demanding operating conditions.

This combined soft start and dump spring return valve supports manual operation of air supply and exhaust, with the ability to lock in the exhaust position. It is fully compatible with the SMC modular series FRL, allowing seamless integration into existing pneumatic systems.

Additional features include a maximum working pressure of 10 bar and a proof pressure rating of 15 bar. The valve is equipped with gauge port sizes ranging from G 1/4 to G 1/2. The low power solenoid operates efficiently at 24Vdc with a power rating of 1.8W.

For noise reduction when utilizing the dump valve facility, it is recommended to fit a silencer to the relieving port. Soft start valve gradually increases pressure during system start-up. Combined soft start and dump spring return valve enables manual air supply and exhaust operation.
