SMC AV4000-F04B-5YZB-A
SMC AV2000/3000/4000/5000-A Soft Start Valve
Product Description
The SMC AV2000/3000/4000/5000-A Soft Start Valve series is designed to ensure a smooth and controlled start-up of pneumatic systems. This valve gradually raises the initial pressure in an air system, preventing sudden surges and potential damage. It also allows for quick exhaust by cutting off the air supply, ensuring rapid system depressurization.
The AV series includes air-operated types (AVA series) and lockout types (AVL series), offering flexibility for various applications. The integrated silencer reduces noise and simplifies installation, while the improved flow rate characteristics enhance performance by up to 2.3 times. The valve's energy-saving design ensures no air flow when the main valve is switched, reducing operational costs.
Key features include a manual override with a push-turn locking slotted type, a light/surge voltage suppressor, and compatibility with various electrical entries such as DIN terminals and M12 connectors. The valve is compliant with IP65 standards, ensuring reliable operation in demanding environments.
Applications include pneumatic systems requiring controlled pressure build-up and quick exhaust capabilities, making it ideal for industrial automation, manufacturing, and process control.
