AVENTICS AS3-SOV Soft Start / Shut-off Valve

Description

The AVENTICS 0821300967 is a 3/2 soft-start and shut-off valve from the AS3 series of air preparation units. It is designed to safely and gradually build up pressure in a pneumatic system, preventing abrupt and potentially dangerous actuator movements. When de-energized, it provides a quick exhaust function, rapidly venting the downstream system. This component is essential for machine safety and smooth operational start-ups.

Application

This valve is typically used as the main shut-off valve in a pneumatic FRL (Filter, Regulator, Lubricator) assembly. It's ideal for applications requiring controlled pressurization after a system stop or during initial machine power-up.

Country of Origin

Made in Germany.

CO2 Impact

Opting for a refurbished pneumatic component like this one prevents the emission of approximately 7.2 kg of CO2 compared to manufacturing a new one.

FAQ

No, this is the main valve body (part number 0821300967). The solenoid pilot valve must be ordered separately according to the required control voltage (e.g., 24V DC).

The brass adjustment screw on top is a needle valve that controls the pressurization time. By turning it, you can regulate how quickly the downstream pressure builds up, allowing for a 'soft start' of pneumatic actuators.

Yes, the AS3-SOV is designed for this purpose. When the pilot signal is removed, the valve quickly blocks the inlet pressure and rapidly exhausts the downstream system (port 2 to 3), which is a key function for safety-related pressure dumping. However, always verify the required safety performance level (PL) for your specific application.
