## Summary description

Afriso AAV 300 (model 1730000) is an anti-freeze/safety valve with G1 1/4" connection, PN10 rated pressure and a flow coefficient Kvs of 70 m3/h. Designed for protection against freezing and pressure relief in heating and industrial fluid systems, it provides reliable flow control and system safeguarding where high nominal flow is required.

## Long description

Afriso AAV 300 is an anti-freeze and safety valve designed for heating and industrial fluid systems that require high nominal flow. With a G1 1/4" threaded connection and PN10 rated pressure class, the valve provides dependable protection against freezing and overpressure while enabling rapid discharge when conditions demand. The valve's Kvs value of 70 m3/h indicates a high flow capacity suitable for larger circuits and systems where maintaining fluid movement and system safety is critical.
Advantages
The Afriso AAV 300 combines anti-freeze protection and pressure relief in a single compact unit, reducing the need for multiple components. Its robust design supports PN10 system pressures and a high Kvs flow coefficient, which ensures efficient fluid evacuation when actuated. Threaded G1 1/4" connections provide straightforward installation into existing piping. The device is intended for continuous readiness and reliable operation under typical heating and industrial environments.
Suitable for
 Heating systems where freeze protection is required
 Industrial fluid circuits requiring overpressure safety
 Large-diameter or high-flow installations needing rapid discharge
 Replacement or upgrade of existing safety/anti-freeze valves with similar connection and pressure rating
Key specifications
 Connection: G1 1/4" threaded
 Pressure rating: PN10 (suitable for systems up to the nominal pressure)
 Flow coefficient: Kvs 70 m3/h
 Function: anti-freeze protection and safety/pressure relief
 Application medium: heating fluids and compatible industrial liquids
How to use
Install the valve into the piping at a location where it can effectively protect the system from freezing and relieve excess pressure. Ensure thread sealing is applied according to the system's standards and that the valve orientation matches the flow direction marked on the body. Commissioning should include a pressure check at PN10 conditions and a functional test to verify that the valve opens and discharges at the expected conditions. Maintain clear access for inspection and periodic testing as required by local regulations or system maintenance schedules.
Usage recommendations
Use the Afriso AAV 300 in systems with compatible fluids and within the PN10 pressure limit. For reliable operation, follow manufacturer's mounting instructions, perform routine functional tests, and avoid corrosive or particulate-laden media that could impair valve performance. When replacing an existing valve, confirm that thread size, pressure class, and Kvs are appropriate for the application.
