Safety/anti-freeze valve Afriso AAV 300 1730000 G1 1/4" PN10 Kvs 70 m3/h

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.
