Single orifice air valve

Single orifice air valve

Product catalog summary

Description
The Series F1 10 single orifice air valve includes a 1/4 turn ball valve with a lockable square cap, a built-in operation controller, and is constructed from ductile iron with a powder epoxy and cataphoresis coating. It features stainless steel bolts and operates at a minimum pressure of 0.1 bar, conforming to the EN 1074 - 4 standard.

Technical Data
The valve is available in two types: Type 102 (PN 16 and 25) and Type 150 (PN 25 and 40), with sizes ranging from DN 40 to 80 and a 1” male BSP model. It supports a maximum working pressure of PN 16, 25, and 40, and operates within temperature limits of +1 °C to +70 °C. Flange drilling complies with EN 1092-2 and ISO 7005-2 standards, and the BSP profile thread adheres to ISO 228-1 and NF E03-005 standards.

Applications
This air valve is suitable for drinking water networks, fire protection networks, and irrigation networks.

Tests
The product undergoes full testing in accordance with ISO 5208-2 standards.

Operation
The valve operates by closing the evacuation orifice when no air is present, due to water pressure on the float. If air pockets fill the valve, the float moves downwards to open the orifice, allowing air to escape. The built-in stopcock facilitates isolation for maintenance.

Installation
The unit should be installed vertically at the highest point, along the flow direction, downstream of control valves on descending pipelines, and at regular intervals along ascending/descending pipelines, at least every 500 meters.

Lockable Square Cap
The lockable square cap prevents untimely operations by allowing the isolating valve to be locked in an open or closed position.

Discharge Capacity
Type 102 and 150 valves have varying orifice sizes and flow rates, with Type 102 (PN 16) having a 1.8 mm orifice and a flow rate of 0.50 l/s, and Type 150 (PN 25) having a 2.5 mm orifice and a flow rate of 0.95 l/s.
