AAP Bronze Variable Balancing Valve, 1/2"

This AAP variable balancing valve is a variable orifice bronze double regulating valve with test points, Fig. 9505. It has female threaded ends and is supplied in 3 sizes, 1/2" (15mm) to 1" (25mm). A balancing valve sets the flow in a circuit and lets it be checked. The two test points on the body let a manometer read the pressure difference across the valve, and the flow is worked out from that reading and the handwheel position using the Kv table.

It gives a working pressure of 2,500 kPa (25 bar) up to 80°C and 2,000 kPa (20 bar) up to 100°C, and a working temperature of -10 to 130°C. Use below 0°C is only for water with antifreeze added and use over 100°C only for water with additives that stop boiling, and gives no pressure rating above 100°C.

Where this product is used
