Why Choose ATLAS Three-Way Brass Valves?

ATLAS three-way brass valves are designed to mix fluids or divert flow between branches in hot- and cold-water HVAC installations. With a suitable actuator, proportional control helps adjust flow to demand in air handling units, boiler rooms and heat pump circuits.

An internally threaded brass body and stainless steel ball provide a durable structure. DN20, DN25, DN32 and DN40 body options accommodate different installation sizes. A model suitable for the required mixing or diverting duty can be selected for the hydraulic circuit.

The product table lists Kvs values of 6.3 m³/h for DN20, 10 for DN25, 16 for DN32 and 25 for DN40. These data support selection based on design flow and pressure loss rather than pipe diameter alone.

Key benefits

Mixing or diverting functions in suitable models.
Brass body, stainless steel ball and DN20–DN40 options.
Proportional control with a suitable actuator and model-specific Kvs data.

The Atlas three-way motorised ball control valve is designed for use in HVAC systems. It can be used in systems such as air handling units, boiler rooms or heat pumps. With its PN10–PN16 body, it operates reliably across a wide temperature range and withstands high pressures.

There are also series available for use as diverting/directing valves in industrial or specialised applications.
