Description
2" Modulating WRAS Motorised Stainless Steel Ball Valve – ABV20S/9M
The ABV20S/9M is a premium 2" WRAS approved modulating motorised stainless steel ball valve designed for accurate proportional control of potable water flow in commercial and industrial applications. Combining a full-bore 304 stainless steel WRAS approved ball valve with a precision electric actuator, it provides smooth modulating control, integrated position feedback and exceptional reliability for building management systems, water treatment and process control.
Supporting 4–20mA, 0–5V and 0–10V control signals, the ABV Series is ideal for applications requiring accurate flow regulation rather than simple ON/OFF operation.
