1/2 to 1 Inch WRAS Approved 3 Way Motorised Stainless Steel Ball Valve with Modulating Control – ABVS3TL/9M
The ABVS3TL/9M is a WRAS approved 3-way motorised stainless steel ball valve with precision modulating control, designed for accurate flow regulation, mixing and diverting of potable water and compatible fluids. Supporting 4–20mA, 0–5V or 0–10V control signals, it provides smooth proportional valve positioning for Building Management Systems (BMS), HVAC, water treatment and industrial process control.
Manufactured from 304 stainless steel with WRAS approved PTFE and EPDM seals, the valve combines excellent corrosion resistance with high-resolution actuator control. Available with either L-Port or T-Port flow configurations, together with integrated position feedback, actuator status output and optional failsafe return, it provides an ideal solution for automated water and process control systems.
