TAC (Formally Tour & Andersson Control) has released the new TAC Ventatm line of control valves for steam, hot water, and chilled water systems. These valves are the first HVAC control valves to meet IEC 534 compliance standards. This valve is extremely quiet with an excellent low leakage rating of less that .02%. The stainless stem and trim, self-cleaning robust design provide for a very long life span with minimal maintenance requirements. The valve is also compatible with glycol mixtures for low temperature applications.

The EQM design provides very accurate control over the total flow range of the valve.
Other features are stainless seat and trim, sweat and NPT union connections, and high temperature packing kit for high-pressure steam. The Ventatm line of control valves are available in sizes from ½" to 2", either two-way or three-way configuration.

The TAC Ventatm valve is compatible with existing TAC actuators and linkages and the new TAC Fortatm combination actuator - linkage. The TAC Fortatm actuator has selectable signals, direction of travel, and travel speed, 1/3 - 2/3 control from a single control signal, and can easily adapt to most any existing control valve.
