Controls hot and/or chilled water for VAV terminal units, fan coil units, small reheaters and recoolers in electric/electronic temperature control systems. Used with the M6410 (non spring return)/M6435 (spring return) small individual room controller 3-position floating electronic linear valve actuator or M7410 (non spring return)/M7435 (spring return) selectable 0 to 10 Vdc or 2 to 10 Vdc electronic actuator, or MP958 (2000 series valves only) pneumatic valve actuator.
Larger valves (1 to 1-1/2" ) are pressure balanced, which results in higher close-off pressures.
Long stroke allows wider range of control.
Soft valve seat provides low leakage rate.
Inserts for 1/2 and 3/4" valves are changeable without draining valve when used with an insert replacement tool.
