Overview V5013B is a mixing three-way valve. V5013C is a diverting three-way valve. These valves provide proportional or two-position control of hot/chilled water in closed loop heating/cooling systems - offered in sizes 2 1/2 in. through 6 in. Features Not suitable for combustible gases. Valves utilize direct mounting valve actuators, Q5020/Q5022 linkages with Direct Coupled Actuators, or Pneumatic Valve Actuators to operate the valve. Constant total flow through full plug travel. Stainless steel stem prevents corrosion. Class IV (0.01% of Cv) Leakage Rating.
