KMC Controls Diverting Zone Control Valve Cv

KMC Controls diverting zone control valves are three-way globe valves. They regulate the flow of hot or chilled water in HVAC hydronic systems. Typical uses include VAV terminal unit reheat coils, fan coil units and induction units. Pneumatic versions also suit finned tube convectors and cast iron radiators. The line pairs a valve body with your choice of actuator, so the same diverting design works with pneumatic or electric control strategies.

Key Features:

• Three-way diverting design: as the valve stem moves, flow through one outlet port increases while flow through the other decreases. This lets the valve divert water between a coil and its bypass.
• Compact construction: the small footprint makes installation easy in tight enclosures.
• Actuator options: pneumatic models and electric models are available. Electric options include tri-state/floating, proportional and two-position spring-return fail-safe actuators.
• Fail-safe positioning: the actuator determines the fail position of the valve. Spring-return and pneumatic models return to a defined position on loss of power or signal pressure.
• Durable pneumatic actuators: they have a glass-filled nylon housing and a neoprene diaphragm.
• Easy serviceability: replacement actuators can be installed on the valve bodies without tools.
• Position indication and manual override: these are provided on the spring-return electric actuators.
• Mixing capability: these valves are diverting valves, but they can be used as mixing valves when piped in the return flow within the published pressure limits.
• Female NPT connections: they give a secure threaded connection to the piping.

Choose the flow coefficient (Cv), line size, actuator type and fail position that match your coil and control system. These KMC Controls zone valves give reliable, repeatable water-flow control in commercial HVAC zone applications.
