BELIMO® Characterized Control Valve, 3/4 in Nominal, FNPT Connection, 3-Way Ways/Position, 600, 200 psi, 4.7 Cv Flow Coefficient (Cv), Stainless Steel Stem, Stainless Steel Trim, EPDM Packing, PTFE Seat, EPDM Seal, Forged Brass, Nickel-Plated, Non-Spring Return Actuator, Modulating Control, Screw Terminal with 1/2 in Conduit Connector Electrical Connection, 24 VAC/VDC, 50/60 Hz, 5 VA, NEMA 4X, IP66, IP67 Enclosure, Maintenance-Free Service, 3.5, 0.6 W Power Consumption, 90 s Run Time, 0 to 250 deg F, 2.73 in L
Belimo's unique characterized control valve (CCV) is very different. A special characterizing disc inside the valve gives it an equal percentage characteristic which is comparable with that of a globe valve of the same nominal size. The flow (the Cv value) is reduced to the required value by a combination of the hole in the ball and the shaped aperture in the disc. The increase in flow as the valve is opened is very slow and controlled.
- VAV box reheat coils and bypass loops
- This valve is suitable for use in a hydronic system with variable flow
- Equal percentage flow characteristics
- A port as stated in chart B-port 70% of a to AB Cv flow rating
- 75 deg controllable flow range
- 0% for a to AB leakage
- The need for multiple pipe reduction is usually eliminated
- Better control prevents hunting of the control loop, increasing life span of actuator and valve
- Thermal isolating adapter between flange and actuator
- Easy direct coupling of actuator with a single screw
- Perpendicular-mounting flange and square drive head eliminate lateral forces on the stem
- Blowout-proof stem with thrust bearing PTFE disc and double O-ring design for long service life
- Non-corroding chrome-plated brass or stainless ball
- Vent holes reduce condensation build-up
- Forged brass valve body no pin hole leaks
- Characterizing disc made of Teflon® known for excellent strength and chemical resistance
- PTFE seats with O-rings provide constant seating force against the ball and reduce torque requirement
- Actuator can be mounted in four different positions
- Chilled or hot water, up to 60% glycol fluid
- External pushbutton manual override
