2-way 3-way On / Off Mixing Modulating AHU – FCU Valves
Application:
Honeywell VCBM series FCU balancing modulating valve is a new type of valve for FCU temperature control in HVAC hydronic system. It combines the dynamic balancing and electric modulating functions in one unit, It has a coherent structure, high flow control precision and stability. VCBM series FCU balancing modulating valve can also be used in zoning control and other applications when it has the same demand. VCBM series FCU balancing modulating valve is a self balanced flow and modulating control valve, used in 2-way modulating controls, of flow rate 0.28 to 2.3 m3/h. It consists of a VC79 series actuator and a VCBM series flow control valve with a replaceable modulating valve insert and a constant flow balancing cartridge.
Features
- Integrated dynamic balancing and electric modulating controls in one unit
- High accuracy constant flow control. Within control range, differential pressure fluctuation across the valve will not affect flow rate
- No calibration required
- Quick and easy installation
- Integrated valve body reduced installation space
- Brass (Chrome) plated dynamic cartridge resists corrosion & long service life
- Twist lock mount for actuator head. Actuator can be installed after plumbing work has been completed to prevent damage
- Valve body is made of cast bronze which is not subject to dezincification (due to oxygen dissolved in water)
- The actuator provides sinusoidal piston travel action for perfect flow characteristic curve, to eliminate water hammer synchronously in most applications.
