Hotowell VCB series FCU balancing control valve is designed to control the flow of hot and/or chilled water in zoning systems applications. This is a self balanced flow control valve used in 2-way on/off controls for flow rate ranging from 0.28 to 2.3 m3/h.
VCB series combines the dynamic balancing and electric on\off functions in a single valve body. It consists of a VC series actuator, a control valve insert and a constant flow balancing cartridge in a valve assembly.

>> Features
VCB Series Control Valve
• Combination of dynamic balancing and electric on\off function in one body
• Every loop automatically limited to design flow
• Simplified pipe calculation
• Quick and easy setup
• No balancing work required
• Integrated valve body reduced installation space
• Stainless steel valve stem resists corrosion & long service life
• Twist lock mount for actuator head. Actuator can be installed after plumbing work has been completed to prevent damage
In this balanced valve design, the control cartridge moves up and down, across water flow. The actuator
provides sinusoidal piston travel action for soft shut-off and opening to eliminate water hammer in most applications.
>>VC series Actuator
• All actuators are interchangeable and suitable for valves ½“~1“. This provides installation flexibility with minimum inventory requirement.
• Actuator is powered by a unidirectional motor and crank arm mechanism.
• Motor only operates for few seconds each cycle, power consumption is minimal and motor life greatly extended.
• Locking tab secures actuator to valve body. To remove the head, depress the tab and then rotate the actuator by 45o.
• The actuator is constructed for moisture and humidity resistant material.
