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. FeaturesVCB 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
• Twist lock mount for actuator head. Actuator can be
installed after plumbing work has been completed to
• 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
VC series Actuator
• All actuators are interchangeable and suitable for valves
½"~1". This provides installation flexibility with minimum
• Actuator is powered by a unidirectional motor and crank
• 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
• The actuator is constructed for moisture and humidity
