Fan Coil Valves

VU54 Three-way Fan Coil Valves

Three-way Fan Coil Valve, the VU54 high pressure zone valves are
used to control the flow of hot or chilled water in commercial HVAC
equipment such as fan coil units, terminal reheat coils and
convectors. IMPORTANT These valves are not for use in systems
containing dissolved oxygen.

• Compact construction for easy installation

• Fits under the cover of most baseboard convectors with
actuator fitted to valve body

• VU54 provides three-way diverting control of water

• 300 psi (2,000 kPa, PN20) operating pressure rating

• Patented ball seal provides long service life, soft close off

• Triple O-ring seal provides three lines of defense against corrosion
and water leakage around drive shaft

• Quick opening flow curve

• Choice of NPT end connections for iron or steel piping
