Fan Coil Valves
VU54 Three-way Fan Coil Valves
Three-way fan coil zone valves are used to control hot or chilled
water in commercial HVAC equipment such as fan coil units,
terminal reheat coils and convectors.
• Compact construction for easy installation.
• Fits under the cover of most baseboard convectors with actuator
tted 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 ow curve.
• Choice of NPT end connections for iron or steel piping.
