Fan Coil Valves
VU52; VU53 Two-way Fan Coil Valves
Two-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. Not for use in systems
containing dissolved oxygen.
• Compact construction for easy installation.
• Fits under the cover of most baseboard convectors with actuator
tted to valve body.
• VU52 and VU53 provide 2-way, straight-through control of water.
• Available in normally closed (VU53) or normally open (VU52)
congurations.
• 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.
• Available with NPT end connections for iron or steel piping.
