Overview
Two-way, high pressure,Fan Coil zone valves (VU52 and VU523), are used to control flow of hot/chilled water in commercial HVAC equipment such as fan coil units, terminal reheat coils and convectors. IMPORTANT: Not for use in systems containing dissolved oxygen
Features
- Compact construction for easy installation.
- Fits under the cover of most baseboard convectors with actuator fitted to valve body.
- VU52 and VU53 provide 2-way, straight-through control of water.
- Available in normally closed (VU53) or normally open (VU52) configurations.
- 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.
- Available with NPT end connections for iron or steel piping.
