Schneider Electric VBB/VBS Series TAC® DuraDrive™ Ball Valve Actuators

Schneider Electric
TAC® DuraDrive™ Ball Valve Actuators
VBB/VBS Series

The Schneider Electric DuraDrive VBB/VBS series ball valves combine a unique, low force valve design with a compact actuator to create an assembly that is faster and easier to install than any other ball valve assembly in the industry. The VBB/VBS series products accept floating and proportional control signals from a DDC system, controller, or thermostat for control of hot or chilled water, or solutions of up to 60% glycol. The assemblies consist of direct-coupled TAC DuraDrive floating or proportional spring return or non-spring return actuators mounted on 2-way ½” or ¾” (15 mm or 20 mm) VBB or VBS series valve bodies. The VBB Series ball valves include a chrome plated ball and nickel plated stem and the VBS Series ball valves include a stainless steel ball and stem.

The proportional TAC DuraDrive actuators can accept four different input signal ranges, as well as direct and reverse input signals. Actuators are also available that provide 10’ (3.05 m) plenum rated cable and conduit connectors to accommodate the specific wiring requirements of all projects.

The ball valves and actuators can be purchased separately or ordered as complete valve and actuator assemblies, and are easily installed in the field. The ability to easily combine any actuator on any VBB/VBS valve body allows many different valve assembly combinations to be configured using just a few different actuators and valve bodies. The interchangeable valves and actuators provide maximum flexibility in the field while minimizing inventory requirements.

• The fastest and easiest actuator to install and service in the industry
• Compact, low clearance actuator suitable for confined area applications
• Jumper selectable proportional actuator input signal ranges
• Actuator models with integral 10’ (3.05 m) plenum rated cable and conduit connector
• Actuator models with quick connect “screwless” lever terminal blocks
• Manual operator with position indication
• Normally open, normally closed, and non‑spring return models
• Characterized equal percentage models for accurate, stable control
• Full port models for high flow applications
• Heavy duty, “pipe-fitter approved,” wrench flats prevent end connections from rounding and eliminate poor wrench gripping
• Very low ANSI Class IV (0.01%) seat leakage
• Chilled and hot water applications (up to 60% glycol)
• Chrome plated ball with nickel plated stem and stainless steel ball and stem models
• Rugged 600 psi static pressure rating Screwed NPT and Metric Rp end connections
• Optimized easy turn ball valve design
• Blow out proof stem with dual O-rings
