4 PopTopTM Convenience – Easy to Install Clearance1 inchOne-handed removal orengagement of the actuator to thevalve bodyPush lever to releaseNo tools or linkages requiredOnly 1” clearance neededto remove actuatorManual OverrideRelease leverThe PopTop allows installers to remove the actuator from the valve with one hand in seconds. No screws to hassle with…..just a release lever. Only 1” of clearance to the top of the actuator is necessary to remove or install the actuator.Now, valves can be shipped straight to a mechanical for assembly into piping packages, while the actuators are wired up on site. When the piping arrives, just snap the actuator to the valve.For wholesalers, valves and actuators can be stocked separately and easily combined to create the desired combinations on the spot. The number of SKUs and amount of inventory is much less than stocking many combinations of assemblies, increasing inventory turns.Since the valves and actuators were designed as a system, torque requirements for the actuators were minimized resulting in a small, compact actuator.
6 Oversize Wrench Flats – Easy to Install Contractor friendlyKeep threads and flatsfrom deformingStands up to abuse inthe fieldVBB/VBSOne aggravation for anyone who has used a wrench to tighten a connection to a pipe is when you aren’t able to get a good grip with the wrench. The wrench slips off, or because you need to try to grip the valve so hard you actually deform the flats or threads of the valve.VBB/VBS valves were designed with extra large wrench flats to make installation easier – and less aggravating.Competitor

The result is optimal performance and unique features.The VBB/VBS family addresses applications requiring ½” or ¾” valves, which represent approximately ¾ of ball valve applications. Schneider Electric’s Vx-2000 Series of ball valves is available for applications requiring valves >3/4”The VBB/VBS valves and actuators are completely interchangeable, assuring compatibility.Chrome Plated Brass Ball w/SS Stem (VBB)Stainless Steel Ball Valve & Stem (VBS)Spring Return On/Off (2 Position) Normally Open or Normally Closed
8 Field Configurable Input Signal Options Configure proportional actuators at point of sale or in the fieldNo special, expensive programming tools requiredChoice of 0-10 Vdc, 0-5 Vdc, 5-10 Vdc or 4-20 mADirect Acting or Reverse ActingGreater flexibility, less inventory, fewer sku’sWhen proportional control is required, there are a variety of input signal ranges that could be used. Proportional actuators for the VBB/VBS Series can have the desired input signal selected and either direct or reverse acting in the field using internal jumper connections. Being able to chose the control signal, only one part number is necessary, so SKUs and inventory are minimized.(Left picture is for a proportional NSR actuator; right picture is for proportional SR actuator).Jumpers
9 A high level of control for your applications The VBB/VBS Series of ball valves and actuators has been designed with a “system” approach; i.e. the valves and actuators were designed at the same time specifically for use as an assembly. The result is optimal performance and unique features.The VBB/VBS family addresses applications requiring ½” or ¾” valves, which represent approximately ¾ of ball valve applications. Schneider Electric’s Vx-2000 Series of ball valves is available for applications requiring valves >3/4”The VBB/VBS valves and actuators are completely interchangeable, assuring compatibility.
10 300:1 Rangeability = Better Control Rangeability is a design characteristic of a valve defined as the ratio of the maximum controllable flow to the minimum controllable flow.For a given valve size, the higher the rangeability, the better because the valve can control a smaller flow rate.
11 Better Control 300:1 Rangeability Better control at low flow Greater control of temperatureMore stable systemLow flow conditions are important for efficient system operation and comfort.Rangeability is a characteristic of the valve that indicates how well the valve is able to control flow in this critical situation. The greater the Rangeability, the better the control at low flow.Rangeability of ball valves tends to be very high – over 200:1The desired state is “equal percentage” flow curve. Flow through the valve offsets the heat transfer of the coil so the net effect is a linear relationship.Example:Maximum controllable flow through valve = 100 gallons/min (gpm)- Minimum controllable flow through valve = 2 gallons/min (gpm)Rangeability = 100/2 = 50/1
13 Exploded View – VBB/VBS Design Less torque required to move ball allows use of smaller actuatorsUnique, patented designPTFE seals allow for lower friction and higher temperature resistance.With the addition of wave springs, the PTFE seals continually adjust for wear and contamination.Most ball valve manufacturers utilize PTFE seals and anti-blow out (resistant) stems. Our spring design allows the seals and ball to float, resulting in lower and more consistent torque requirements. This allows us to achieve ANSI IV leakage while utilizing a lower torque (smaller footprint) actuator.
14 Reliability Assured 100% inspected AND water tested under pressure Fewer call-backsTrouble-free performanceHigh quality is paramount. Schneider Electric VBB/VBS valves are not only 100% inspected, but also 100% tested with water under pressure.That’s why you can be assured of trouble free performance with VBB/VBS ball valves. Other manufacturers may inspect, but not all water test.
16 Valve leakage, why is it important? If you don’t control at close-off, you don’t have control.Maximum leakage shown per ANSI specification.ANSI ANSI ANSI 4*MAX Leakage for 4.5 Cv valve, 3 psi Pressure Drop in 15 minutes
17 DuraDrive ball valves with ANSI IV rating ANSI IV ratedboth A and B portsfor 3 –way valvesWhen the valve is closed, the desire is that no water should flow through the valve. But under pressure, some water can get through. The ANSI rating tells us the maximum amount of leakage that could occur.Unintended flow through the valve wastes energy being circulated through the system, and adding heat or cooling an area when it shouldn’t.A change in ANSI ratings between III and IV is a factor of 10 in leakage at close-off.
