Series 3PBV Automated Ball Valves - 3-Way Plastic
Specifications - Installation and Operating Instructions
Bulletin V-16
®
The Series 3PBV is ideal for mixing or diverting services in industrial,
chemical, turf and irrigation, and pool and spa applications, as well as
for use with potable water. The valve features a 3-seat design for efficient
automation, reinforced TFE seats and EPDM seals for longer life, and an
all PVC construction for heavyweight durability at a lightweight cost.
Valves also come standard with field selectable NPT or socket process
connections.
The 3PBV is an economical automated valve package with either an
electric or pneumatic actuator. Electrically actuated models are
weatherproof, NEMA 4, powered by standard 115 VAC supply, and are
available in either two-position or proportional control. Two-position
actuators use the 115 VAC input to drive each of the valve ports open
or closed, while the modulating actuator accepts a 4 to 20 mA input for
infinite valve positioning. Actuator features include thermal overload
protection to withstand stall conditions, visual position indication and a
permanently lubricated gear train.
The pneumatic double acting actuator uses an air supply to drive each
of the actuator ports. Spring return pneumatic actuators use the air
supply to drive the valve stem one direction, and internally loaded springs
return the valve to its original position. Also available is the SV3 solenoid
valve to electrically switch the supply pressure between the air supply
ports. Actuators are constructed of anodized aluminum and are epoxy
coated for years of corrosion free service.
