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 heavy weight
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.
