The pneumatic actuators on the BVP/BVPS80 and
BVP/BVPS70 Series offer the latest technology for
pneumatically actuating BV80 Series ball valves with
NPT threads and BV70 Series with compression
fittings. The BVP80 and BVP70 Series are a
combination of the three key elements for long,
reliable, trouble free life–a premium quality ball valve,
a quality actuator designed to meet the torque
requirements of the valve, and a mounting system
which assures alignment and rigidity.

The BV80 and BV70 ball valves low operating torque
makes possible a compact actuator that is both
economical to install and operate. Precise
machining of all the valve components, including
the seats, controls the sealing preload. This assures
bubble-tight sealing, minimizes the operating torque
and optimizes the valve life.

The mounting system precisely couples the actuator
drive shaft to the valve stem. Additionally, the valve
stem nut is fixed within the actuator shaft. These
features combined with a rigid mounting bracket,
results in a pneumatically actuated ball valve which
minimizes backlash, assures optimum stem seal life
and eliminates any possibility of stem nut backing off
while in service.

The BVPS80 and BVPS70 Series offers a spring­return model requiring only 3.5 bar (50 psi) supply air
that can spring to open or close without loss of output
torque from the air operated side. This is achieved by
two opposing lightweight nylon resin or manufactured
aluminum housed spring modules that are fully
compressed by air operated diaphragm pistons.

All BVPS80 and BVPS70 Series are designed to
operate using an air supply of 3.5 to 8.6 bar (50 to
125 psi). The air can be delivered by direct mounting
pilot valves having NAMUR interfaces or from remote
pilot valves connected via means of
threaded orifices in the actuator face plates.

Caution: Care must be taken to assure that the
output torque of the BVP80 Series actuator selected
is adequate to turn the valve or device to be operated.

A Limit Switch accessory is offered for the pneumatic
actuators. The BVLS limit switch is easily mounted
to any pneumatic actuator and provides a means
to remotely display valve position or to interconnect
the valve with related equipment such as pumps
or other valves.

The limit switch accessory utilizes two mechanical
S.P.D.T. (Single-Pole, Double-Throw) micro switches
that respond to actuators’ fully open or fully closed
position by means of a cam fitted to the actuator top
shaft. The switches are rated at 10 amp 250 Vac max.

The limit switch is totally enclosed and may be used
in applications where a dust tight or weather tight
enclosure is required as well as in those locations
where general purpose enclosures will serve. The
housing, like our pneumatic actuators, is made from
6061-T6 aluminum and has a PTFE impregnated
hard-anodized surfaces to enhance corrosion
resistance.

The BVE80 and BVE70 Series electric actuated ball
valves are a compact mounting system that assures
rigid and precise coupling of the actuator to the valve.
The unique system features machined alignment
brackets oriented with precision locator elements that
serve to absorb the reaction torque independent of
the mounting bolts. The end result is a system that
eliminates the common problem of the mounting bolts
loosening while in service. Additional features include
thermal overload protection and manual override.

Power: 3.4 to 8.6 bar (50 to 125 psi) air. Sufficient air

delivery must be available at the actuator to ensure
dependable operation. The following precautions should be
observed: Air supply should be clean and free of moisture.
When dirty or wet air is a problem; a filter/separator should
be specified; these units are most effective when installed
as closely as possible to the actuator. A filter, when used,
should permit a minimum flow of 4 scfm at an upstream
pressure of 4 bar (60 psi). Eliminate severe restrictions to air
flow (certain solenoid valves and fittings). The most restricted
passage must have an area no smaller than 0.012 in
area of 3 mm (

⁄8") diameter orifice. If more than a single
actuator is to be supplied by an individual pilot, the minimum
passage requirement applies per actuator.
