Automated
On/Off and
Modulating Control
Valves.
Automated valves can be operated
with electric, pneumatic, electro-pneumatic,
and electro-hydraulic powered
actuators. Actuators allow valves
to be operated automatically
by a control system or manually
from a remote location. Valve
automation brings significant
advantages to a plant in the
areas of process quality, efficiency,
safety, and productivity. Click

Angle Valves
Angle-Seat Valves are operated
with a piston actuator. These
compact pneumatic valves are
ideal for on-off valve applications
and an excellent alternative
to more expensive automated
valves. High flow rates are
obtained with the streamlined
flow path. These reliable, low
maintenance valves can be fitted
with a comprehensive range of
accessories for positioning,
indication, and manual override.
Ball Valves
Ball valves are reliable and
simple to use as a shutoff valve
or flow metering valve. Just
a quarter turn of the handle
opens or closes the valve. Handle
position lets you "see"
the valve's position.

Butterfly Valves
Butterfly valves are used where
economical, high capacity valves
are needed. Resilient liners
provide bubble tight shutoff
in general service applications.
High-performance butterfly valves
provide excellent flow control,
and Triple offset metal seated
butterfly valves are designed
for high pressure and high temperature
severe service. Butterfly

Control Valves
Control valves modulate the
flow of fluids in flow, pressure,
level, and temperature control
systems. They consist of three
main parts: a valve body, actuator,
and positioner. The positioned,
through the actuator, drives
the valve in proportion to a
control signal. Various types
of valve and actuator combinations
are available to suit most process
control applications.
Diaphragm Valves
Diaphragm valves have excellent
shut-off and flow control characteristics.
A flexible molded diaphragm
regulates flow, provides tight
shutoff, and isolates the fluid
from the environment. The valve
consists of the body, diaphragm,
and hand wheel assembly. Their
simple design and wide choice
of materials make them ideal
for corrosive, abrasive, and
sanitary services.
Float Valves
Float valves automatically control
liquid level and prevent overfilling
tanks. The valve is operated
mechanically by a float which
rests on top of the liquid.
As the liquid level rises, it
pushes the float up and closes
the valve. As the level falls,
the valve opens. The amount
of liquid pressure the valve
can shutoff against is determined
by the length of the rod and
size of the float.
Gate Valves
Gate valves have a sliding wedge
or disc which reciprocates into
and out of the valve port. These
valves are ideal for isolation
of general purpose as well as
high pressure and high temperature
applications where operation
is infrequent. Manual operation
is accomplished through a multi-turn
handwheel assembly.
Plug Valves
Plug valves are similar to ball
valves except instead of a spherical
element, a cylindrical element
is used as the internal restriction.
Plug valves are typically more
expensive than ball valves,
but they are inherently more
rugged as well. The plug is
guided by a sleeve which acts
as the sealing member. These
valves are available in 2, 3,
and 4-way configurations.
Solenoid Valves
Solenoid Valves are simple electrically
operated devices. The valve
plug is held in place by a spring.
When electric power is applied
to the solenoid (Energized),
the current draw through the
coil generates an electromagnetic
force which opposes the spring,
causing the plug to change position.
When power is taken away (De-energized),
the spring returns the plug
to the normal position.
