Rotary throttle valves are a excellent means to
control material flow while air gravity conveying. The rotary
throttle valve uses a rotary parabolic blade that allows for a low
profile design that delivers precise flow control. A 4-20mA
electric actuator is used to actuate the valve when real time
infinite positioning is required. If real time infinite
positioning is not required DCL uses a pneumatic actuator with a 3
position positioning package. The middle position can be
manually adjusted according to the customer's requirements. A large
variety of materials can be handled with rotary throttle valves
regardless of their abrasive nature or bulk density. The criteria
are particle size, moisture content, and temperature.
Material moisture content should be below 1% and
temperature can not exceed 1200 degrees Fahrenheit
[649° C].
DCL offers product compatibility tests in order to determine optimum
conveying angles and aeration
volumes. A minimum product amount of 2 cubic feet
[0.07 m³] is required
to conduct a proper test.
DCL offers a large selection of rotary throttle valves from
6 inches [152 mm] wide up to 36 inches
[914 mm] wide and conveying capacities up to
1000 cubic feet per minute [28.3 m³/min].
Rotary throttle valves are also available in a
high top or low top design allowing for maximum flow rate or minimum
head room depending on the application.
A choice of construction materials allow handling of all types of
products; fine, granular, lumpy, abrasive, corrosive, and sanitary
applications. A choice of electrical options are also
available allowing for installation in almost any environment; NEMA
4, NEMA 4X, NEMA 7, NEMA 9, 120V/220V control, 460V/415V power, etc. |
