Curved blade valves are designed to cut off product
flow from outlets of storage bins, silos, conveyors, gravity flow
chutes and other discharge points handling dry bulk materials.
The curved blade valves are fast acting, tight sealing, and very
effective for regulating flow rates. The curved blade valve
should only be used when handling fine or granular materials and not
materials containing a large percentage of lumps. The housing
on larger sizes is
constructed of plate steel with cross member supports. The reinforced curved blade pivots on two flanged
bearings allowing it to open and close with ease. Actuation of
curved blade valves can be accomplished in many ways; pneumatically
for fast action, hydraulically for power, electrically for precise
positioning, and manually with a chain wheel or lever. The
seals are designed to eliminate product leakage when the blade is in
the shut off position. The seals are mounted to the housing
instead of the blade allowing for easy access and replacement.
Blade seals are selected according to the material being handled and
are available to suit any application.
DCL offers a large selection of slide gate valves from
6 inches [152 mm] square up to 36 inches
[914 mm] square. Slide gates are also available in
sizes larger than 36 inches [914 mm] and
in special configurations including hardened liners.
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.
