Series DCS/RDCS Springless Diaphragm Valves
Specifications - Installation and Operating Instructions
DCS35T1D
DCS35C1D
The Series DCS/RDCS Springless Dust Collection Valves are ideal
for use with the Series DCT1000 and Series DCT500 duct collection
timer boards. A springless design offers not only durability, but also
reliability for an exceptional cleaning pulse. Both the Series DCS and
RDCS have the option for either coupling or NPT connections. The
coupling connection allows for a quick and simple installation. Only the
stub pipe and blowtube need to be cleaned and deburred before the
valve is fit into position. The “T” Series DCS has female threaded
connections and the “C” Series DCS has a coupling connection. Both the
“T” and “C” versions have a 90° angle between the inlet and outlet: the
most suitable configuration for pulse valve applications. The valves are
offered in both integrated and remote coil configurations.
