The Series DCV/RDCV Dust Collection Valves are ideal for use with
the Series DCT1000 and Series DCT500 duct collection timer boards.
Both the Series DCV and RDCV 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 DCV has female
threaded connections. Both the “C” and “T” versions have a 90° angle between the inlet and outlet the most suitable configuration for pulse valve
applications. The design offers not only ease of installation, but also minimal airflow restriction for an exceptional cleaning pulse. The valves are
offered in both integrated and remote coil configurations.
