The Series DCV/RDCV Diaphragm Valves are ideal for use with the Series DCT1000
and Series DCT500 duct collection timer boards for controlling the air pulse in jet pulse
type dust collectors to clean the lters. 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 t 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 conguration for pulse valve applications. The design offers not
only ease of installation, but also minimal airow restriction for an exceptional cleaning
pulse. The valves are offered in both integrated and remote coil congurations.
FEATURES/BENEFITS
• Thermoplastic polyurethane diaphragm
for longer life
• High ow factor for effective cleaning
• Valve can be mounted in any position
• Quick on and off response time

The Mufer Accessory can be easily eld installed to any diaphragm valve with an exhaust.
Pneumatic exhaust ports are on the diaphragm valves that have dual diaphragms and the
units with the integral mounted solenoid. The mufer decreases the amount of noise when the
air is exhausted from the valve. Valves with dual diaphragms and an integral solenoid have two
exhaust ports and will require one A-237 and one A-238.
