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.

PERATION
O
eries DCV includes an integral solenoid and Series RDCV needs to be used with
S
remote pilot solenoid valve. Both are normally closed valves. When the remote
a
ilot solenoid valve or integral solenoid opens, pressure is released (exhausted)
p
from the top of the diaphragm in the pulse valve. This allows the line pressure on
the bottom of the diaphragm to push the diaphragm up and open the main orifice
of the pulse valve. When the solenoid then closes the pressure on the bottom and
he top of the diaphragm equalize closing the main orifice of the pulse valve.
t
NSTALLATION
I
OCATION
L
elect a location that will not exceed the ambient temperature specifications of the
S
valve. The system must be located in an enclosure that meets relevant safety
standards and electrical codes of the environment.
MOUNTING
he DCV/RDCV can be mounted in any position. For optimum life and performance
T
t is recommended that the unit be mounted vertically and upright to reduce the
i
hance of foreign matter accumulating in the valve. For DCV in weatherproof
c
applications it is recommended that the cable gland be positioned face down to
avoid possible rainfall or water from entry.
PROCESS CONNECTIONS
or DCV/RDCV with coupling connections:
F
. Connect piping so that pneumatic input is the bottom connection and the outlet
1
s the side connection at 90°.
i
2. Stub pipe (blow tube) must be free of burrs, rust, oil, and other debris.
3. Disassemble compression fittings and place the retaining nut, retainer, and gas
ket onto the piping. Make sure that the beveled edge of the gasket faces the
valve body.
4. Connect fittings to the valve body. Make sure that the pipe is inline with the valve
ports. Nut and seals are for connection only and should not be used for support
purposes.
arning: Before installation make sure all air pressure has been
W
released, electric power has been turned off, and air pressure source
has been closed. Turn power on and increase pressure only after
installation is complete.

4. Connect wires to proper terminals on the terminal block.
5. Snap terminal block back into the cover. The connector cover may be rotated in
90° increments to position the cable entry as needed for the application.
einstall the center screw and screw back into the solenoid body.

Warning: To prevent the possibility of death, serious injury or property damage, turn
off electrical power, depressurize system and unit, and vent fluid to a safe area
before servicing.
The DCV/RDCV should be cleaned periodically. The amount of time between
leanings depends on the application. Preventive Maintenance includes keeping
c
edia clean of material and oil free, and periodic testing to ensure proper operation
m
nd to look for wear or damage. Replacement diaphragm assemblies are available
a
from the factory.
Notes:
• Make sure pipes are anchored securely to avoid separation from the valve.
• Do not use the valve for leverage when connecting piping.
• Do not over-tighten retaining nut or valve damage may result. Tighten retaining
nuts just sufficiently for sealing to prevent leakage. This is a gasket seal and does
not require excessive turning of the nut.
For DCV/RDCV with NPT connections:
1. Connect piping so that pneumatic input is the bottom connection and the outlet
is the side connection at 90°.
2. Stub pipe (blow tube) must be free of burrs, rust, oil, and other debris.
3. Thread piping into the valve body. Make sure that the pipe is inline with the valve
ports. If using tape or pipe compound, apply to the male piping threads and use
sparingly as it may come loose and affect valve operation. Do not apply tape or
pipe compound directly to the female valve body threads.
Notes:
• Make sure pipes are anchored securely.
• Do not use the valve for leverage when connecting piping.
Pressure Connection from Remote Pilot Solenoid Valve
(For RDCV units)
The RSV, remote pilot solenoid valve, should be mounted as close as possible to
the RDCV pulse valve. The maximum distance is 9.8 ft (3 m). Tubing from the
remote solenoid valve is connected to the exhaust port on the top of the RDCV
pulse valve. If using tape or pipe compound, apply to the male piping threads and
use sparingly as it may come loose and affect valve operation. Do not apply tape
or pipe compound directly to the female valve body threads.
