RCA62T High performance diaphragm valve G2 1/2" pulse dust
collector
Description
High performance diaphragm valve with threaded ports. Available
with integral pilot or as remotely piloted valve. Outlet at 90° to
inlet.
Suitable for
Dust collector applications, in particular for reverse pulse jet
filter cleaning including bag filters, cartridge filters, envelope
filters, ceramic filters, and sintered metal fibre filters.
Construction
Body: Aluminium (diecast)
Ferrule: 304 SS
Armature: 430FR SS
Seals: Nitrile or fluororubber (reinforced)
Spring: 304 SS
Screws: 302 SS
Diaphragm Seat: PA-6 (standard), fluororubber coated mild steel or
High Density PE Refer to Q Series Solenoid product data sheet for
solenoid construction details.
Operation
Recommended on time range: 50-500ms
Recommended time between pulses: 1 minute or greater
Maintenance
Before conducting any maintenance activity on the system ensure
that components are fully isolated from pressure and power
supplies. Pressure and power should not be reapplied until the
valve has been fully assembled. Diaphragm and pilot inspection
should be conducted annually.
Approvals
Integrally piloted valves meet the requirements of:
. Atex II 2D Mechanical
. CSA (C&US)
C22.2 No. 139-1982 UL Std No. 429
. C-Tick - integral pilots
. EMC (89/336/CE) - integral pilots
Installation
1. Prepare supply and blowtube pipes to suit valve specification.
Avoid installing valves underneath the tank.
2. Ensure tank and pipes are free from dirt, rust or other
particulate.
3. Ensure supply air is clean and dry.
4. Mount valves to inlet pipes and blowtube to valves, ensuring no
excess thread sealant can enter the valve itself.
5. Make electrical connections to solenoid or connect RCA pilot
port to pilot valve (RCA valves only).
6. Apply moderate pressure to system and check for installation
leaks.
7. Fully pressurise system.
8. Test fire and listen for proper actuation and crisp pulse noise.

Working principle
Electrical pulse controller send input signals so that the
electromagnetic armature attracts the moving bar. Unclose the
balancing hole to release the pressure gas in the back cavity of
diaphragm quickly; the pressure gas in the front cavity holds up
the diaphragm to open the passage and the valve starts cleaning.
The pulse signal disappears and the spring of the armature works
immediately to resume the moving bar so as to close the balancing
hole. The pressure gas in the back cavity of the diaphragm and the
spring work together to close the passage the valve stops cleaning.
The damping hole in the diaphragm functions to damp the airflow
when the moving bar of armature holds up for balancing and to
transit the air to the back cavity as soon as the balancing hole is
shut to close the passage and stop cleaning.
