Aluminium RCA15T Pulse Jet Solenoid Valve For Dust Collector

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.

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.

 

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.

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.
