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.
Installation
For your safety do not pressurise system until all valves and pipes
are fully
secured. Do not attempt to remove a fitted valve while system is
under pressure.
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, tighten
dresser nuts.
5. Tanks and pipes must be independently restrained from valve.
6. Make electrical connections to solenoid or connect RCA pilot
port to pilot valve
(RCA valves only).
7. Apply moderate pressure to system and check for installation
leaks.
8. Fully pressurise system.
9. Test fire and listen for proper actuation and crisp pulse noise.
Valve is not a structural component. Do not rely on valve to retain
tanks or pipe.

Introduction
Electromagnetic pulse valve refers to the gas through the valve in
instantaneous once a electrical signal received. Just like pulse
phenomena, it has the change of the short fluctuation. Therefore it
is calls the pulse valve. The Industry standard definition of
electromagnetic pulse valve for electromagnetic pilot valve and
pulse valve together, diaphragm valve controlled by electrical
signals.
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.
