Definition:
pvd
dust bag shaker valves are designed for the systems that
discharges pressured air swift and produce air strokes as
shock. It operates in the same way with other 2 way solenoid
valves. But input and output connections are perpendicular
(90◦) to each other. So it sends air as stroke (shock) and
it is also called Air Shock (Jet Filter) valve.
Application Areas:
pvd
dust bag shaker valve area used in Cement, Ceramic, Drying,
Thermic Power Plants, Concrete Centrals, Detergent, Glass,
Iron & Steel, Chemistry and Food & Beverage sectors for
shaking accumulated dust and for protecting the bunkers
against dust sedimentation.
Application:
pvd
dust bag shaker valve can be mounted to system with coil or
without coil. It affects more than one dust bag (filter bag)
with the help of a collector. It can also be mounted on
filter directly.
pvd
dust bag shaker valve can be seperated into two parts, valve
body and coil that commands valve. This type of assembly
supplies the isolation of coil against water, dust and any
kind of corrosive fluids. Electrical connection is mounted
on a place far from valve body in this type of assembly.
Coils are settled in a aluminium command box and connect to
valves command input with an air tube.
pvd
dust bag shaker valves can be controlled by
pvd
timers. Timers can
be produced in a protective command box with 1...99 output.
Operating and waiting time of valve can be adjusted
according to the user by timer.
OPERATING PRINCIPLES
pvd
dust bag shaker valves have diaphragms. They can not execute
on-off operations if the line does not has enough
differential pressure like other solenoid valves with
diaphragm. Differential pressure, applied to input of valve,
shouuld be minimum 0.5 bar.
pvd
dust bag shaker valves are Normally Closed. They become "Open"
if they operate. Operation is completed by giving energy to
coil for 100-150 miliseconds. Waiting time can be adjusted
by administrator. Keeping operating time longer than 200
miliseconds does not have any advantage. Optimum and
economic operating time, 100-150 milisecods, reduce air
consumption.
