The heart of the filter valve is the TPE diaphragm
The TPE diaphragm is the key component in any filter valve de-
signed to provide short pressure decay times and high kv-values.
Service life is 4-5 times longer than that of comparable, conven-
tional fabric diaphragms. Our product filter systems eliminate the
danger that rubber particles could enter the product. The TPE
material used has FDA approval (Food and Drug Administration,USA)
Temperature range - fluid temperature
Standard diaphragm: –40 °C to 85 °C
For higher temperatures: –10 °C to 140 °C

1 . The design with integral compression fittings will facilitate
installation because there is no need for threaded piping
2 . The high quality diaphragms are reinforced and wear resistant
to guarantee a long operating life, even under harsh conditions
3 . Integral pilot operated valves satisfy all relevant EC
directives
4 . The pulse diaphragm valves are especially designed for dust
collector service applications, combining high flow, long life and
extremely fast opening and closing to produce reliable and
economical operation.
5 . The high flow, angle type bodies in combination with the
special main diaphragm assemblies give the unique operating
features required for dust collector service applications
Handling
The solenoid system with unique bayonet connection is easily
mounted - just push down and turn. Its internal components are
captive. The high specification plastic enca- sed solenoid can be
inserted in 3 different positions 120° apart. Standard IP 65.
Sound of silence
The silencer reduces noise emission and prevents foreign matter
getting into the valve.
Connection
BSP or NPT female thread to interational standards. Compression
Fitting.
Response
The volume over the diaphragm is mini- mised for extremely fast
opening with ideal peak pressures. In conjunction with the high
flow rate this achieves very effective cleaning. The similary
optimised closing time ensures low air consumption.
Reliability
All of the dynamically loaded valve elements are designed to last.
The solenoid design of the pilot offers maximum security against
icing.

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.
