Pulse jet valves - Dresser nut type for direct pipe mount
for direct pipe mount 1/2" to 1 1/2" - with integrated magnet driven pilot valve or external pneumatically controlled
Description
This series of pulse jet valves includes models with dresser nut connections for direct pipe mount from ¾" to 1 ½". These valves are particular used for reverse pulse-jet filter cleaning of filter bags, cartridges, envelope filters, ceramic filters and sintered metal fibre filters.
They have an inlet port at 90° to the outlet port.
Models up to 1" are available with a single diaphragm, the 1 ½" version with a double diaphragm.
The pulse jet valves differ in types with an integrated pilot valve or with external pneumatic control.
Optionally, we also offer versions with ATEX certified pilot valves.
A well thought-out structure and a fast delivery time for spare parts such as diaphragms, springs and coils enable simple maintenances.
