Pulse jet valves with flange connection
2" to 3 ½" - with integrated magnet driven pilot valve or external pneumatically controlled
Description
This series of pulse jet valves includes models with flange connections from 2" to 3 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 2" are available with a single diaphragm, from 3" with a double diaphragm and the 2½" version is also available in both versions.
The pulse jet valves differ in types with an integrated pilot valve or with external pneumatic control.
These valves create a venturi effect due to a larger inlet compared to the outlet. This results in a high flow rate at the outlet.
The inlet is provided with a square flange that can be coupled to a counter flange welded directly to the tank. The outlet is equipped with a quick connector, which allows a direct pipe mounting.
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.
