Pulse jet valves - threaded type

3/4" to 3" - with integrated magnet driven pilot valve or external pneumatically controlled

Pulse jet valve threaded type
VEM208
VEM214

Description

This series of pulse jet valves includes models with threaded connections from ¾ “to 2 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, from 2" with a double diaphragm and the 1½" version is also available in both versions.

The pulse jet valves differ in types with an integrated pilot valve or with external pneumatic control.

The special design ensures extremely fast opening, high flow and easy installation.

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.

Materials of the pulse jet valves - threaded type

The following table lists the materials of the individual valve components:

Cover Diecast aluminium (anodised)
Body Diecast aluminium (anodised)
Pilot base Aluminium (anodised)
Pilot Stainless steel
Diaphragm NBR (optionally Viton)
Bolts and screws Stainless steel
Diaphragm backing disk Stainless steel
Diaphragm spring Stainless steel

The different versions are divided into types with an integrated magnet driven pilot valve and with external pneumatic control. The following tables provide an overview of the standard valves with threaded connections.
