Black Aluminium Alloy Electronic Control Diaphragm Valve VNP208 DB18 Pulse Jet Valve

Features

The 200 series is a range of diaphragm valve suitable for dust collector applications, in particular for reverse pulse jet filter cleaning of filter bags, cartridges, envelope filter, ceramic filters and sintered metal fibre filters, The 200 series valve has the inlet port at 90° to the outlet port. The 200 series range comprises 7 models, from 3/4" to 3", all with threaded femal gas connections. The 1 1/2" model is available in the single ans double diaphragm versions, while the 2", 2 1/2" and 3" are all double diaphragm valves. The special design assures an extremely fast opening time, high flow rates and easy installations. The valves are constructed in die-cast aluminium and have an anodised pretection treatment which protect them from corrosive and environmental agents, Bolts and screws are in stainless steel. The 200 series is available in the following versions:
VNP, with integrated pilot
VEM, with remote pneumatic connection

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.
