Solenoid Pulse Valve

A Solenoid Pulse Valve(also referred to as an Electromagnetic Pulse Valve or Diaphragm Pulse Valve)is a specialized electromechanical control valve designed to deliver instantaneous,high-velocity bursts of compressed air.It acts as a precise"air switch"for industrial systems,primarily serving as the core component in the pulse-jet cleaning system of baghouse dust collectors.

Working Principle

The valve operates on a pilot-controlled diaphragm mechanism,utilizing pressure differentials for rapid actuation:

Closed State(De-energized):The solenoid coil is inactive.The pilot hole is sealed,and pressure equalizes across the diaphragm,keeping it firmly closed against the valve seat.

Opening(Pulse Signal):A brief electrical pulse energizes the solenoid,lifting the armature to open the pilot hole.This rapidly vents the pressure chamber above the diaphragm.

Pulse Blowing:The sudden pressure difference forces the diaphragm to snap open,releasing a powerful,short-duration pulse of compressed air.

Closing(Reset):When the pulse ends,the solenoid de-energizes.The armature resets,the pressure chamber recharges,and the diaphragm closes instantly.

Key Features

Ultra-Fast Response:Completes an open/close cycle in milliseconds,ideal for high-frequency operation.

High Flow&Powerful Blasts:Delivers concentrated,high-impact air pulses for efficient filter cleaning.

Low Power Consumption:Designed for intermittent,pulse-duty operation,not continuous use.

Durable Construction:Typically features an aluminum alloy body and a high-performance rubber diaphragm for longevity.

Versatile Voltages:Available in common industrial voltages(e.g.,AC220V,AC110V,DC24V).

Main Types

Right-Angle Type:The most common,with inlet and outlet at 90 degrees,suitable for standard installations.

Submerged Type:The inlet is submerged directly within the compressed air tank(air bag),offering lower pressure loss and stronger pulses.

Straight-Through Type:Features inline(180-degree)ports for specific pipeline configurations.
