The Features of Gas Magnetic Valve

The Gas Magnetic Valve (GMV) is a device which is based on magnetic field and enables the mechanical motion of gas.  This type of valve has been used in many applications.  Some of the common uses of a GMV include gas-powered clothes dryers, furnaces, and manufacturing facilities.

The device is designed to provide safety for users by preventing the ignition of combustible gases.  It complies with EN 161 and ROHS standards.  Moreover, it has passed the ISO9001 system certification.

A typical device contains three parts.  They are the control electrode, the excitation winding, and the excitation coil.  Each of these parts has its own function.  When an electrical current passes through it, the control electrode generates a magnetic field.  As a result, the valve disc moves along the rod.  If the electrical current is interrupted, the rod falls and the valve is closed.

There are two types of GMV.  One is normally closed and the other is open.  Both have different application.  The normally closed version is used in gas-fired heating equipments.  These valves can be either spool or poppet style.

For the purpose of safety, the valve is manufactured to meet the requirements of the European Union and its regulations.  Another advantage of these valves is their high reliability and long service life.

The main valve MC has an excitation coil and a control transistor Q2.  The first resistor R1 is connected between the excitation coil and the controller transistor.
