PRODUCT DETAILS

Madagas Gas Solenoid Valve

MVD/5

Technical Description

The MVD/5 series safety solenoid valves are single-stage automatic shut-off valves that meet the requirements of EN 161 for gas burners and gas equipment.

- Max. operating pressure up to 200, 360 or 500 mbar (20, 36 or 50 kPa)

- MVD: fast opening

- Main volume adjustable(MVD/MVDLE)

Gas solenoid valves at home and abroad are divided into three categories in principle

One, direct acting gas solenoid valve: electromagnetic coil electromagnetic force to close the piece from the seat, gas solenoid valve working principle: when energized.Valve open;Power, electromagnetic force dissipation, the spring to close the pressure on the seat, the valve closed.But the diameter is generally not more than 25mm solenoid valve features: vacuum, negative pressure, zero pressure can work normally.

Two, spread the direct acting gas solenoid valve: when there is no pressure difference between the inlet and the inlet, the working principle of the gas solenoid valve: a direct acting and pilot type combined principle.After the power, the electromagnetic force directly to the pilot valve and the main valve closed parts in turn up, the valve opened.When the inlet and outlet to start the differential pressure, after the power, the electromagnetic force pilot valve, the main valve chamber pressure rise, the pressure falls on the chamber, so as to use the differential pressure to push the main valve upward;Power, the pilot valve using spring force or medium pressure to push the sealing parts, moving down, so that the valve closed.But the power is larger, solenoid valve features: zero pressure difference or vacuum, high pressure can also be * action.Request required horizontal device.

Three, pilot gas solenoid valve: gas solenoid valve to open the pilot hole, gas solenoid valve working principle: when energized.The pressure of the upper chamber drops rapidly, and the pressure difference of the upper, lower and higher is formed around the sealing part. The fluid pressure pushes the sealing part upward, and the valve opens;Power, the spring force to the pilot hole closed, the inlet pressure through the bypass hole agile chamber in the close valve around the formation of low and high pressure difference, fluid pressure to push the closed parts move down, close the valve. Can be installed at will (to be customized) but must meet fluid differential pressure conditions.

MVD/5

Madagas Gas Solenoid Valve, normally when closed, fast opening, fast closing, manual limitation of flowing gas volume by adjusting main volume.
