US NELSON N800-DN100 series solenoid valve

Nielsen 800 Series Control Valve

The American Nielsen Solenoid Valve 800 series has exceptional quality. The valve body has a smooth surface and fine workmanship, and is made of high quality materials.

Among the many demanding applications, Nielsen Solenoid Valves are fully reflected in their superior quality and reliable operation. The Nielsen 800 Series Control Valve is a multi-function diaphragm control valve. The base valve body can be configured with different control units to achieve different control combinations. Can be applied to pressure control, flow control.

Performance characteristics of the US Nielsen solenoid valve 800 series:

1. Under the condition of lower pressure, the whole system can be started to save energy.

2, has a high flow, and the pressure loss is small.

3. Excellent pressure regulation function.

4, compact structure, can simplify transportation, installation and maintenance.

5. It is equipped with special natural rubber diaphragm sleeve, which is resistant to high pressure or common irrigation chemicals; and can be closed without leakage.

6. It is composed of anti-corrosion steel, brass, coated aluminum and other super-abrasive materials, and the pressure regulating shaft is hard chrome.

7. The special design of the minimum water opening valve reduces the blockage of the coil and regulator.

8, self-cleaning built-in filter.

9, with high-quality fast connection pipe fittings.

10. An external filter can be selected for special antifreeze design.

The working principle of the American Nielsen solenoid valve:

The closing and opening of the solenoid valve is achieved by the pressure from the line acting on the reinforced rubber diaphragm. When the pressure medium (water, etc.) enters the valve control valve, the diaphragm is pressed down to close the valve passage. When the control chamber pressure is discharged to the atmosphere or downstream of the pipeline, the diaphragm rises and the valve passage is opened.

Since the valve does not have a valve stem, a gasket, an orientation seat, etc., the only movement in the passage is the diaphragm, so there is no rust and lock, and it has higher stability. Use electric heating and other heating measures to ensure that the water in the valve will not freeze (except the valve body, especially to ensure that the commａnd tube does not freeze).
