Operation 2/2-way solenoid valves made of stainless steel - indirect

Pneuparts has a large selection of 2/2-way stainless steel solenoid valves for every application. These are electric valves with 2 ports (inlet and outlet) and 2 switching positions (open or closed).

The solenoid valves are usually normally closed (voltage = open), so that the valve will close in the event of a power failure. They can also be normally open (voltage = close) or bi-stable (electrical pulse = switch).

Solenoid valves are generally suitable for gases and non-viscous liquids and are very sensitive to dirt particles.

Indirectly controlled models always need a pressure differential to open, while (semi) directly controlled models can also switch without pressure. Indirect or servo-controlled solenoid valves use the differential pressure of the medium to open or close. The minimum pressure difference is usually 0.5 bar. Because the fluid pressure is used, a relatively small coil can still control a large membrane and therefore a high flow.

The most common gate sizes are from 1/8 "to 2", but there are also solutions outside this range.

Note: the internal parts of the solenoid valve are made of different materials (usually stainless steel 430F for the plunger). Medium-sized valves have an additional membrane to shield these parts from the fluid. A solenoid valve is often chosen because of its good sealing properties, the fast response time of usually tenths to hundreds of milliseconds, the durability, reliability and a wide range of options.

The stainless steel housing is suitable for compressed air, neutral gases, water, neutral light media, heating oil, other media on request.
