What is a high -pressure solenoid valve?
High -pressure solenoid valve is a specialized valve type using solenoid activation and designed for effective high -pressure environment. As with most solenoid valves, a high -pressure solenoid valve is a linear jack, a piston valve. The only significant difference between these and other similar valve types is the design and materials used to make the valve chamber, valve and piston seats. These parts are usually more robust and are made from the degrees of materials most suitable for extreme pressures, temperatures and aggressive substances to which they are exposed.
solenoid valves are conventional piston or poppet valves that have a short draft, linear activation. The operation of the valve is achieved by electromagnetically integral solenoid. The solenoid finger is permanently connected to the valve stem and is equipped with a return spring. When the solenoid coil is under voltage, it forms a magnetic field that pulls the core to the core for hollow coils. This movement to be kindBy permission of the connection to the valve stem, the valve piston lifts the valve from the seat and opens the valve fluid flow, remains in this state until the power supply is cut to the solenoid and the return spring does not close the valve again.
High -pressure solenoid valve is an example of this type of valve designed specifically for high -pressure applications. These include medical devices, installations of devices and laboratories where gases and fluids such as oxygen, nitrogen and high -pressure chemical suspension are used. These applications require not only to withstand high pressures but also high temperatures and corrosive material. The design of the valves reflects the requirements placed on them with several fine deviations from conventional valve design.
externally, the high -pressure solenoid valve differs from its low -pressure peers. However, the internal mechanism usually differs significantly. Internal tolerances with which the valve is machined, they have tEndency to be much closer, with a significant increase in the strength of the mechanism as a whole. This includes the thickness of the material used to produce the piston, seats and stem, as well as an increase in the power spring force.
The valve case is also extended and made of materials that are able to withstand the aggressive nature of the operating environment, such as high -quality brass and stainless steel. The high -pressure solenoid valve pressures generally take place between £ 500 and £ 3,000 per square inch (3.447 and 20.684 megapascals). The valves are also available in one or multiple flow configurations.
