Rexroth HED8OP-2X/350
Versatile Hydraulic Control Switch
Product Description:
Rexroth HED8OP-2X/350 Versatile Hydraulic Control Switch 0.8 Kg Insulation Coordination Category 3
The hydro-electric pressure switch type HED 8 is a piston type pressure switch. It consists of a housing, an installation kit with piston, compression spring, adjustment element and a micro switch. When the pressure to be monitored is lower than the set pressure, the micro switch is operated. The pressure is imposed onto the piston through a nozzle, which is held by a spring plate. The movement of the piston is then transfered to the micro switch to either switch the electric circuit on or off, based on the circuit set-up. Meanwhile, the positive stop of the spring plate safeguards the micro switch from any succumb to mechanical destruction in case of a sudden pressure drop, while avoiding solid compression of the compression spring if an overpressure happens.
Notice: To further elongate the service life of this pressure switch, it should be installed with minimum vibration and secured against hydraulic pressure shocks.
The flange connection type of our product is according to the ISO 16873 standard. It also serves as a vertical stacking element in combination with sandwich plates, which is compliant with ISO 4401. In regards to pressure ratings, it comes in 5 varieties. Moreover, there are 4 adjustment types to choose from: spindle with/without protective cap, spindle with scale, with/without protective cap, rotary knob with scale and lockable rotary knob with scale. Customers will have the option of electrical connection through a large cubic connector or M12 x 1 connector. It also contains micro switch with NC/NO contact function that is capable of potential-free switching of currents ranging from 1mA to 2A. UL approval is available for pressure ranges up to 350 bar.

In the field of petroleum and chemical production, pressure relays can monitor pressure changes in containers and pipelines, timely trigger alarm devices or automatic control valves, and ensure the safety and stability of the production process. For example, when the pressure is too high, the relay can quickly open the safety valve to reduce the pressure. When the pressure is too low, it can promptly close the control valve to increase the pressure.
In the pharmaceutical field, pressure relays are responsible for real-time monitoring of the pressure of pharmaceutical equipment. Once abnormal pressure fluctuations occur, it can quickly take corresponding measures, such as closing valves, starting emergency pumps, etc., to prevent equipment damage and ensure drug quality.
In the field of food processing and packaging, pressure relays can monitor the pressure status of production equipment, ensuring that products are produced and packaged under suitable pressure conditions. This not only improves production efficiency, but also ensures that high-quality products are produced. Therefore, pressure relays play an important role in the production and packaging of products.
