Find the right High Pressure Solenoid Valve for the job

  •   High-Pressure Solenoid Valve is used in a variety of industries, from global oil production (about 13% of which is produced in the United States) to aerospace manufacturing. In fact, they are present in almost every hydraulic system and are used to safely keep the system pressure below the required upper limit. Generally speaking, there are five different types of High-Pressure Solenoid Valve; let's take a look at each of them.

      Pressure relief: The fluid power system operates within a preset pressure range. This range is a function of the forces that the system must generate to accomplish the required work; if these forces are not controlled or restricted, they can damage (and sometimes extremely expensive) equipment and fluid power components. The pressure relief valve acts as a protective measure to limit the maximum pressure by transferring excess oil when the pressure is too high.

      Reduction: The reduction valve is the most practical component when it comes to maintaining a secondary, lower pressure in the hydraulic system. They are the only High Pressure Solenoid Valves on this list that remain open and closed when subjected to sufficient downstream pressure. There are two types of High Pressure Solenoid Valve: direct-acting and pilot-operated.

      Sequence: Some circuits have multiple actuators, so these actuators (such as cylinders) need to be driven in a specific order or sequence. Limit switches, timers and other electrical control equipment are used for this purpose.

      Balance: These High Pressure Solenoid Valves are mainly used to set pressure in a part of the circuit, and are usually used to balance weight or external forces. The main oil port of the valve is connected to the rod end of the cylinder, and the pressure setting is slightly higher than the pressure required to prevent the load from falling freely.

      Unloading: As expected, the unloading valve is used to unload the pump. Once the system pressure is reached, they direct the output flow of the pump (usually the output of one pump in a multi-pump system) directly to the storage tank at low pressure. When the force applied by the external pilot signal acting on the other end of the spool is sufficient to exceed the force applied by the spring, the spool moves and transfers the effluent of the pump to the tank.

      Finding the right High Pressure Solenoid Valve for the job—whether you need a ball valve or a gate valve—is essential in high-pressure situations.
