KJL7F21B11PN Application Field and Working Principle

KJL7F21B11PN is a special electrohydraulic control valve developed and manufactured by the world-renowned industrial automation company, Parker-Hannifin Inc. The valve was designed to serve the industrial processes that require precise and reliable control of medium pressure and temperature in fluid lines.

The valve is designed as an electrohydraulic adjustable pressure relief valve for precise control of high-pressure fluid lines. The valve provides a relatively simple means of regulating the pressure of fluids despite the fact that the pressurizing force and the pressure relief balance of the system must constantly be maintained. The valve is designed with a single inlet and two outlets, and its utilization of an eddy current proportional valve offers proportional control in both directions.

The primary function of this particular valve is to provide a bypass for high-pressure fluids. It is typically used in order to maintain desired pressures and temperatures in systems such as hydraulic equipment, gas compressors, and molten metal. In such applications, an unsafely high pressure might otherwise build up in the system.

This particular valve achieves its pressure regulation by using the following working principle. For applications in which the pressure of the fluid is too high, the electrohydraulic control valve will reduce the amount of pressure in the system by bypassing the fluid through a bypass channel. This bypass channel connects to the outlet of the valve, from where the bypassed fluid enters into a separate chamber in the valve. This separate chamber is connected to the inlet of the valve, from which the bypassed fluid returns to the main body of the system.

To adjust the valve’s fluid pressure, a solenoid is used as an actuator. It will open and close the bypass channel according to the amount of pressure that is applied. This precisely regulated pressure can then be used to accurately control the pressure and temperature of the system. As a result, the valve can maintain a consistent pressure level, which is both crucial for efficient and safe operation of the machinery in question.

KJL7F21B11PN is a heavy-duty valve that can be easily integrated into virtually any industrial application simply by connecting it to the necessary control systems. The valve is designed to be reliable and durable enough to last several years of operation, even under large operating pressures. Its working principle and wide range of applications make it a great choice for industrial processes in need of precise control of pressure and temperature.
