Valve Body: The valve body is the main component of the YUKEN A90 and is typically made of high-quality cast iron or steel.
It provides the structure and housing for all the internal parts of the valve.
Spool Assembly: The spool assembly consists of a cylindrical spool and a sleeve that moves within the valve body. It controls the flow direction and rate of the hydraulic fluid passing through the valve. The spool is precision-machined to ensure smooth operation and minimize leakage.
Actuator: The actuator is responsible for moving the spool within the valve body. It can be operated manually, electrically, or hydraulically, depending on the specific configuration of the valve. The YUKEN A90 offers various actuation options to suit different application requirements.
Ports: The valve has multiple ports for the inlet and outlet of hydraulic fluid. Commonly, it includes a P (pump) port for the hydraulic power input, T (tank) port for the fluid return, and A and B ports for connecting to hydraulic actuators. These ports are designed to accommodate specific thread sizes and connection types.
Pressure Rating: The YUKEN A90 valve is designed to operate under specific pressure conditions. It has a maximum pressure rating that determines the highest pressure it can withstand without causing damage or leakage. The pressure rating is typically expressed in pounds per square inch (psi) or bar.
Flow Rate: The valve has a specified flow rate that defines the maximum volume of hydraulic fluid it can handle per unit of time. It is usually expressed in gallons per minute (GPM) or liters per minute (LPM). The flow rate depends on the spool configuration and the size of the valve.
Operating Temperature Range: The YUKEN A90 is designed to operate within a specific temperature range. It can withstand high temperatures generated by hydraulic systems and is built to withstand the demanding conditions of industrial applications.
Seals and O-Rings: Sealing components such as seals and O-rings are essential parts of the YUKEN A90 valve.
They are used to prevent leakage of hydraulic fluid and ensure the proper functioning of the valve. These seals are made from durable materials, such as rubber or polyurethane, to withstand hydraulic pressures and maintain a reliable seal.
Mounting Options: The valve offers various mounting options to facilitate installation and integration into hydraulic systems. It can be mounted on a manifold block or directly on hydraulic equipment, depending on the specific application requirements.
Certifications: The YUKEN A90 may have certifications and approvals from relevant industry standards organizations to ensure its compliance with quality and safety regulations. These certifications provide assurance that the valve meets specific performance and reliability standards.
