Yuken DT series Direct Type Relief ValvesYuken DT direct type relief valve photo and schematic

Adjusts maximum pressure and prevents damage caused by excess pressure in hydraulic circuits.

Model numbers:

Yuken BT series Pilot Operated Relief Valves

Used for relieving excessive pressure and protecting the hydraulic system, or for maintaining a constant pressure. Vent circuits allow remote control and unloading.

Yuken S-BG series Low Noise Type Pilot Operated Relief Valves

Pilot-operated, low-noise relief valves are used to keep the pressure controlled at steady levels in the hydraulic system. Used to protect pumps and control valves against excessive pressures. They can be controlled remotely. Unloading is accomplished using vent circuits.

Yuken BST series Solenoid Controlled Relief Valves

Combining a pilot operated relief valve with a solenoid operated directional valve eliminates extraneous piping due to the directly-mounted solenoid valve on the relief valve with a relief valve vent. Unloading the pump pressure can be accomplished with a remote electrical signal to the solenoid or through solenoid valve port pilot relief valves.

Yuken S-BSG series Low Noise Solenoid Controlled Relief Valves

By combining a low-noise pilot-operated relief valve and a solenoid operated directional valve, Yuken created a no-load pump. Operated by electric signals or when combined with a remote control relief valve, creates a two or three pressure control system for your hydraulics.

Yuken HT/HC Type Pressure Control Valves

Direct-operated pressure control valves are damped hydraulically and can be activated by pilot pressure (internal or external).

Yuken RT/RCT and RG/RCG series Pressure Reducing / Pressure Reducing & Check Valves

These valves function by setting the pressure of a hydraulic circuit below that of the main circuit. In addition, operation under remote control is possible by using the remote control port. Pressure reducing and check valves have check valves, which allow a free flow from the secondary side to the primary.

Model numbers:Yuken RC and RCT series pressure reducing / pressure reducing & check valves

Yuken RBG series Pressure Reducing & Relieving Valves

Designed for use in hydraulic balancing circuits, these valves provide pressure reducing and counterbalancing.

Yuken BUCG series Unloading Relief Valves

The high-efficiency valves are used to drive pumps efficiently, using minimum load and an can be used in high/low hydraulic circuits or in accumulator circuits. This unloading/relief valve includes an integrated check valve.

Yuken UBGR series Brake Valves

Brake valves create smooth stopping power by allowing braking with any level of pressure. Used in brake circuits of hydraulic motors and hydraulic cylinders.

Yuken Pressure Switches

These vibration-proof, semiconductor controlled pressure switches have a built-in electronic pressure sensor and a photocoupler insulated open collector output. This configuration places the movable parts away from the sensor for increased durability and reliability.

Yuken Hydraulic Pressure Monitoring Systems

For monitoring hydraulic system pressure.

Digital Pressure Monitors

Installed directly or remotely from the sensor, these monitors track hydraulic system pressure. If installed away from the sensor, it can be wire-connected, thereby minimizing hydraulic piping. The pressure sensor has no moving parts, offering reliability and durability.
