The "LVSW-2 Series" is a double solenoid operated detent type two-way switching valve. It features a ball poppet type piston structure with "zero leak" technology and an axial thrust compensation structure, and its basic performance is the same as the "LVSH Series." Due to the detent mechanism, there is no need to keep the solenoid energized for long periods after opening, making it energy-efficient. 【Features】 ■ Combines a ball poppet type piston structure with "zero leak" technology and an axial thrust compensation structure ■ Basic performance is the same as the "LVSH Series" ■ Energy-efficient *For more details, please refer to the PDF document or feel free to contact us.

The "LVMH-2・HLM-2 Series" is a lever-operated spring offset type two-way valve that combines a "zero leak" technology ball poppet piston structure and an axial thrust compensation structure. The flow of hydraulic oil can come from either the A or B port, and there are two types: normally closed and normally open. In either type, "zero leak" ensures quiet and stable operation, and it is also highly durable. 【Features】 ■ Combines ball poppet piston structure and axial thrust compensation structure ■ Flow of hydraulic oil can come from either the A or B port ■ Achieves quiet and stable operation with "zero leak" ■ Highly durable *For more details, please refer to the PDF document or feel free to contact us.

This product is a "Zero Leak" electromagnetic pilot-type four-way switching valve developed by consolidating "zero leak" technology. It is a revolutionary product based on a ball poppet-type piston structure that is completely different from the spool type, possessing many advantages. There is no drain during operation, and the flow loss is zero, allowing for 100% effective use of the pump flow rate. 【Features】 ■ Low pressure loss and zero leakage from all ports when the valve is stopped ■ No drain during operation and zero flow loss ■ Adoption of a return poppet mechanism prevents shock to the actuator ■ Uses a compact and inexpensive small wet-type solenoid ■ No locking phenomenon even at a maximum operating pressure of 35 MPa, allowing for long-term holding *For more details, please refer to the PDF document or feel free to contact us.

The "LVSO-3 Series" is a composite valve that compactly integrates a solenoid-operated two-way switching valve, a check valve, a low-noise relief valve, and a throttle valve. It enables smooth and complete stopping of the self-weight descent operation of lifting devices and the like. Additionally, we also offer the "LVSO-1 Series" with pressure compensation. 【Features】 ■ Compact integration ■ Reliable operation ■ Quiet due to the adoption of a low-noise mechanism *For more details, please refer to the PDF document or feel free to contact us.

The "EM/EMV Series" is a valve that automatically closes the internal flow path due to the pressure difference generated by the flow velocity between the A and B ports when a sudden flow exceeding the set flow rate from the A port to the B port occurs due to a failure such as a pipe break on the B port line, instantly cutting off the flow of hydraulic oil from the A port. There are two types available: "EM," which only shuts off the installed piping, and "EMV," which is installed on multiple pipes and shuts off other pipes in conjunction when one of them operates. Additionally, we also offer the "EMS/EML/EMVL Series" with sensors. 【Features】 ■ Instantly cuts off the flow of hydraulic oil from the A port ■ Does not require electrical operation and operates reliably even during power outages *For more details, please refer to the PDF materials or feel free to contact us.

The hydraulic valve "Zero Leak Valve" is a hydraulic valve that can send 100% of the pump oil volume to the actuator due to its patented structure that completely shuts off the oil. It also features high durability, capable of withstanding 500,000 operational cycles. 【Features】 ■ Completely shuts off the oil to prevent leaks ■ No drain, allowing for the entire flow rate to be used without waste ■ By installing a sensor, the opening and closing status of the valve can be detected in real-time *For more details, please download the PDF or contact us.
