The "LVSW-2 Series" is a double solenoid operated detent type bidirectional 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 that of the "LVSH Series." Due to the detent mechanism, there is no need to keep the solenoid energized for long periods after opening, which saves energy. 【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-saving *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 features 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 available: normally closed and normally open. Both types provide quiet and stable operation with "zero leak" performance and are highly durable. 【Features】 ■ Combines ball poppet piston structure and axial thrust compensation structure ■ Flow of hydraulic oil can come from either 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 integrating "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, resulting in 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 more. 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 materials 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 occurring 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 breakage on the B port line. This valve instantaneously cuts off the flow of hydraulic oil from the A port. There are two types available: "EM," which shuts off only 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 ■No electrical operation is required, ensuring reliable operation 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 boasts high durability, capable of withstanding 500,000 cycles of operation. 【Features】 ■ Completely shuts off oil to prevent leaks ■ No drain, allowing for the full usage of the flow rate without waste ■ By installing a sensor, the valve's open and close status can be detected in real-time *For more details, please download the PDF or contact us.
