We would like to introduce the "40Ω Series Proportional Electromagnetic Flow Control Valve" that we handle. The set flow rate changes continuously in proportion to the input current to the valve, allowing for remote control of the flow rate within the system by controlling the input current from the amplifier. Additionally, due to pressure and temperature compensation, the set flow rate is unaffected by changes in pressure (load) and temperature (operating oil viscosity). 【Features】 ■ Suitable for applications where the actuator needs to start, stop, or change speed without shock. ■ Used in combination with a dedicated power amplifier. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce our "Shockless Proportional Electromagnetic Direction and Flow Control Valve." This product inherits the basic concept of the variable shockless "G Series Electromagnetic Switching Valve," enabling speed setting at high speeds. With the maximum flow adjustment function, it allows for the adjustment of the actuator's top speed. Additionally, when combined with a dedicated power amplifier, it can control the speed, acceleration, and direction of the actuator with a single valve, simplifying the hydraulic circuit and reducing costs. 【Features】 ■ Speed setting at high speeds is possible ■ Control of the actuator's speed, acceleration, and direction can be done with a single valve ■ Simplification of the hydraulic circuit and cost reduction are achievable *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Proportional Electromagnetic Power Saving Valve." This product is an energy-saving valve that supplies the minimum required pressure and flow rate needed to drive the actuator. The high-flow series doubles the maximum flow rate, allowing for a reduction in valve size by one rank compared to conventional models, contributing to the compactness of the equipment. 【Features】 ■ Doubles the maximum flow rate ■ Enables compact equipment design *For more details, please refer to the PDF materials or feel free to contact us.
