The "SPL1 type" is a lead switch type oil level relay used for monitoring the unloading valve oil level adjustment device of the pressurized oil system, monitoring the outflow of oil from the collection tank and pressurized oil tank, and for controlling the opening and closing of the oil level adjustment valve in conjunction with an electric unloading valve. The fluid used is compatible with turbine oil (VG#46). The oil level detection range is within L = 1000 mm. 【Components】 ■ Float type level switch: 1 set (contact 2a to 4a available) ■ Baffle tube: 1 set ■ Drain valve (20K・10A): 1 unit (mounted at the bottom of the baffle tube) *For more details, please refer to the PDF document or feel free to contact us.

The "SASP type" is a pressure oil automatic stop valve that boasts a maximum operating pressure of 2.94 MPa (30 kgf/cm²). This product is generally controlled by the solenoid valve "20Q" and serves as the final control valve for pressure oil. It is manufactured with an automatic handle-less indicator, and the standard structure is an angle type. Additionally, it is possible to manufacture a version without an indicator with a handle as an option. 【Main Specifications】 ■ Maximum Operating Pressure: 2.94 MPa (30 kgf/cm²) ■ Diameter: 25A to 100A ■ Model: SASP type, handle-less with indicator (angle type) ■ Coating Color: Please specify using Munsell notation ■ Options: Versions without an indicator with a handle can also be manufactured *For more details, please refer to the PDF document or feel free to contact us.

The "SPL2 type" is a magnetostrictive pressure tank oil level relay developed for monitoring the unloading valve oil level adjustment device of a hydraulic oil system, monitoring the outflow of oil from collection tanks and pressure tanks, and for controlling the opening and closing of the oil level adjustment valve in conjunction with an electric unloading valve. The fluid used is compatible with turbine oil. The contact output is relay output DC30V 5A (DC110V 1.5A). 【Components】 ■ Magnetostrictive level sensor: 1 set (output 4–20mA) ■ Display box: 1 unit (mounted on the top of the wave pipe) ■ Wave pipe and valves: 1 set (existing parts can be reused, but diameter needs to be considered) *For more details, please refer to the PDF document or feel free to contact us.

• relay

The "SPL3 type" is a magnetostrictive oil level relay developed for monitoring the regular oil level in oil collection tanks and lubrication oil tanks, as well as for monitoring abnormal oil levels due to oil leakage from these tanks and contamination by cooling water. A display box is mounted on the upper part of the sensor, which uses a float-type magnetostrictive sensor with an accuracy of ±1mm. The movement of the float is converted to a 4-20mA signal, and alarm contact output is provided via a digital panel meter. Additionally, after pressing the data measurement button during inspections and completing other tasks, the maximum and minimum oil levels during that time can be measured using the digital panel meter display switch. 【Components】 ■ Float sensor: 1 set (output 4-20mA) ■ Display box: 1 unit (mounted on the upper part of the sensor) ■ Bypass pipe: 1 set (optional item / can be reused from existing equipment / however, diameter needs to be considered) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Electric Unloader Conversion." The mechanical unloader pilot valve directly draws hydraulic pressure from the pressure oil tank and switches between unloading and loading based on the balance with the spring. However, after years of use, the spring may wear out, and mechanical misalignments can cause fluctuations in pressure width and pressure range. This technology allows for easy individual adjustment of both pressure width and pressure range using a pressure relay. Additionally, it offers stability in operational width and range, and is highly durable. 【Features】 ■ Pressure adjustment can be easily made individually for both pressure width and pressure range using a pressure relay. ■ The pressure relay is durable, capable of over 10 million uses. ■ The pressure relay can be easily checked for operation from the outside. ■ In the event of a power loss, the solenoid valve turns off and maintains the "loading" state. *For more details, please refer to the PDF document or feel free to contact us.

Our company has developed a robust and reliable rectangular armored pressure oil level gauge (SOL type) because the traditionally used glass tube oil level gauges are weak against shocks and pose safety concerns. The sealing part uses an O-ring system to prevent oil and air leaks. Additionally, the mounting dimensions for the valve center (between surfaces) of the oil level gauge can be finely adjusted. Please feel free to contact us if you have any requests. *For more details, please download the PDF or contact us.
