This catalog introduces the "pressure control valves" that we handle. It includes the "pilot relief valve," which is used as a pilot valve, as well as the "direct-acting relief valve," which is used for maximum pressure adjustment in low flow circuits and as a safety valve. Additionally, we also introduce the "pilot-operated relief valve" and the "low-noise relief valve." We encourage you to read through it. 【Featured Products (Partial)】 ■ Pilot Relief Valve ■ Direct-Acting Relief Valve ■ Pilot-Operated Relief Valve ■ Low-Noise Relief Valve ■ Relief Valve (High Pressure Type) *For more details, please refer to the PDF document or feel free to contact us.

The "B3G Series" is a pressure control valve that allows for remote control and unloading through a vent circuit. It is developed to adjust pressure up to a high pressure of 35 MPa, and is used to protect pump control valves from excessive pressure while simultaneously maintaining a constant pressure in the hydraulic system. Please feel free to contact us when you need assistance. 【Specifications (Excerpt)】 <B3G-03> ■ Maximum operating pressure MPa: 35 ■ Pressure adjustment range MPa: up to 35 ■ Maximum flow rate L/min: 250 ■ Weight kg: 4.1 *For more details, please refer to the PDF document or feel free to contact us.

The "B3SG series" is a pressure control valve that can be adjusted to a maximum pressure range of 35 MPa. It integrates a relief valve and an electromagnetic switching valve, and is used to operate the pump under no-load conditions via an electrical signal, or in conjunction with a pilot relief valve to control the hydraulic system with two or three pressure levels. Please feel free to contact us when you need assistance. 【Specifications (excerpt)】 <B3SG−03> ■ Maximum operating pressure MPa: 35 ■ Pressure adjustment range MPa: up to 35 ■ Maximum flow rate L/min: 250 *For more details, please refer to the PDF document or feel free to contact us.

The "H/HC Series" is a direct-acting pressure control valve with hydraulic cushioning that can be operated by internal or external pilot pressure. The "H Type Pressure Control Valve" can be used as a sequence valve, unload valve, or low-pressure relief valve depending on the configuration of the valve. Additionally, the "HC Type Pressure Control Valve" is a direct-acting pressure control valve that incorporates a check valve, allowing free flow from the secondary side to the primary side. 【Specifications (Excerpt)】 <HT/HG−03> ■ Maximum Operating Pressure MPa: 21 ■ Maximum Flow Rate L/min: 50 ■ Weight kg ・H/HC Type: 3.7 ・HG/HCG Type: 4.0 *For more details, please refer to the PDF document or feel free to contact us.
