Product Description

Product Overview

The S-BSG-03/06/10-2B3A/3C2-A240-N1-51, S-BSG-06-2B2B-A240-R-52, S-BSG-06-V-2B2B-A240-52 and S-BSG-06 belong to the Yuken S-BSG series of low-noise solenoid controlled relief valves. These valves combine a low-noise pilot-operated relief valve with a solenoid directional valve, significantly reducing operating noise while retaining remote unloading and multi-pressure control functions. Fully interchangeable with original Yuken S-BSG units, every valve undergoes 100% simulated operating-condition testing for quiet and reliable performance in noise-sensitive hydraulic systems.

Technical Specifications 

  • Model: S-BSG-06-2B2B-A240 / S-BSG-03 / S-BSG-10 etc. (S-BSG low-noise series)
  • Type: Low-noise solenoid controlled relief valve (low-noise pilot relief + solenoid directional valve)
  • Maximum operating pressure: 25 MPa
  • Maximum flow: Size 03 approx. 100 L/min; Size 06 approx. 200 L/min; Size 10 approx. 400 L/min
  • Pressure adjustment range: up to 25 MPa
  • Connection: Sub-plate mounting
  • Solenoid voltage: common A240 (AC 240 V), D24 etc.
  • Vent types: 2B3A, 2B2B, 3C2 etc.
  • Optional features: High venting pressure (V), Vent restrictor (A)
  • Weight: approx. 5.7–13.1 kg (depending on size and solenoid configuration)
  • Hydraulic fluid: Petroleum-based

Key Technical Advantages

  1. Low-noise pilot design: Dedicated low-noise pilot-operated relief structure significantly reduces noise during unloading and pressure regulation.
  2. Integrated remote control: Solenoid valve integrated directly for electrical remote unloading and multi-pressure control, delivering energy savings.
  3. High interchangeability: Fully compatible mounting dimensions and interfaces with original Yuken S-BSG and standard BSG series for direct drop-in replacement.
  4. 100% functional verification under simulated conditions: Every unit is fully tested across pressure, flow and noise characteristics before shipment, ensuring consistency and reliability.

Application Areas

  • Noise-sensitive hydraulic systems on injection molding and die-casting machines
  • Remote unloading and multi-pressure control in factory hydraulic power units
  • Machine tool and precision equipment hydraulic circuits
  • Industrial and commercial systems requiring quiet operation
  • Energy-saving pump unloading circuits

Expert Maintenance Tips

Ensure the sub-plate mounting surface is clean and flat; tighten to the specified torque. Maintain required fluid cleanliness to protect the low-noise pilot structure. Match solenoid voltage correctly. Periodically check set pressure and unloading noise levels. If noise increases or pressure becomes unstable, first inspect fluid contamination and filters. For long-term storage keep the valve filled with oil and cycle periodically. Always use original-specification seals when servicing.
