Balancer valves (pressure reducing & relief valves)
●平衡阀 BLG系列是一种新型的复合压力控制阀，用于在驱动负载大的工作平台等时，向专用辅助油缸提供任意的平衡压力，以实现平稳的上下驱动动作。它具有减压阀和平衡（溢流）阀的复合功能，即使负载有所增减，只要操作手柄即可自由地改变平衡压力。
●以往需要用减压阀、平衡（溢流）阀以及单向阀构成回路才能实现的平衡功能，现在用一台阀即可完成。

工作原理与特点
复合功能：一台阀替代传统 “减压阀 + 平衡溢流阀 + 单向阀" 的组合回路；
上升时起减压作用，设定辅助缸压力；下降时起平衡溢流作用，防止负载超速下滑；
松开锁紧螺母，旋转调节手柄即可无级调定平衡压力，负载变化时也能灵活调整；
带压力表接口，便于现场压力检测与设定。
典型应用场景
重型工作平台、升降台、起重机的臂架 / 支腿油缸；
煤矿绞车液压站、大型注塑机、压机的平衡回路；
任何需要平稳控制大负载升降、防止失速的液压系统。
安装与使用要点
副板需单独订购，泄油管必须直接、单独回油箱，末端需浸入油面下；
手柄顺时针旋压力升高，逆时针则降低，调好后锁紧螺母固定；
避免长期在高压、大流量下的连续节流，防止油温过高；
按 ISO 标准清洁油路，防止杂质卡滞阀芯。

TOKYO KEIKI BLG-3-B-10
Balancer Valve / Pressure Reducing & Relief Valve
Balancer Valves (Pressure Reducing & Relief Valves)
- The BLG series balancer valve is a new type of composite pressure control valve. It supplies adjustable balancing pressure to dedicated auxiliary cylinders when driving heavy-load work platforms, enabling smooth lifting and lowering motion. It integrates the functions of a pressure reducing valve and a balancing (relief) valve. Even when the load changes, the balancing pressure can be freely adjusted using the operating lever.
- Functions that previously required a circuit consisting of a pressure reducing valve, balancing (relief) valve, and check valve can now be achieved with a single valve.
Model Interpretation
BLG-3: Series code + mounting surface size (3 corresponds to ISO 4401-03 mounting interface, no separate drain port);
B: Pressure adjustment range 1–7 MPa;
10: Design number, specific to the BLG-3 model.
Specifications
Max. operating pressure: 10.5 MPa
Rated flow: 20 L/min
Pressure adjustment range: 1–7 MPa
Weight: 1.8 kg
Mounting: Subplate mounting with separate subplate, port connection Rc 3/8
Suitable fluids: Petroleum-based hydraulic oil, water-glycol; F3 phosphate ester type available as option
Mounting bolts: M5×50 (4 pcs), tightening torque 7–8 N·m
Working Principle & Features
Composite function: One valve replaces the traditional circuit combination of “pressure reducing valve + balancing relief valve + check valve";
Acts as a pressure reducing valve during upward movement to set auxiliary cylinder pressure; acts as a balancing relief valve during downward movement to prevent load overspeeding;
Loosen the lock nut and turn the adjustment knob to steplessly set the balancing pressure, which can be flexibly adjusted even under changing loads;
Equipped with a gauge port for on-site pressure inspection and setting.
Typical Applications
Heavy-duty work platforms, lifting tables, boom and leg cylinders of cranes;
Hydraulic stations for mining winches, large injection molding machines, and balancing circuits for presses;
Any hydraulic system requiring smooth control of heavy-load lifting and preventing stalling.
Installation & Operation Notes
Subplate must be ordered separately; the drain line must be routed directly and independently to the tank, with its end submerged below the oil level;
Clockwise rotation of the knob increases pressure, counterclockwise decreases it; tighten the lock nut after adjustment;
Avoid continuous throttling under high pressure and high flow for long periods to prevent excessive oil temperature rise;
Clean the hydraulic circuit according to ISO standards to prevent contamination from jamming the spool.
