TGMC-3-PT-Fw-50 TOKYO KEIKI 东京计器溢流叠加阀TGMC-3-PT-FW-50是液压系统中常用的压力控制元件，其核心特点是采用叠加式安装结构，适配集成化液压系统，具体特点如下：

1. 安装便捷，结构紧凑

   叠加式溢流阀无需额外的连接块或管路，可直接叠加在液压阀块、执行元件或其他叠加阀之间，通过螺栓紧固即可完成安装。这种结构大幅减少了管路接头数量，节省了安装空间，特别适合小型化、集成化的液压系统。

2. 管路简化，减少泄漏

   传统板式溢流阀需要通过油管与系统连接，存在管路长、接头多、泄漏点多的问题。叠加式溢流阀借助自身的通油孔道与相邻元件直接连通，取消了外部连接管路，有效降低了液压油的泄漏风险，同时也减少了管路压力损失和振动噪声。

3. 配置灵活，扩展性强

   叠加式溢流阀可以与同规格的叠加式换向阀、节流阀、单向阀等元件任意组合叠加，根据系统需求灵活配置液压回路。在需要调整系统功能时，只需增减或更换叠加阀的种类和数量，无需改动整体管路布局，维护和改装成本低。

4. 通径规格统一，互换性好

   叠加式溢流阀通常遵循标准化的通径规格（如 NG6、NG10 等），同规格的不同品牌产品可直接互换，提升了系统的通用性和备件管理的便利性。

5. 压力控制稳定，响应较快

   从控制性能上，叠加式溢流阀与传统板式溢流阀原理一致，通过弹簧力与液压力的平衡来控制系统压力，具备压力稳定、调压精度较高、响应速度快的特点，能有效防止系统过载。

6. 存在一定的压力损失限制

   由于其通油孔道集成在阀体内，流道相对固定，相较于管式或板式阀，在大流量工况下可能产生略高的压力损失，因此更适合中小流量的液压系统。

Product Features

TGMC-3-PT-FW-50 is a widely used pressure control component in hydraulic systems, featuring a stack-mounted structure ideal for integrated hydraulic systems.

Easy installation & compact structure

Stack-type relief valves require no additional connection blocks or piping. They can be directly stacked between hydraulic manifolds, actuators, or other stack valves and secured with bolts. This design greatly reduces the number of pipe joints, saves installation space, and is especially suitable for compact, integrated hydraulic systems.

Simplified piping & reduced leakage

Unlike conventional plate-type relief valves with long external lines and multiple leakage points, stack valves connect directly to adjacent components through internal oil passages. This eliminates external tubing, effectively lowering the risk of hydraulic oil leakage, while also reducing pressure loss and vibration noise.

Flexible configuration & high expandability

This relief valve can be freely combined and stacked with other stack-type valves of the same size (directional valves, throttle valves, check valves, etc.) to build hydraulic circuits as needed. System functions can be modified by adding, removing, or replacing stack valves without changing the main piping layout, resulting in low maintenance and retrofit costs.

Standardized size & good interchangeability

Stack valves follow standardized nominal sizes (such as NG6, NG10). Products of the same size from different brands are interchangeable, improving system versatility and spare parts management.

Stable pressure control & fast response

Based on the same working principle as conventional plate-type valves, it controls system pressure by balancing spring force and hydraulic pressure. It delivers stable pressure, high adjustment accuracy, and fast response, effectively protecting the system from overload.

Pressure loss characteristics

Since oil passages are integrated inside the valve body, pressure loss may be slightly higher under large-flow conditions compared to pipe or plate valves. Therefore, it is more suitable for small-to-medium flow hydraulic systems.
