TGMC-3-PT-Fw-50 TOKYO KEIKI 東京計器溢流疊加閥TGMC-3-PT-FW-50是液壓系統中常用的壓力控制元件，其核心特點是采用疊加式安裝結構，適配集成化液壓系統，具體特點如下：

1. 安裝便捷，結構緊湊

   疊加式溢流閥無需額外的連接塊或管路，可直接疊加在液壓閥塊、執行元件或其他疊加閥之間，通過螺栓緊固即可完成安裝。這種結構大幅減少了管路接頭數量，節省了安裝空間，特別適合小型化、集成化的液壓系統。

2. 管路簡化，減少泄漏

   傳統板式溢流閥需要通過油管與系統連接，存在管路長、接頭多、泄漏點多的問題。疊加式溢流閥借助自身的通油孔道與相鄰元件直接連通，取消了外部連接管路，有效降低了液壓油的泄漏風險，同時也減少了管路壓力損失和振動噪聲。

3. 配置靈活，擴展性強

   疊加式溢流閥可以與同規格的疊加式換向閥、節流閥、單向閥等元件任意組合疊加，根據系統需求靈活配置液壓回路。在需要調整系統功能時，只需增減或更換疊加閥的種類和數量，無需改動整體管路布局，維護和改裝成本低。

4. 通徑規格統一，互換性好

   疊加式溢流閥通常遵循標準化的通徑規格（如 NG6、NG10 等），同規格的不同品牌產品可直接互換，提升了系統的通用性和備件管理的便利性。

5. 壓力控制穩定，響應較快

   從控制性能上，疊加式溢流閥與傳統板式溢流閥原理一致，通過彈簧力與液壓力的平衡來控制系統壓力，具備壓力穩定、調壓精度較高、響應速度快的特點，能有效防止系統過載。

6. 存在一定的壓力損失限制

   由于其通油孔道集成在閥體內，流道相對固定，相較于管式或板式閥，在大流量工況下可能產生略高的壓力損失，因此更適合中小流量的液壓系統。

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.
