賀德克直動式溢流閥特點,HYDAC直動式溢流閥原理
The spring acts with a certain force on the piston and presses it on the valve seat.
On the opposite side the system pressure works at port 1.
If the hydraulic force is lo

FEATURES - All exposed surfaces corrosion-proof - 
All valve parts made of high-strength steel with 
hardened and ground components to ensure minimal wear and extend service life - 
Fast response - Adjustable under full system pressure - 
Adjustable over the u.m. pressure range - 
Various pressure ranges up to 350 bar - 
Poppet type valve with damped characteristics
在相對側，系統壓力在端口1工作。
如果液壓力低于彈簧壓力，閥門保持關閉。
  只有當力較大時，閥打開，流量才能進入端口2（油箱）。
Only if the force is higher, the valve opens and the flow will be let to port 2 (tank). 
If the system pressure is equal to the spring pressure the valve closes again. 
Attention: Pressure at port 2 increases the opening pressure! 
If ports are interchanged or  the pressure adjustment is higher than 
the operating pressure, the function of the valve is invalid.

The direct acting pressure relief valve 
DB06A is a leakage-free poppet valve used for limiting the inlet 
pressure by opening the outlet against spring force. 
Cavity UNF 9/16-18. Qmax = 20 l/min Pmax = 350 bar
如果系統壓力等于彈簧壓力，閥門將再次關閉。
注意：端口2的壓力增加了打開壓力！
如果端口互換或壓力調整高于
操作壓力大，閥門功能無效。
直動式減壓閥
DB06A是一個無泄漏的提升閥，用于限制入口
通過打開出口抵抗彈簧力的壓力。
腔UNF 9 / 16-18。 Qmax = 20l / min Pmax = 350巴
The Pressure relief valve DB06C is a direct acting, 
spring loaded valve with damped characteristics. 
Its job is to limit the pressure in the system.
