贺德克直动式溢流阀特点,HYDAC直动式溢流阀原理
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
在相对侧，系统压力在端口1工作。
如果液压力低于弹簧压力，阀门保持关闭。
  只有当力较大时，阀打开，流量才能进入端口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
如果系统压力等于弹簧压力，阀门将再次关闭。
注意：端口2的压力增加了打开压力！
如果端口互换或压力调整高于
操作压力大，阀门功能无效。
直动式减压阀
DB06A是一个无泄漏的提升阀，用于限制入口
通过打开出口抵抗弹簧力的压力。
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.
