The direct acting pressure relief valve DB16621E is a

spring-loaded spool valve.

It has an additional tank connection with spring chamber relief.

Cavity (metric) M 33 x 2. Qmax = 300 l/min Pmax = 350 bar

HYDAC direct acting pressure relief valves in spool type

version are spring-loaded spool valves which limit

the pressure in hydraulic systems out of safety reasons.

Different pressure ranges enable an optimal system adjustment

Pressure relief function with external venting of spring chamber

液压系统的压力出于安全原因。

The DB16621E is a direct acting, spool type pressure relief valve with additional

spring-chamber venting. When the pressure at port 1 exceeds the pre-set value,

the spool opens and oil flows from port 1 to tank port 2.

When the valve opens, the leakage bore to port 2 is shut-off.

The additional spring chamber venting at port 3 to

tank ensures that the valve is independent of pressures at port 2.



由于CFD优化流路导致的低压降

也可以用作逻辑元件或卸载阀

Good, flat curve characteristics throughout the flow range

External surfaces zinc-nickel plated and corrosion-proof

Hardened and ground internal valve components to ensure minimal wear and extended service life

Low pressure drop due to CFD optimized flow path

Can also be used as a logic element or unloader valve

Spool orifice available as an option
