nnection 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

The DB16621E is a direct acting, spool type pressure relief valve with additio
nal
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 additio
nal 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 compo
nents 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
