Spool Type, Direct Acting, Metric Cartridge – DB16621E-10
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, it shuts off the leakage bore to port 2. The additional spring chamber venting at port 3 to tank ensures that the valve is independent of pressures at port 2.
See datasheet for drawings, dimensions, model code, etc…
