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...

Features:

• Pressure relief function with external venting of the spring chamber
• Good, flat curve characteristics throughout the flow range
• External surfaces zinc-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
• Adjustable throughout flow range
• Possible to use it as a logic element or unloader valve
• Spool orifice available as an option.
