	Direct operated, fast response pressure relief valve Three mounting styles Three pressure adjustment options Seven pressure adjustment ranges available for maximum resolution For minimum pressure setting, consult factory

General Description
Pressure relief valve Model DBD are direct operated poppet type valves. Superior pressure verses flow characteristics permit application as a main system, port, or crossport relief. Three mounting styles include: screw-in cartridge valve, cartridge in threaded housing, and cartridge in subplate mounted housing. Three pressure adjustment options include: Screw adjustment with locknut and protective cap, Hand-knob/hand-wheel, and lockable hand-knob.

ZDB
ZDBK

General Description
Pressure relief valves Models ZDB 6 and 10, are cast iron pilot operated poppet style sandwich valves for stacking assemblies. Excellent pressure versus flow characteristics permit use as P, A, or B port relief valves. Models Z2DB 6 and 10 will accept a second relief cartridge for use as dual work port relief valves. Models ZDBK 6 and 10, Z2DBK 6 and 10 are aluminum valves rated to 3000 PSI.
