Sequence valves

Sun Hydraulics' sequence cartridges are similar to relief cartridges except the pilot is separately drained so that valve setting is not affected by pressure in the outlet port. Sun sequence cartridges can be conveniently applied using many mounting options. Functionally interchangeable with one another (same flow path, same cavity for a given frame size) Offered in five sizes with flow rates up to 120 gpm (480 L/min.) Fully adjustable over a wide range of operating pressures up to and including 5000 psi (350 bar) (6000 psi (420 bar) intermittent) (except air piloted versions)
