NSN 4820-01-527-0625
Valve Directional Control
This cartridge valve is furnished in (standard) aluminum housing with 1/4 npt connections to ports 1 and 2; pilot connection 1/8 npt. Housing has 2 mounting holes of 3/4-16 unf. If pilot pressures falls below minimum pressure valve acts as a relief valve. Determine minimum pressure by multiplying maximum possible system pressure by 11, then devide total by 26. When pilot pressure falls below this number valve will function as a pilot operated relief valve. 26:1 pilot ratio.

Npt
A manually or power operated valve having three or more ports. The direction of the flow through the various ports is controlled by either one or more reciprocating slide(s) or spool(s) with recess areas which mate with ports in an integral or replaceable ported sleeve, or one or more poppet(s). It is designed to change the direction of fluid flow from one valve port to another. An off (no flow) position is not a flow pattern. The valve is designed to actuate various components of a fluid system. A power operated valve may have a manual override. For items which stop, start, or change the flow of fluid, see: valve, solenoid. Excludes valve, plug. See also servovalve, hydraulic; body section, working, linear directional control valve; and valve assembly.
