ASSEMBLY
1.
Install the pipe plug (31) in the valve body (3). Do not overtighten the pipe plug.
2.
Install the packing (30) in section (4).
3.
Insert the spring (28) into the poppet (29), then insert both into the section (4).
4.
Install the packing (27) and reinforcing ring (26) into the section (4) and secure them with the pipe plug (25). Do not
overtighten the pipe plug.
5.
Place the packing (24) in position on the valve spool (23). Lubricate the valve spool with clean hydraulic fluid and
insert the valve spool into the section (4).
6.
Install the retainers (20), flat retainer (22), spring (21), and valve guide (19) into the section (4). Secure them with the
guide mounting machine screw (18). Align the flat retainer by shifting the valve spool (23). Spool bind is an
indication of retainer misalignment.
7.
Install the end cap (17) and secure it with the capscrews (16).
8.
Lubricate the valve subassembly (15) with clean hydraulic fluid and install the valve subassembly, spring (14), and
packing (13) and secure them with the valve plug (12).
9.
Install the pipe plug (11) if it was removed during disassembly.
10. Install the plate packing (10) and plate (9) and secure the plate with the capscrews (8).
11. Install the packing (6 and 7) in the sections (4 and 5) using petrolatum to hold them in place during assembly.
12. With the mounting feet on a flat surface, carefully place the valve body and sections (3, 4, and 5) together. Secure the
sections with the section mounting studs (2) and hex nuts (1). Torque the hex nuts to 55 to 60 lb-ft (75 to 81 Nm).
13. Check that the valve spool (23) moves freely in the bore after torquing the hex nuts (1).
