7.3.1 Discharge HP Check Valve
The HP discharge check valve can be serviced with the sealing head
either installed in or removed from its intensifier HP cylinder.
1.
Remove the gland nut from the sealing head using a pair of wrenches.
2.
When the gland nut is removed, the spring guide and spring will
normally stay in the gland nut. The seat is removed with a magnet.
Inspect the seat for damage or cracking. A cracked seat should be
replaced. The seat is symmetrical, and can be installed with either face
toward the poppet. Note that a slight burr at the hole edge identifies the
used side of the poppet seat. When reinstalling the seat, apply a thin
film of High Purity Goop to both faces. Install the seat into the sealing
head with the best surface facing the check poppet.
