High Pressure Discharge Check Valve
The high pressure discharge check valves should be serviced on a regular, preventive
maintenance schedule. Service is recommended every 1,500 hours. The discharge check valve
can be serviced with the sealing head either installed or removed from the high pressure cylinder.
1.
Turn the machine off and observe the appropriate Lockout/Tagout procedures.
Severe injury can result if the machine is not properly locked out. Observe
electrical Lockout/Tagout procedures before proceeding.
Ensure all pressure is relieved or blocked from the hydraulic and high pressure
circuits before proceeding.
2.
Disconnect the high pressure water piping, following the procedure, High and Low
Pressure Water Piping.
3.
Use two, 1-3/16” wrenches to remove the gland nut. The poppet pin, spring and poppet
check valve will normally remain in the gland nut when it is removed. Remove the
components from the gland nut.
4.
Use a magnet to remove the seat from the sealing head.
5.
Inspect the poppet pin for wear and replace the pin if worn.
6.
Inspect both faces of the seat for damage or cracking. A cracked or damaged seat must be
replaced. The seat can be installed with either face toward the poppet valve. If one face is
worn, but the opposite is not, the seat can be reversed, placing the new surface toward the
poppet valve. A slight burr at the hole edge identifies the used side of the seat. If both
faces are worn, the seat must be replaced.
NOTE
The seat, spring and poppet valve should be replaced as a set. If one component
requires replacement, replace all components.
