10.3
Replacing Valves
Two types of valves may be supplied with various models of the M06 series pumps.
They are disc valves and AR (Abrasion Resistant) valves. The disc valves are the most
commonly used valves.
A minimum of approximately 3 feet (0.9 m) of clearance is required above the fluid
cylinder to allow valve service without removal of the fluid end. If sufficient clearance is
not available, the fluid end must be removed as outlined in previous section for valve
service. The following procedure is written under the assumption that sufficient
clearances exist.
WARNING
Many accidents occur every year through careless use or service of
mechanical equipment. You can avoid hazards associated with high-
pressure equipment by always following the safety precautions listed in
Section 1.0.
CAUTION
CHECK TO ENSURE THAT THE POWER IS LOCKED OUT AND
TAGGED OUT.
1. Loosen the hex plugs (77) on the top of the fluid cylinder if
threaded covers are supplied or the nuts (58) that retain the
three valve covers (44). Remove the valve covers.
2. For AR type valves refer to section 10.3.1. This section
describes the methods for removing and installing the AR
valves.
3. For disc type valves refer to section 10.3.2. This section
describes the methods for removing and installing disc
valves.
