Valves:
MV3 Valve, ComboValve®, control valves, and deadman valves should be
disassembled and inspected quarterly, or more frequently if heavily used. Ball valves should
open and close without difficulty and should not leak air. Repair or replace any component that
shows signs of damage. Replace parts as needed with Schmidt® original factory replacement
parts furnished by an authorized Schmidt distributor.
Refer to valve drawings in Section 9.0 and
specific valve maintenance manual.
Depressurize vessel before performing any maintenance. See Section 6.2. Removing
components with the abrasive blaster pressurized will result in serious injury or death.
Use of replacement components that are not Schmidt® original factory replacement parts may
result in equipment failure which can result in serious personal injury.

ComboValve® Blowdown Hose:
The blowdown hose (#9) that passes through the
ComboValve (#4) is a 3/4" blast hose. Abrasive carry-over will thin the blowdown hose wall
and eventually wear a hole through the hose. Excessive thinning will prevent the ComboValve
pinch ram from sealing the exhaust flow and result in equipment malfunction. The abrasive
carry-over will also wear the pipe fittings upstream. See Figure 8.4. Depressurize the abrasive
blaster per Section 6.2 and check hose condition weekly. Replace as needed. When replacing
the blowdown hose (#9) also replace the pipe fittings upstream of the valve. These fittings are
the 1-1/4” x 3” VBS II Restrictor, 1-1/4” tee, and the 1-1/4” pipe plug (see Figure 8.4).
