Section 3: Preparation for Use
3.0 BEFORE PUTTING 40K MULTI-MODE VALVE INTO SERVICE
NEW 40K MULTI-MODE VALVE
3.1 Check the Multi-Mode Valve carefully upon removal from its shipping
container for damage. DO NOT use the product if any damage is appar-
ent. Instead, notify Jetstream immediately if the condition of any compo-
nent is questionable.
3.2 Fill air lubricator with oil per Section 6.2.
3.3 Remove cartridge from packaging and check condition of seals.
Before installing according to the instructions in Section 6.1, check the
bore into which the cartridge is to be installed and verify that it is free
of packaging materials or other debris that could result in improper or
inconsistent operation or plugging of nozzles which could cause system
overpressurization.
3.4 Determine the mode in which the valve will be used from the Product
Configuration section and configure the dump port accordingly based on
Figure 1.
3.5 Follow all pre-startup procedures prior to putting a new Multi-Mode
Valve into service.
Do not use a Multi-Mode Valve that has not had the fol-
lowing procedures and inspection previously performed on it.
PREVIOUSLY USED 40K MULTI-MODE VALVE
For safety reasons, the following cleaning and inspections must be per-
formed on the control valve before the start of each working shift.
3.6 Remove the valve cartridge from the control valve body for inspec-
tion. The cartridge’s valve stem surface should be smooth and the valve
should move freely in cartridge. The cartridge seals should be free of
damage. Replace the cartridge if damage or wear to any component is
apparent.
