Installation - Graco Uniblock Series Instructions Manual

Installation

The USP Valve should be ready to install in your sys-
tem. It has been factory-tested and should not require
any additional modification.
As long as lubricant is supplied under pressure, the
valve will continue to operate . Whenever lubricant flow
ceases, the valve pistons stop. When flow resumes, it
will start again at the same point in the discharge cycle.
NOTE: The manufacturers of the machine tool and its
component bearings should be consulted to ensure that
the ISO 18/14 cleanliness level is adequate.
Outlet Adapters
Each block ships with the correct number of outlet
adapters and seals. Install one adapter into each open
outlet port. Be sure a seal is installed on each outlet
adapter.
Outlet adapters have standard threads for interfacing
with tube fittings.
NOTICE
Supplied outlet adapters are required for full func-
tionality and testing.
Recommended Tube Fittings
• Fittings should have a maximum 9/16 in. (14 mm)
