Installation; Pressure Relief Procedure - Graco USP 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: Graco specifies a cleanliness level of ISO 18/14.
Consult with the manufacturers of the equipment the
lube system is installed on to confirm the equipment
does not require a higher cleanliness level.
