A Control Valve Screw Plug is a threaded cylindrical metal piece with a head for easy tightening and loosening. It screws into a threaded port on a hydraulic system, acting as a secure barrier against leaks and ensuring smooth operation. Unlike quick-connect or push-in plugs, screw plugs offer exceptional pressure-holding capability and are ideal for permanent or semi-permanent closures.Attributes:• Keeps precious fluids contained and prevents costly spills or contamination• Withstands immense hydraulic forces, safeguarding the system's integrityApplications:A Control Valve Screw Plug is used to securely seal ports on a piston pump, preventing fluid leaks and maintaining system pressure. It is used to protect the internal components of the piston pump by preventing contamination.
