A defined relationship between valve position and coupling action. Built for controlled isolation, service and replacement within liquid cooling circuits.
Product appearance illustration. Materials, interfaces and markings follow the order configuration.
01
Full-flow path
A ball-valve flow path for the main connection. Review flow and pressure drop for the selected configuration.
02
Sequenced interlock
Valve position and separation are mechanically related to establish a defined operating sequence.
03
Multiple end configurations
Clamp, threaded, hose-barb and project-specific ends are confirmed against drawings.
01 / OPERATION
Four actions. One controlled service path.
NP83 / INTERLOCK SEQUENCE
A CONTROLLED SERVICE SEQUENCE
Align & couple
With both valves closed, dock the coupling, rotate to its coupling stop and check the alignment marks.
Appearance and sequence illustration. Follow the instructions for the supplied configuration.
Follow system isolation and pressure-management procedures for the actual fluid and residual pressure. The interlock is not a substitute for system safety procedures.

NP83 / APPLICATION ENGINEERING
Build your application brief.
Define the connection task before confirming the assembly. Select what you know and carry the brief into your engineering inquiry; unresolved items can be discussed with our team.
04 / ENGINEERING QUESTIONS
Resolve the right questions before selection.
How does NP83 relate to equipment-side quick disconnects?
Select by service location, bore, available space and operating requirements. Different families are not automatically interchangeable.
Do the image markings define the supplied material?
No. Images illustrate appearance. Approved drawings and the order configuration define materials, seals and markings.
What information is needed for selection?
Provide fluid and concentration, pressure and temperature, flow, bore, mating drawing, service procedure and required inspection documentation.
Are flow, pressure-drop or spillage guarantees listed here?
This page does not state unverified quantitative guarantees. Define the required tests and acceptance criteria for the target configuration, then confirm available records.
