Frequently Asked Questions
What does dry break mean?
A dry break coupling uses a valve-equipped interface to isolate the fluid path during disconnection and limit released coolant. Spillage varies by size and operating conditions; dry break does not mean zero spillage in every situation.
What should I confirm about the dual interlock design?
Request the operating instructions for your selected TF83 configuration. Review the valve-opening, locking and release sequence, along with system isolation requirements, during engineering qualification.
Which sizes and end connections can I request?
The supplied TF83 information lists 1″, 2″ and 3″ reference sizes, with BSPP, NPT / NPTF, tri-clamp flange and hose-barb configurations. Confirm the available size and end-connection combination when requesting a quote.
Can these valves be used with water-glycol coolant?
Water and water-glycol are listed as reference working media. Share the coolant formulation, concentration, temperature and pressure so the body material and EPDM or FKM seal selection can be reviewed.
Are all TF83 configurations interchangeable with FD83?
Compatibility is configuration-specific. The exact part number, mating geometry, dimensions, materials, seals and operating requirements must be assessed before approving a replacement.
Can I request drawings, samples or a custom connection?
Include your required configuration, quantity, drawing and qualification needs in the inquiry. Availability, customization scope and project timing are confirmed during quotation.
