Description
Schedule 80 PVC Van Stone Flange DIN
Schedule 80 PVC Van Stone Flange DIN provides a flanged transition for compatible Schedule 80 PVC piping systems requiring a DIN flange configuration. The Van Stone design separates the piping-side hub from the flange ring, allowing the ring to be positioned independently for easier bolt-hole alignment with a compatible DIN mating flange.
The DIN Van Stone flange configuration combines Schedule 80 PVC construction with an adjustable flange arrangement intended for compatible DIN-pattern connections. Selection should account for nominal size, DIN flange requirements, mating flange compatibility, piping-side connection requirements, gasket selection, bolt-hole alignment, service conditions, piping support, and available installation clearance.

DIN Flange Configuration
The DIN flange configuration identifies the mating flange arrangement associated with this Van Stone flange and should be matched to the requirements of the adjoining DIN-pattern component. Confirming the correct flange configuration is important because bolt-hole arrangement and mating dimensions must correspond with the intended flanged connection.
The mating flange, gasket, and fastener requirements should be reviewed together before installation begins. Verifying these components in advance helps establish compatibility at the connection while providing adequate room for gasket positioning, fastener installation, flange alignment, and future service access around the completed assembly.
Van Stone Flange Design
The Van Stone design uses a separate flange ring around the piping-side hub instead of fixing the bolt-hole orientation permanently to the hub. This arrangement allows the ring to be positioned independently during assembly, simplifying alignment with a compatible DIN mating flange after the piping connection has been established.
Independent ring positioning can be especially useful where the adjoining piping determines the hub location before the final flange joint is assembled. The flange ring can then be aligned with the mating bolt pattern without rotating the connected piping solely to obtain the required fastener orientation.
Bolted Flange Connection
The bolted flange interface joins the Van Stone flange to a compatible DIN mating flange using the appropriate gasket and fastener arrangement. Proper alignment allows the flange faces to meet naturally and helps prevent the bolts from being used to pull misaligned piping or components into position during assembly.
The gasket should remain correctly centered while the fasteners are installed and tightened progressively using an appropriate sequence. Even tightening helps distribute assembly forces around the flange joint while independent piping support reduces bending, twisting, and other external loads transferred into the completed connection.
Schedule 80 PVC Integration
A Schedule 80 PVC Van Stone Flange DIN provides a practical transition where compatible Schedule 80 PVC piping must interface with a DIN-pattern flanged component. The Van Stone arrangement adds installation flexibility by allowing final bolt-hole positioning to be coordinated independently from the orientation of the piping-side hub.
Application suitability should be evaluated using the requirements of the complete piping system rather than the Schedule 80 designation alone. DIN flange compatibility, service conditions, piping-side connection requirements, gasket selection, fastener requirements, piping support, installation environment, and applicable practices should all be considered during selection.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the DIN configuration.
- Check Schedule 80 PVC compatibility.
- Confirm the required mating flange pattern.
- Allow clearance for ring and bolt alignment.
Our PVC fitting specialists can help review your nominal size, Schedule 80 requirements, DIN flange configuration, mating flange pattern, piping-side connection, gasket requirements, bolt alignment, service conditions, adjoining piping support, and available installation clearance before you order.
Frequently Asked Questions
What is a Schedule 80 PVC Van Stone Flange DIN used for?
It provides a flanged transition between compatible Schedule 80 PVC piping and an appropriately matched DIN-pattern flanged component.
What does DIN identify on this flange?
DIN identifies the flange configuration that must be matched with the requirements of the intended mating flange connection.
What is a Van Stone flange?
A Van Stone flange uses a separate flange ring around the piping-side hub so the ring can be positioned independently for bolt-hole alignment.
Why is the adjustable flange ring useful?
It allows the bolt-hole orientation to be adjusted without rotating the connected piping solely to align the flange fasteners.
Does the mating flange need to use a compatible DIN pattern?
Yes. The mating flange configuration must correspond with the DIN flange arrangement required for the completed connection.
Why should the gasket requirements be checked before installation?
The gasket must be appropriate for the mating flange assembly and intended service so it can be positioned correctly between the flange faces.
Important Ordering & Installation Notes
- Inspect flange faces before use.
- Center the gasket before bolting.
- Position the flange ring before assembly.
- Tighten flange fasteners evenly in sequence.
- Support adjoining piping independently of the flange.
