Description
PVC Sch. 80 Van Stone Flange (Spigot x Multi Bolt)
PVC Sch. 80 Van Stone Flange (Spigot x Multi Bolt) provides a detachable flanged transition for compatible Schedule 80 PVC piping where a spigot connection is required on the pipe side and a multi-bolt flange connection is required at the mating component. The Van Stone configuration incorporates a rotating flange ring that helps simplify bolt-hole alignment during installation.
The Spigot x Multi Bolt configuration combines a male-style spigot connection with an adjustable bolted flange arrangement for connecting compatible valves, equipment, fittings, or other flanged components. Selection should account for nominal size, receiving socket compatibility, mating flange dimensions, bolt pattern, gasket requirements, system conditions, and available installation clearance.

Van Stone Flange Configuration
The Van Stone configuration uses a rotating flange ring around the fitting hub, allowing the bolt-hole pattern to be positioned independently of the PVC piping connection. This provides additional flexibility when matching the flange to a compatible valve, fitting, equipment connection, or adjoining flanged component.
The adjustable ring is particularly useful when the adjoining piping has already been positioned and precise bolt-hole orientation is required at the connection point. Once the mating flange is aligned, the gasket and bolting can be installed without rotating the connected PVC piping to establish the bolt pattern.
Spigot Connection Design
The spigot connection provides a male-style PVC end designed to fit into an appropriately sized compatible receiving socket. This differs from the socket version of a Van Stone flange because the flange itself supplies the spigot rather than receiving the adjoining pipe within a socket.
The receiving component and spigot should be checked for nominal-size compatibility before permanent joining begins. Proper preparation and the appropriate PVC joining procedure help establish the pipe-side connection while leaving the rotating flange ring available for final bolt-hole alignment.
Multi-Bolt Flange Connection
The multi-bolt flange connection creates a detachable mechanical joint with a compatible mating flange. A suitable gasket is positioned between the flange faces, and the required fasteners secure the connection while allowing future disassembly when access to the connected component is necessary.
Mating flange dimensions and bolt-hole compatibility should be confirmed before ordering because the bolted connection must align correctly without forcing the piping into position. The flange faces should meet evenly, with the gasket properly centered before the fasteners are progressively tightened.
Serviceable Flanged Connection
A Van Stone flange provides a convenient serviceable connection point where PVC piping interfaces with valves, equipment, or other compatible flanged components. The bolted joint can be separated when maintenance or component replacement requires access without permanently joining the two flange faces.
The surrounding piping should be independently aligned and supported so excessive weight or mechanical strain is not transferred to the flange connection. Adequate working space should also be maintained around the flange for gasket placement, bolt installation, tightening, inspection, and future disassembly.
Installation & Selection Considerations
- Confirm the nominal pipe size.
- Verify Schedule 80 PVC compatibility.
- Confirm the mating flange bolt pattern.
- Match the receiving socket connection.
- Allow clearance for flange assembly tools.
Our PVC fitting specialists can help review your nominal size, Schedule 80 requirements, spigot connection, receiving socket, mating flange dimensions, multi-bolt pattern, gasket requirements, and available installation clearance before you order.
Frequently Asked Questions
What is a PVC Sch. 80 Van Stone Flange used for?
It provides a detachable flanged transition between compatible Schedule 80 PVC piping and a mating flanged valve, fitting, equipment connection, or piping component.
What does Spigot x Multi Bolt mean?
The pipe side provides a spigot connection for a compatible receiving socket, while the opposite side uses a multi-bolt flange connection.
What is a Van Stone flange?
A Van Stone flange incorporates a rotating flange ring that allows the bolt-hole orientation to be adjusted independently of the connected PVC piping.
How does the spigot connection differ from a socket connection?
A spigot end fits into a compatible receiving socket, while a socket end is designed to receive compatible pipe or another suitable spigot connection.
Why is the rotating flange ring useful?
The rotating ring makes it easier to align the bolt holes with the mating flange without rotating the connected PVC piping.
Is a gasket required between the flange faces?
A compatible flange gasket is typically positioned between the mating flange faces as part of the completed bolted connection.
Should flange bolts correct piping misalignment?
No. The piping and mating component should be properly aligned before tightening rather than pulling misaligned components together with the flange bolts.
What should I confirm before ordering?
Confirm the nominal size, Schedule 80 PVC requirement, spigot connection, receiving socket, mating flange dimensions, bolt pattern, gasket requirements, and installation clearance.
Important Ordering & Installation Notes
- Clean both mating flange faces.
- Center the gasket before bolting.
- Inspect the spigot before assembly.
- Tighten fasteners evenly in sequence.
- Align piping independently of the flange.
