Description
Schedule 80 CPVC Van Stone Flange (SOC) CL150 150PSI
Schedule 80 CPVC Van Stone Flange (SOC) CL150 150PSI provides a detachable Class 150 flange transition for compatible CPVC piping. The socket configuration joins to compatible CPVC pipe while the Van Stone design allows the backing ring to rotate for bolt-hole alignment.
The Schedule 80 CPVC Van Stone socket flange combines a solvent-cement socket connection with a Class 150 bolted flange interface and a specified 150 PSI rating. Selection should account for nominal size, socket compatibility, mating flange requirements, gasket selection, bolt pattern, and proper CPVC installation procedures.

Van Stone Flange Design
The Van Stone flange design uses a separate backing-ring arrangement around the flange hub. This allows the ring to rotate independently for easier bolt-hole alignment with the mating flange.
The flange size and mating flange requirements should be confirmed before ordering. Proper gasket selection, bolt pattern, and flange-face alignment should also be established before final assembly.
Socket Connection
The socket connection accepts appropriately sized compatible CPVC pipe. This interface provides the solvent-cement connection between the piping run and Van Stone flange hub.
Pipe ends and fitting sockets should be clean and properly prepared before assembly. Compatible CPVC primer, solvent cement, insertion procedures, and required cure times should be followed.
Class 150 Flange Connection
The Class 150 flange interface provides a detachable bolted connection to compatible flanged piping or equipment. The rotating ring can help align the bolt holes without rotating the connected CPVC piping.
Bolts should be tightened evenly using an appropriate cross-pattern sequence. The mating flange, gasket, ring, and hub should remain correctly positioned during final assembly.
Schedule 80 CPVC Application
A Schedule 80 CPVC Van Stone Socket Flange provides a serviceable Class 150 flanged transition from compatible CPVC pipe. Its socket interface is intended for properly prepared solvent-cement joining while the flange connection remains mechanically removable.
System temperature, pressure, fluid compatibility, gasket requirements, mating flange compatibility, joining requirements, and applicable installation standards should be reviewed for the intended application. This configuration is identified with a 150 PSI rating.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the socket configuration.
- Confirm Class 150 compatibility.
- Check gasket and bolt requirements.
- Confirm the 150 PSI rating.

Our piping specialists can help review nominal size, socket compatibility, Class 150 flange requirements, gasket and bolt requirements, 150 PSI rating, and installation considerations before you order.
