Description
Ball Valve Plain x BSP
Description
These double union PVC ball valves have excellent corrosion-resistant characteristics and can be dismantled for maintenance and inspection purposes. The ends are interchangeable.
Pressure Rating
PVC ball valves up to 1 1/2" (50mm) have a pressure rating of 15 bar (215 psi) at 20oC.
2" to 4" (63mm to 110mm) PVC ball valves have a pressure rating of 10 bar (159 psi) at 20oC.
As temperature increases the pressure rating is reduced. PVC systems should not be used where temperatures exceed 60oC.
Sizing - Solvent Weld Pipe & Fittings
Imperial (inch) PVC pipe and fittings sizing is not straightforward. They are sized by their nominal bore or approximate inside diameter.
The following table details pipe outside diameters (o.d.) for each imperial size. The inside diameter (i.d.) of the socket end of the corresponding fitting will be the same as the outside diameter of the pipe.

Sizing - BSP Threads
The following table details approximate thread diameters for male BSP threads.
| Nom Pipe Size | 1/2" | 3/4" | 1" | 1 1/4" | 1 1/2" | 2" | 2 1/2" | 3" | 4" |
| Thread Dia mm | 21.0 | 26.4 | 33.2 | 41.9 | 47.8 | 59.6 | 75.2 | 87.9 | 113.0 |
