PVC U TRANSPARENT BALL VALVE



New in our product range d 20 mm - d 63 mm
 
 
 





Together with our partner, we develop and design 2/2 way ball valves for water engineering made of PVC U Transparent.

The 2-way ball valve is designed in the version screw connection with adhesive socket and can also be offered with internal thread connections made of PVC U gray, if required.

The ball valve housing, the inserts and the union nuts are made of the material PVC U Transparent. The valve seat is made of PTFE and the O-rings can be optionally supplied in EPDM and FPM. The handle for shutting off the ball valve consists of the material ABS.

The ball valve can be operated with an operating pressure of max. 10 bar, are operated at a temperature of 20 ° C. When using the fitting, always observe the pressure-temperature diagram for PVC U Transparent. We are happy to answer your inquiries.

PVC TRANSPARENT - APPLICATION EXAMPLES -


In addition to the standard PVC transparent fittings and pipes, we also offer so-called. Processing in PVC U Transparent. Both for the DIN and the inch tube, here offer many possibilities in the production.

Please note :
- in the optical viewing, the possibility of the bluish appearance of PVC U Transparent in inches and also in the DIN range.
- When gluing PVC U Transparent, the color of the bond changes and looks slightly whitish.
- Welding with transparent wire is a common joining technique, but the weld is no longer transparent.

Our other production possibilities:
- Cuts according to customer specifications
- Attach threaded connections
- Attaching outlets
- Pipe fittings according to customer specifications etc.

We will gladly make you a free non-binding offer.
