How to choose a CPVC union ball valve

Short answer: A CPVC union ball valve is a quarter-turn shut-off valve with union ends, so you can remove the valve for maintenance without cutting the pipe. Pick the size to match your CPVC pipe, and check the body material and union design.

What to check

  1. Size: match the valve to the pipe size. M-Tech Valves makes the brass CPVC union ball valve in 20 mm and 25 mm.
  2. Body: M-Tech uses a brass body with CPVC union ends.
  3. Use: hot and cold water CPVC lines in homes, offices and commercial buildings.
  4. Union ends: the union lets you take the valve out and put it back during maintenance. Ask whether the union can be dismantled and re-assembled.
  5. Operation: quarter-turn handle. Check it turns smoothly by hand.

How to fit it

  • Join the union ends to the pipe with CPVC solvent cement.
  • Align the valve with the pipe before tightening the union.
  • Later, the valve can be dismantled and re-assembled for maintenance.

Warranty

All M-Tech Valves products carry a 5-year warranty against breakage and leakage. A defective valve is replaced piece to piece.
