A double union ball valve has, as the name implies, two unions on it - one on each side. This enables the valve to be unscrewed and removed from the pipeline should the need arise. After the pipeline of union has been serviced or checked the the user can easily reassemble the union and the pipeline without the need to damage any pipes or fittings in the process. 

One of the biggest advantage with using a double union ball valve is that it has a full-bore flow. Which means that no debris can be caught in the valve that might be flowing in the fluid. Which means that these valves very rarely get blocked.

UPVC is safe to use with drinking water and is rigid and extremely durable. UPVC pipes and fittings are resistant to chemical erosion and operate at a wide range of temperatures and pressures. This material has very little if any flex and is fire resistant. 

All our valves are manufactured according to SABS standards.
