Brass Ball Valves Couple-Collector Valves are used usually in building facilities, floor heating systems and warm and cold building water supply networks. The valve is quarter-turn and opens and closes with 90 degree rotation of handle. Internal and external surfaces are coated with nickel to avoid long-term corrosion against minerals of water or other enviromental corrosives. The ball inside the valves is covered with chromium in addition to nickel to minimize its erosion due to friction with plastic tape. Sealing angle of this type of valves is +15 degrees, the best sealing angle for ball valves. A total of 100% pressure test is performed on all valves during pre-defined time period, and torque test and impact test are performed randomly too.
