Mirror Finish Brass Balls
The chrome plated brass (CW617N) balls are mirror finished & made under extremely stringent tolerance. This ensures a long life & low operating torque.
Blow out proof stem
The stem is bottom entry. Thus blow out proof. A shoulder on the stem does not allow it to blow out. This makes it possible to change/ remove the handle even when the line is under pressure. Also the slot for stem does not protrude through the ball. Thus in full open or full closed position the fluid does not communicate outside the ball or in any part of the stem area. In the same condition there is no pressure on the stem resulting in seal effectiveness or leading to an increase in torque.
Along with NBR 0-ring we have provided upper & lower seals of PTFE as further protection to seal adding to life of the valve.
This valve is manufactured to EN-13828 and recommended for use with potable water and approved by various plumbing institutes across the world.
