Ductile Iron 6 Inch Flange OS&Y Gate Valve

Ductile Iron 6 Inch Flange OS&Y Gate Valve


One type of valve commonly used to control water flow to fire sprinkler systems is known as an OS&Y gate valve. OS&Y means “outside stem and yoke” or "outside screw and yoke".

 

OS&Y gate valves operate by opening and closing via a gate, which lowers into or rises out of the valve. Raising the gate allows water to flow through the valve while lowering the gate cuts off the water flowing through the valve. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

 

Products Features

- Precision-machined valve stem, reduces operating torque.

- Non-toxic powder epoxy resin spraying on botn inside and outside of the valve to enhance corrosion resistance and improve water quality.

- The valve plate is covered with rubber both inside and outside to guaranteed good sealing. It has strong connection to avoid fall off after long-term use.

- Thrust bearings reduce frictional resistance and reduce operating torque.
