Gate valves are of rising stem, outside screw and yoke (OS & Y) and with bolted bonnet construction. The rising stem indicates open or close position of the valve. The outside screw ensures easy lubrication and prevents corrosion and erosion by line fluids. The gate valves are used where minimum pressure drop and or bi directional on-off service are required.
