RISING STEM (OS&Y) AND NON-RISING STEM (NRS) GATE VALVES
Gate valves are multi-turn valve with full port flow path. They are ideal for full open and full closed position and are available in rising stem or Non-rising stem configuration. They are available with flanged ends, butt-weld ends, and socket-welded and screwed end. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. They are equipped with handwheels and are available with bevel gears, spur gears, electric, pnuematic and hydraulic actuators.
