VALVES & ACCESSORIES

Gate valve is bi-directional isolating valves, and it opens by lifting a round or rectangular gate out of the path of water flow. When fully open, gate valve has no obstruction in the flow path, resulting in very low friction loss. The actuator of gate valve connects either a rising steam (outside screw and yoke, OS&Y) or a non-rising stem (NRS), so to form different type.
