DescriptionHattersley gate valves offer the ultimate in dependable service wherever minimum pressure drop is important.They serve as efficient stop valves with fluid flow in either direction. The straight through design offers little resistance to flow and reduces pressure drop to a minimum. A gate-like disc - actuated by a stem screw and handwheel - moves up and down at right angles to the path of flow, and seats against two seat faces to shut off the flow. Gate valves are not recommended for throttling since the control characteristic is not appropriate and subsequent damage due to erosion may prevent the valve providing an effective shut off.
