GATE VALVES are the most commonly used as shutoff valves in the industries. Gate valves are used where minimum pressure drop and bi-directional on-off service is required. Gate valves are not recommended for use for throttling service. Prolonged use in the partially open position is likely to damage seating surfaces. Gate valves are available with different wedge configurations to meet the specific service conditions. Normally gate valves are provided with flexible wedges unless otherwise asked for.
