REFERENCE STANDARDS AND SPECIFICATIONS
PERFORMANCE FOR ANY APPLICATION In fluid process systems, it is valves which are the controlling elements. They are responsible for stopping and starting flow, throttling or regulating flow, prevention of backflow and for regulating pressure. KVC (UK) Ltd valves are used in a wide variety of applications the following descriptions will provide a simple guide in the selection of these types of valves. GATE VALVES Gate Valves serve as efficient stop valves with flow in both directions. They are used where a minimum pressure drop is important. Gate valves should not be used for Throttling since partially open gate valves display flow characteristics which will not help maintain accurate and consitent flow control. Partially open gate valves may also be damaged by the high velocity across the valve seats. They function best as ON/OFF valves either in the fully open or fully closed position. GLOBE VALVES Globe valves are suited for service where Throttling is required. Globe valve flow characteristics allow accurate and repeatable flow control. Caution should be taken to avoid very close throttling when the pressure drop exceeds around 20%. This close throttling can lead to excessive noise or vibration and can result in damage to the valves and other piping system components. If these conditions are expected please contact KVC (UK) Ltd for advice. SWING CHECK VALVES Swing Check Valves prevent backflow through pipelines. The valves can be installed in horizontal or vertical, upward flow, piping. They can serve to offer resistance to flow and are best suited to low velocity service condiditons. |

GLOBE VALVES
Globe Valves are used where throttling and shut off are required. Close throttling can lead to altered velocities, this leads to excessive noise and vibration which can damage the valve or piping system.
