GUIDANCE ON VALVE TYPE SELECTION -b.ricardo
GUIDANCE on Valves Type SELECTION VALVE TYPE SELECTION . VALVE type SELECTION should take account of : 1. Required function. 2. Service conditions. 3. Fluid type and condition. 4. Fluid characteristics. 5. Frequency of operation. 6. Isolation requirements. 7. Maintenance requirements. 8. Environmental considerations. 9. Past experience in comparable conditions. and size. 1. Required VALVE function and description Isolation (block) valves Valves intended for starting and stopping flow or for isolation of equipment generally be selected to provide: Low resistance to flow (low pressure drop) by means of a straight through flow configuration which may also facilitate line clearing. Bi-directional sealing providing good shut off when the flow or pressure differential is from either direction.
Method to achieve valve shut off Diaphragm/Pinch √ Globe √ Plug (expanding and wedge (lift) type) √ Plug (sleeved, lubricated balanced) √ Butterfly √ Ball (floating and trunnion mounted)√
