Leakage Acceptance Rates Comparison Metal & Soft Seated …

‘Pressure Testing of Steel Valves’. ‘Pipeline Valves’ such as trunnion mounted ball valves, pressure balanced lubricated plug valves and pipeline slab gate valves are tested to API6D - ‘Pipeline Valves’. API6D now references ISO 5208 leakage rates. The testing requirements differ slightly from API 598 (ISO 5208 is now mirrored to ...

GUIDANCE ON VALVE TYPE SELECTION -b.ricardo

Plug valves – lubricated balanced/sleeved, Lined/expanding/lift. Diaphragm valves – weir/full flow/pinch. Isolation efficiency 1. Soft seated valves should normally be selected only for clean service. Soft seated block valves, such as ball valves, lined plug valves, soft seated gate valves, and butterfly valves can provide a good tight shut

Direct solenoid and solenoid pilot operated valves

non “plug-in” 1. Balanced spool, immune to variations of pressure. 2. Short stroke with high flow. 3. High shifting forces. 4. Checked accumulator guarantees maximum pilot pressure. 5. Powerful return force thanks to the combination of mechanical and air springs. 6. Bonded spool with minimum friction, shifting in a glass-like finished bore. 7.
