微信打开Oliver Valvetek offers a range of Rotary Gate Valves with nominal bore sizes of 3/8″ [9.5mm] and 1/2″ [13mm].
The small-bore subsea rotary valves are qualified at different pressure ratings of up to 15,000psi [1034 bar] and 16,500 PSI [1138 BAR] – 1.65 X CWP seat test was also conducted (if the system is rated at 10,000 psi). Rotary Gate Valves are suitable for water depths to 10,000 ft [3050m].
Qualification testing is performed to the exacting standards of API 6A Appendix F PR2 and 17D 2nd Ed (Operable temperature range: -20F [-29C] to +350F [+177C] with non-operable temperature range: -50F [-46C] to +350F [+177C].
The rotary valves offer a good alternative to a needle valve where typically you would expect to have low operational torques but high torques to damage. Another design feature is that should the rotary gate valve be over-torqued and extrenal valve stops are compromised, the valve will continue to rotate without damaging the internals.
