RockySea Petro PR2 Gate Valve



  • Full support on your customised requirement
  • The strictest quality standards on PR2 gate valve
  • 25 years PR2 gate valve manufacturing experience
PR2 gate valves are designed for high performance wellheads and christmas tree in Oil or gas recovery wells, especially the gas wells that containing H2S or CO2 in high volume.


Description 

The RockySea Petro PR2 valve is designed to suit severe oilfield conditions. It is mainly used in oil/gas wells with high performance requirements. RockySea Petro is a DNV verified anti-H2S Christmas tree valve manufacturer, with both the PR2 valve and the PR2 valve testing devices duly certified by the DNV. To be so certified, the PR2 valves undergoes 160 open/close dynamic cyclic tests at room temperature, 20 such cycles at 121 Celsius degree, 20 dynamic cyclic pressure tests at -60 Celsius degree, and 3 instances of high/low dynamic temperature pressure tests. PR2 valves are more durable than PR1 valves. Seals are reliable and service life can reach 20 years.
