API 6A Wellhead PR2 Valve in Oil and Gas Wells with EE FF HH Materials

Shengji PR2 valve is designed to suit severe oilfield conditions. It is mainly used in oil/gas wells with high performance requirements. Shengji 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.

Non-elastomer combined seals for stem seals and seals between seat and body.

Metal to metal seal between seat and gate & body and bonnet.

Back seal design between stem and bonnet allows stem seal change under pressure

Hard alloy spray on the surface of valve gate and seat.

Excellent performance of anti-corrosion and anti-abrasion

Heat treatment and elaborate machining for pressure containing/pressure control parts. Small rotating torque.

Shengji PR2 valve test is certified by DNV. Its performance meets the full requirement of the PR2 standard.
