PR2 gate valve
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.
- 25 years PR2 gate valve manufacturing experience
- The strictest quality standards on PR2 gate valve
- Full support on your customised requirement
The Sanjack PR2 valve is designed to suit severe oilfield conditions.
It is mainly used in oil/gas wells with high performance requirements.
Sanjack 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.

Wellhead Equipment Testing Lab
Sanajck is the SINOPEC designated well control experimental base, it owns the first international advanced well control equipment test device in China, and can take all kinds of water pressure and air pressure sealing test, the maximum pressure can reach to 35000psi. All the test processes are controlled by computer.
The base provides reliable quality guarantee for Sanjack well control products.
This PR2 testing device can perform dynamic test and air tightness test in high and low temperature, pressure and temperature cycling test.The highest temperature can reach 150℃ and lowest -70℃。This device was proved achieving national level by DNV.
PR2 Valve Test Data
- 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
