  • Introduction

JASON O&G Check Valves are used in high-pressure pipeline. We provide both standard and reverse-flow check valves. They are designed to prevent reverse fluid flow.


The valve body is forged from high strength alloy steel with inner parts adopting stainless steel to ensure excellent corrosive resistance and longer service life.


JASON O&G has also developed check valves for H2S service in accordance with NACE MR0175 criteria with 1.5 " to 3 " bore sizes and 10,000psi to 15,000psi rated pressure.


JASON O&G provides a customized design to meet each customer’s unique requirements.
