API 600 Bolted Bonnet Gate Valve

The API 600 Bolted Bonnet Gate Valve is engineered to deliver reliable shut-off performance in high-pressure and high-temperature industrial applications. Designed and manufactured in strict compliance with API 600 standards, this valve is widely used in oil & gas, petrochemical, power generation, refinery, and pipeline systems, where durability, safety, and long service life are critical.

Our API 600 bolted bonnet gate valves are produced using high-quality ASTM A216 WCB carbon steel, providing excellent mechanical strength, pressure resistance, and temperature tolerance. The robust bolted bonnet design ensures secure sealing and easy maintenance, making it suitable for long-term operation under demanding service conditions. The valve features a full-bore design, allowing unrestricted flow and minimal pressure drop when fully open.

We offer a comprehensive range of specifications to meet diverse project requirements. Standard sizes include 2 Inch (DN50) valves rated at Class 150 LB / PN20, while the full product range covers sizes from 1/2 Inch to 32 Inch. Pressure ratings are available from Class 150 LB up to Class 2500 LB, enabling use in both low-pressure and high-pressure systems. End connection options include Flanged (RF, RTJ) and Butt Weld (BW), ensuring compatibility with various pipeline configurations.

Operation is typically provided via a handwheel, offering smooth and precise control of valve opening and closing. Optional gear operators or actuators can be supplied upon request for larger sizes or higher torque requirements. The wedge gate construction ensures tight sealing in both upstream and downstream directions, contributing to reliable isolation performance.

All valves are manufactured under strict quality control procedures, including material inspection, dimensional checks, pressure testing, and functional testing in accordance with API requirements. In all cases where the Official API Monogram is applied, it is used in conjunction with API Certificate Number 600-0470, demonstrating full compliance with API’s quality management and manufacturing standards.
