In-Depth Technical Descriptions:
Meticulous Construction
The construction of our steel gate valves adheres to API 600 and BS 1414. Featuring yoke, flange, or welded designs with unrestricted flow rates and flexible or fixed wedges, these valves boast cast bodies, covers, and yokes. Wedges may be forged or cast and are universally guided. Sealing seats are bolted or welded into the body, with overlays depending on the trim. These valves include a rising non-rotative spindle and a bolted body-cover joint. Standard spindle threads are ACME2G-LH.
Handwheel operation is standard. Upon mutual agreement, options for angle transmission, electric actuator, or pneumatic actuator are available. Larger diameter gate valves can be equipped with bearings for easier control. Sealing materials include pressed rings from expanded graphite and graphite-plaited rings, meeting the Clean Air Act Amendment of 1990. Additional features such as drainage, venting, relief from inter-space, and bypasses can be provided upon special request.
Design Dimensions
Standard design dimensions are detailed in the table below.
Material Design Variety
Gate valves are available in various material options to suit different needs.
Versatile Assembly
Yoke gate valves can be installed in any position within the pipeline.
Rigorous Testing
Gate valves undergo stringent pressure tests in line with API 598 standards, ensuring strength, backseat tightness, and closure tightness at both low and high pressures (upon request).
