Technical Descriptions:
Construction
The construction of steel gate valves by MSA adheres to the highest standards, aligning with API 600 and BS 1414. These versatile gate valves boast various yoke, flange, or welded configurations, ensuring an uninterrupted flow rate. They feature flexible or fixed wedges, with bodies, covers, and yokes all meticulously cast. Wedges can be either forged or cast, all of which are expertly guided. The sealing seats are securely bolted or welded into the body, with overlay materials depending on the specified Trim. Valves are designed with a rising, non-rotative spindle and a robust bolted joint between the body and cover. Standard spindle threads adhere to ACME2G-LH.
Designed for effortless operation with a handwheel, these gate valves can also be adapted for angle transmission, electric actuator, or pneumatic actuator upon mutual agreement. Larger diameter gate valves are equipped with bearings for smoother control. The sealing material comprises pressed rings from expanded graphite and graphite-plaited rings, meeting the stringent requirements of the Clean Air Act Amendment from 1990. Additionally, these gate valves can be customized with drainage, venting, relief from inter-space, and bypasses, based on special customer requests.
Design Dimension
Standard design dimensions are detailed in the table below.
Material design
The gate valves are available in various material configurations to suit different needs.
Assembly
The yoke gate valve can be installed in any position within the pipeline.
Testing
Our gate valves undergo rigorous pressure tests in accordance with API 598 standards. These tests include strength and tightness evaluations, backseat tightness, closure tightness under low pressure, and, upon request, high-pressure closure tightness.
