MT Group Gate Valve – 6" Class 150 RF, Bolted Bonnet, WCB Body, A182 F6a Stem

The MT Group 6-inch Class 150 gate valve is a robust shutoff valve engineered for efficient flow isolation in industrial pipelines. Constructed with a high-strength A216 WCB carbon steel body and featuring raised face flanged ends, this valve incorporates a bolted bonnet and a flexible wedge disc design. The disc is fabricated from WCB and hard-faced with 13% chromium (13Cr) for enhanced durability and corrosion resistance. The seat ring is made from A105N carbon steel with a Stellite 6 overlay to withstand high wear and provide a reliable sealing surface. An A182 F6a stem offers excellent mechanical strength and corrosion protection, ensuring smooth operation and long-term reliability. This valve is well-suited for use in water, oil, steam, and general-purpose service pipelines in the energy, chemical, and industrial sectors.
