Carbon Steel Gate Valve
A carbon steel gate valve is a carbon steel body shutoff valve with a wedge-shaped disc that moves vertically within the body to fully open or fully close the line for high pressure and high temperature service. When fully open, the flow path is unobstructed, resulting in very low pressure loss.
For larger sizes, API 600 standard ASTM A216 WCB cast steel Class 150 flanged (2″–16″) and ASTM A217 WC6 alloy cast steel Class 600 butt-weld (2″–12″) models are available; for smaller sizes, API 602 standard ASTM A105N forged steel Class 800 and ASTM A182 F22 alloy forged steel Class 1500 socket-weld (1/2″–2″) models are available. Seat surfaces are hardened with Stellite 6.
