The V8000 Series Control Valve is a globe-type regulating valve designed for precise flow control in steam and thermal fluid systems, including heat transfer oil. It features a straight-through globe valve design and can be equipped with either pneumatic or electric actuators, offering fail-close (FC), fail-open (FO), or fail-locked (FL) actions for pneumatic types. The valve is available in various configurations, including standard, bellows-sealed, balanced single-seat, and balanced double-seat, to meet diverse industrial process control requirements. Body materials include WCB, WC5, WC6, WC9, CF8, CF8M, and CF3/CF3M. It supports a wide temperature range from -250°C to +530°C with an extended bonnet option. Available in body sizes DN15–DN300, it accommodates pressure ratings of PN25 and Class150, with end connections such as flange (RF), screwed (FM), butt-weld (BW), and socket-weld (RC).
