Type 1711 Severe Service Control Valve

The U.S. Type 1711 globe control valve is designed for modulating flow or pressure control in industrial and research applications at
temperatures of 850° F (454° C) or less (400° F, 204° C) maximum for TFE chevron packing and standard bonnet). The unit features
an oversized stem and an extra heavy guided inner valve for added strength and longevity. The stem packing is designed for tight
sealing, long life, and quick, easy maintenance. The union bonnet with a graphite gasket provides excellent sealing without having bonnet threads in contact with the process fluid. The multi-spring, 35-square-inch, diaphragm actuator can be either ATO or ATC
action. Maximum corrosion protection on all non-stainless actuator components is standard. The spring preload is fully adjustable.
