Technical bulletin

Series globe-single seated, top guided globe valves are economical high-performance control valves designed to provide the best possible control accuracy and wide rangeability. The trim design is a multi-hole are loacated on the cage wall. The pressure reduces as it passes multi-hole. This gives good resistance to cavitation on high pressure drop applications. Temperature limits -29 ... +260 °C with standard bonnet construction. ASME class 150-600. Many end connection styles available for different applications.
