Technical description
Metal-seated, non-return globe valves for shutting off flow in industrial, energy and oil and gas applications. Atmospheric sealing is achieved by means of flexible graphite rings or bellows. They are operated by a handwheel, gear or actuator. The weir-shaped body results in a greater pressure drop compared to gate or ball valves, but operation is faster and this feature allows the valve to be used as a control valve when combined with a throttling plug.
Range specifications:
Various design combinations depending on the construction pattern (straight-through, angle, Y-type), plug designs (marginal, regulating, non-return, balanced, V-port, stellited, soft-seated), bellows sealing and secondary sealing designs, end connections (flanged, BW, SW, threaded), materials of construction (cast and forged) and internal components, nominal diameter range (DN10–DN500 / 3/8–2″), design pressure range (PN16–420 / ANSI Class 150–2500), as well as actuator type and accessories.
