Metal seated globe valves, unidirectional, for stopping the flow in process, power and oil&gas applications. The atmospheric sealing is achieved by flexible graphite rings or by bellows. Operated by handwheel, gear or actuator. Weir body leads to higher pressure drop compared to gate or ball valves but operation is quicker and this feature allows to use the valve as regulating valve when arranged with throttling plug.
Specification of the range:
Diverse design combinations by pattern of construction (straight through, angle, Y type), plug designs (marginal, regulating, non-return, balancing, V-port, stellited, soft seal), bellows seal and secondary sealing designs, end connections (flanged, BW, SW, threads), materials of construction (cast and forged) and trims, nominal size range (DN10-DN600 / 3/8-24"), design pressure range (PN16-420 / ANSI Class 150-2500), as well as operation style and accessories.
