Globe Valve Bellow Seal - Fig. 84 | Comeval

The Globe Valve Bellow Seal - Fig. 84 by Comeval is a metal-seated, unidirectional valve designed for stopping flow in various applications, including process, power, and oil & gas industries. It features atmospheric sealing achieved through flexible graphite rings or bellows and can be operated via handwheel, gear, or actuator. The valve's weir body design results in a higher pressure drop compared to gate or ball valves but allows for quicker operation, making it suitable for use as a regulating valve when equipped with a throttling plug. The valve range offers diverse design combinations, including different construction patterns (straight through, angle, Y type), plug designs, sealing options, end connections, materials, and trims. It accommodates nominal sizes from DN10 to DN600 (3/8" to 24") and design pressures from PN16 to 420 (ANSI Class 150 to 2500). Typical applications include HVAC, lubrication, steam, and gases. The valve is certified with Comeval PED Module H, EAC certifications, and ATEX conformity declarations.

Description

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.

Other typical denominations:

Applications: HVAC,lubrication, steam, gases, etc.

Certifications: Comeval ped module h certificate of conformity, Eac certification 032, Eac declaration 010, Eac declaration 032, Globe valves declaration of conformity, Globe valves declaration of conformity atex
