Product Description

Product Description

API Cast Steel Flanged Globe Valve 150LB~2500LB WCB/CF8/CF8M/WC6/WC9, DN40~DN900 Handwheel/Gearbox,BS1873
Globe valves are primarily used as control valves where throttling or both throttling and shut-off are required. Globe Valves can also be used for on-off service; however, because of design, a pressure drop becomes inherent. This is generally confined to on-off applications where the valve is normally closed and pressure drop is not important when the valve is open. Globe valves are uni-directional valves and normal applications will find the globe valve with the flow and pressure under the disc. GLT cast steel globe valves are commonly made in outside screw and yoke designs with full ports and heavy-duty type discs.

 

Manufacturing Standards

General Design	API600/BS1873
	API602
Pressure Rating	ASME /ANSI B16.34
Face to face	ASME/ANSI B16.10
Flange Dimensions	ASME/ANSI B16.5
Butt-weld end	ASME/ANSI B16.25
Inspection and Test	API 6D/API598

Body and Bonnet ConnectionStandard body-bonnet joints of globe valves are connected by studs and nuts and are machined as follows:

PRESSURE CLASS	JOINT DESIGN	GASKET TYPE
150 & 300	Male-female	Spiral wound metal with Graphite
600	Male-female/Ring type joint	Spiral wound/Ring joint metal
900 & above	Ring type joint	Ring joint metal

Disc
The valve is normally supplied with the conical plug type disc. The disc rotates freely on the stem and incorporates a differential angle from that on the seat ring. This design provides the maximum assurance of shut off, is less likely to stick in the body seat, and is considered the simplest design for field repair.

Seat Ring
The seat ring design, normally supplied is as follows:

PRESSURE CLASS	SEAT DESIGN
150	2''-8'' Integral
	≥10'' Seal Welded
300 & Above	2''-6'' Integral
	≥ 8'' Seal Welded

Other design are available for request. 
Stem
All stem are rotating, rising and designed with integral backseat features which provide an ultimate seal during packing changes.
Packing
The stem packing is designed and arranged to ensure a maximum seal along the stem during operation or while at position, thus allowing for a greater reduction in fugitive emissions. Our packings are made of Graphite(Non-asbestos).
End Connections
Our standard end connection produce valves with:- Flange end type with Raised Face(RF), Flat Face(FF) or Ring Type Joint(RTJ) that conform to ANSI B16.5.- Butt-welding ends(BW) that conform to ANSI B16.25.- Threaded ends(NPT) that conform to ANSI B1.20.1, socket weld ends that conform to NASI B16.11.- All face to face /end to end dimensions conform to ANSI B16.10Other special end connections are supplied according to customer's requirements
