What is Globe Valve?
The Globe Valve is widely used and suitable for On / Off or
Regulating fluid flow. Main single seating in globe valves is
parallel to line of flow and the flow pattern is offset type,
not a straight line through flow as gate valve or ball valve.
This design affords a better closure than a gate valve. The
change in direction of fluid flow produces increased resistance
and considerable pressure drop. Because the flow is directed
against the disc in a symmetrical fashion, there is very little
wear on the valve parts and is one of the easiest valves to
repair.
Globe Valve can be Bolted Bonnet construction or Union
Bonnet Types. Bolted bonnet Globe Valves are very easy to
maintenanace. Valve seat can be intergal or replaceable as
per application suit. 3 Way Globe also an option for Mixing
& Diverting application operated by manual, pneumatic or
electrical.
Globe valves are also available with range of operation such as
Manual Hand Wheel operated / Gear operated / Pneumatic Diaphragm
Actuator operated / Pneumatic Cylinder Actuator Operated /
Electrical Actuator operated / Motorized Actuator Operated.
Globe Valve also can supplied with wide range of Disc such as
Plug Type Disc, Flat Disc, Regulating Disc, Soft Seated Disc,
Guided Disc etc to suit various application. Dharmi Engineers
manufacturing & exporting wide range of Industrial Globe
Valve. Dharmi Engineers also offer Three Way Globe Valve (Mixing
& Diverting Type Globe Valve) for various industrial
applications.
What is Rising Stem?
Outside
Screw & Yoke (OS & Y) design keeps the stem threads
outside the valve and is recommended where high temperatures,
corrosives, and solids in the line might damage the stem
threads inside the valve. When Globe Valve will open, the stem
extends with hand wheel indicates the position of valve
opening.
What is Valve Trim?
A
trim means internal working parts of valves. In Globe Valves the
Stem (Spindle), Seat Ring, Disc, Disc Nut, Back Seat Bush, Gland
Bush is trim.
What is Integral Seat?
These
types seats are integral with body casting. Machined into the
body casting.
What is Renewable Seat?
Separate
Seat Rings that screw into the valve body, which is called as
Renewable Seats. ____________________________________________________________________________________________________________

Dharmi Engineers Globe Valves are Outside Screw, Rising Stem, Bolted Bonnet Construction, threads are away from the line fluid and easy to lubricate.
Dharmi Globe Valves are generally available with Plug Type Disc, which is designed to give leak tight seating over a long period of in built wear life. Dharmi Globe valves body seat ring is shoulder type, threaded body seat ring which has large taper area that is for ample seating. Two nos. slots are provided on body seat ring, which is for easy removal for servicing at site. Welded type seat ring & Integral seat ring are also available in Dharmi Globe Valve. All Globe Valve stem is made from solid one piece construction. The yoke bush of Globe Valve has a long thread engagement for accurate stem alignment. The standard range of Dharmi Globe Valve is sizes of up to 12 (300mm).
