The Usmani valves Co Pvt Ltd UTVC Make Globe Valves are primary used to modulate or regulate the volume of the flow, a Globe Valve is not recommended when a continuous full flow of fluid is required due to the high pressure drop inherent to the design of a Globe Valve. The disc of globe valve can be plug type, needle type or parabolic type, globe valves are on/off valves, but sometimes they are utilized in throttling service, globe valves are widely used for the medium of water, steam, oil, & Gas , Sugar industries, Power plant, Textile Mills, product, nitric acid, acetic acid, oxygenation, etc.
Forged Steel Globe Valve Flanged ANSI 150
Flanged ANSI 150 RF, A105N Forged Steel Body & Bonnet, Outside Screw & Yoke, Plug Type Disc, Rising Hand wheel Operated, Design to API 602 Rated CL150. Note: Temperature details are available on our Data Sheet
These special blow off valves are available in bolted bonnet angle and streamlined flow 45º inclined designs for Class 600 and 1500 primary service and in bonnet less angle and inclined designs for Class 2500. Stellite 6 seats and fully-guided Stellite 6 discs resist the excessive corrosion and erosion effects aggravated by grid and boiler scale particles and high temperature changes. Designed for quick and easy maintenance – one step removal of all working parts including packing.
All pressure containing parts within one body-bonnet forging – no joints to leak or welds to cut for servicing.
Non rotating stem allows a non-spinning disc, ensures low torque and prevents torsional damage of the packing. Fully enclosed, lubricated stem drive system with needle bearings ensures low operating torque.
Solid Stellite disc, seat ring and backseat provide excellent long service life even in severe services.
Backseat bevel on the stem, not on the disc, satisfies both API-600 and API-602 specifications.

Usmani Valve Forged Globe Valves are linear motion valves devised for stopping the flow of the service fluid when necessary. They are of robust and compact design, bolted bonnet, outside screw and yoke, conventional port and rising hand wheel, being the closure element a disc seating against a precisely machined seat thus achieving the positive closure. The atmospheric sealing is achieved by flexible graphite rings. The flow comes upwards underneath the seat, being unidirectional. Their shape leads to higher pressure drop compared to gate valves but operation is quicker and this feature allows to use the valve as regulating valve when arranged with throttling plug. Valves are of easy and safe operation being widely used in power, chemical and oil industry. The range is also comprehensive of a wide offer of different versions and options. The standard operation is achieved by hand wheel,

Globe & Regulating ValveSpring action yoke arms compensate for effect of temperature changes, assuring positive seating.Heat treated stainless steel stem is corrosion and galling resistant, suitable for service over 1000°F. Stake Locked Disc Nut - Positive locking prevents unscrewing.Disc pad, H-25 Alloy prevents stem galling. No damage from acid washing.Rugged integral hard facing (Stellite or equal), allows repeated refinishing. Long life, high tensile aluminium bronze bushing.Rugged ball joint flange, no gland misalignment.Packing gland is stainless steel split for easy removal during repacking. Deep stuffing box. Packing is corrosion inhibited, preventing stem pitting. Body and bonnet have a full penetration weld without crevices preventing corrosion and providing a unitary construction. No weld cutting required for servicing. Body cavity has ample clearance between body and disc, allowing adequate flow passage, preventing side thrust and reducing wear on stem guide.
Usmani valves Globe valves are used mainly for steam or other media where a throttling service is required. The seat design gives an advantage for doing this by utilising its globe shape as it comes down to connect with the seat effectively cutting the flow gradually up until it seals completely on the seat face. This however does cause a larger pressure drop than say a gate valve and causes turbulence in the line. The size, pressure class and material selection of all globe valves are the responsibility of the user or system designer. Process Systems may offer suggestions in this area, however the selection process is solely the responsibility of the end user or plant operator.
Globe valves are unidirectional whereby they are only designed to take the flow in one direction, under the disc. There is an arrow of direction cast into the valve body but can easily be checked by looking into one end of the valve and see whether you are looking at the underside of the seat or above the seat. It is recommended that the valve be mounted vertically only whereby the hand wheel operation will be at the top of the valve. This ensures that no premature wear or damage will occur to the valve.
