Body
• Lubi Globe Valve Body is designed in such a way that the flow passage area never decreases. This ensures & helps in achieving proper flow with minimal loss at the outlet of the valve.
• The Body has three internal guide ribs which help in guiding the plug vertically which helps in proper plug seating & providing tight leak proof seal.

 

Bonnet​
• The Bonnet of Gate Valve are designed in such a way that Integral Back-Seat as well as Threaded Back-Seat options are available to offer as per customer requirement.
• The Bonnet also houses the Yoke Sleeve & Stuffing Box assembly both of which are precisely machined to give proper alignment to the stem & the wedge during sealing.

 

​​Body / Bonnet Joint​
• The Body-Bonnet Joint Gasket is made up of Graphite reinforced by SS Ring so that it can handle high pressure & prevent any leakage pass through it.
• The Body – Bonnet Joint is tightly sealed with the help of standard Studs & Nuts as per the Bolting Calculation to prevent any leakage past the joint under maximum operating pressure for which the valve is designed for.

​

​​Plug​
• Lubi Globe Valve Plug is casted in one piece. The plug is properly guided inside the body with the help of three Guide Ribs provided in the body
• The plug is able to rotate freely inside the body which helps in the plug getting properly seated & aligned with the Body Seat & hence provide leak proof seal.
• There is a provision of providing a Thrust Plate inside the plug in between the face of stem & plug ID which makes sure that the stem as well as plug do not wear out but the small inexpensive Thrust Plate wears out due to friction. • • • • Once the Thrust Plate wears out it can easily be replaced.

 

​​Seat Ring
• Lubi Globe Valves come with a seal welded Seat Ring which offer tight leakproof seal without any deformation or loosening at high pressure – temperatures compared to threaded seats. Also, the chance of leakage past the Body & Seat gets eliminated with seal welded seats.
• For Stainless Steel MOC’s we also offer integral Seats which are integral with the Body Casting & are machined to behave as Seats for providing sealing.
• Threaded Seats are available optionally as per customer requirement for Lubi Globe Valves.

​

​​Stem​
• Lubi Globe Valve has a Stem which is of one piece construction.
• It has smooth machined surface & ACME Threads made using precision machinery & tooling in order to increase life of the stem as well as to minimize leakage, friction & thus torque.
• Lubi Globe Valves have a stem which is secured to the Plug using a stem nut which allows free rotational movement of the plug while opening & closing. This ensures uniform seating when the valve is closed & hence prevents any leakage.

 

​​Yoke Bush​
• It is made up of either Cast Ductile Iron Grade D2 or Aluminum Bronze material in order to provide corrosion resistance, heat resistance & prevent & wear.
• It has long thread engagement as per Standard API 600 which provide proper alignment of the stem.
​

Stem Packing Box​
• The Packing Box contains space for stem packing & is machined as per the precise tolerances given by Design. The surface finish is also closely controlled in order to prevent any leakage of steam / fluid past through it.
• Seven numbers of Gland Packing are provided in the Stem Packing Box. The two ends of the packing are of Graphite cross-plaited packing & the middle 5 are of compressed graphite packing rings.
