| GLOBE
VALVES |
 |
Globe Valves
(Cast Steel) are tight sealing, easy operation, regulation valves for liquid
and gaseous fluids over a wide range of line pressures and temperatures.
|
| Globe valves
are of Outside Screw & Yoke and with Bolted Bonnet Construction. The
Outside Screw ensures easy lubrication and prevents corrosion and erosion
by line fluids.
|
| The body
is designed for strength to meet the operating conditions. The bonnet is
fitted with a bonnet bush to guide the stem and provide for back seating
when the valve is open and under pressure. |
| The disc
provides a fine bearing on a taper seat for tight sealing over a wide range
of differential pressures. As the seating between disc and body seat ring
is a narrow line contact, tight sealing can be achieved even if any foreign
particle gets stuck to the seating area. The disc and stem are held together
by a disc nut with allowance for disc to swivel. The disc nut is tack welded
to prevent loosening in service and has slots for easy removal while servicing.
The seating surfaces are ground and lapped. |
| The stuffing
box with a high quality surface finish holds a minimum of 6 packing rings
to enhance gland tightness and extend the life of packing rings. |
| A two-piece
ball type gland arrangement minimizes stem scoring and binding. It also
ensures uniform load on packing even when the gland bolts are not uniformly
tightened. |
| Valves
are offered with flange and but weld ends |
| Flanged
- ASME / ANSI B 16.5 Raised Face (RF) finish to 125 to 250 Ra (AARH) |
| Butt weld
- ASME / ANSI B 16.25 to suit the corresponding pipe schedule. |
