Globe Valves
GL1 Globe Valves Features
Working pressures Class 1500, Class 2500, Class 4500
Working temperature from -20℉ to 1250℉ (-28℃ to 676℃)
One-piece forged body and bonnet, no joints to leak and no welds to cut for servicing
65° Y patterns design reduces pressure drop
One step removal of all working parts for quick and easy maintenance
Non rotating stem design ensures low torque and prevents torsional damage of the packing
The top- and bottom-guided disc assures perfect seat and disc alignment in spite of side thrust caused by high velocity flow. This prevents stem from scoring and galling and provides longer disc seal and body life
Solid Stellite disc, seat ring and backseat provide excellent long service life even in severe services
Precision stem and packing chambers to 8 RMS finish
Fully enclosed, lubricated stem drive system with needle bearings ensures low operating torque
Rugged and knobbed handwheel make sure the grip when wearing gloves

GL2 Globe Valves Features
Three Bonnet designs: Bolted Bonnet, Outside Screw and Yoke (OS & Y)
Stronger, leakproof body-bonnet joint fully encased spiral wound gasket
The top- and bottom-guided disc assures perfect seat and disc alignment in spite of side thrust caused by high velocity flow. This prevents stem from scoring and galling and provides longer disc seal and body life.
Large clearance between stem and disc allows disc to move freely.
Precision stem and packing chambers, Packing rings individually pre-stressed for tight seal
Two-piece self-aligning gland.
