Globe Valves
An important use of GLOBE VALVE is to regulate or throttle fluid flow none to full capacity. They may be operated efficiently with the stem in any position from wide open to fully closed. The changed in direction of fluid flow through the valve produces increased resistance & considerable pressure drop in globe valves.
SERVICE RECOMMENDATIONS
• Flow regulation or throttling
• Frequent operation
• Increased flow resistance
• Positive shut-off when closed

DISCS/PLUG
Discs & seats in GLOBE VALVE can be repaired or replaced without removing the valve body from the line. The selection of the most suitable discs/seats design is the key to good performance in throttling service FOLLOWING types of Discs are available in “SCENT” GLOBE valves
• Teflon of composition discs
• Fullway or spherical type disc
• Plug type disc
• Needle type disc
