Difference Between Gate Valve and Globe Valve
Specialtyvalve is a leading Gate Valve manufacturer in India. A Gate valve controls the flow by lifting and lowering the gate. It is called as a Gate Valve because it allows the flow to be in one direction, which slides into the flow to shutoff therefore acting like a Gate. Whereas a Globe Valve is primarily designed to stop, start and regulate flow using a closure member referred as a disc. Globe valves are most suitable and widely used for throttling and controlling fluid flow; generally employed in small size piping. The disc can be completely removed from the path or can completely close the path of flow.
What is the difference between Gate and Globe Valve?
|Gate Valve||Globe Valve|
|Built is simpler, with majority of parts on top of valve body||Built is complex, major internal components are inside the body cavity|
|High Pressure||High Pressure|
|Is a multidirectional valve||Is unidirectional|
|Offers less resistance to fluid flow||Offers more resistance to fluid flow|
|Comparatively cheaper||Costlier due to a complex design|
Types of Globe Valves:
- Y type Globe Valve
- Angle type Globe Valve
- Forged Steel Globe Valve
- Pressure-seal Globe Valve
- Bellow Seal Globe Valve
Types of Gate Valve:
- Rising Stem Gate Valve
- Non-Rising Stem Gate Valve
- Bellow Seal Gate Valve
- Pressure Seal Gate Valve
- Cryogenic Gate Valve
- Forged Gate Valve
Advantages of Gate and Globe valve:
Gate Valve: It provides a good pressure drop during less operations. It can be used in bi-directional applications, as it also is suitable for high pressure and temperature and requires less maintenance.
Globe Valve: It has a good sealing capacity, and moderate to good throttling capability. Provides a wide range of capabilities as available in TEE, WYE and Angel body styles. Machining and resurfacing of the seats are easy. The globe valve can be used as a stop-check valve by modifying the design slightly.
Applications of Gate Valve:
- Chemical Industry
- Oil & Gas
- Water & Waste Water treatment plants industry
- Petrochemicals Industry
Applications of Globe Valve:
- Cooling water systems requiring flow regulation
- Fuel oil system requiring leak-tightness
- Control valve bypass systems
- High-point vents and low-point drains
- Oil and gas, feed water, chemical feed, refinery, condenser air extraction, and extraction drain systems
- Boiler vents and drains, steam services, main steam vents and drains, and heater drains
- Turbine seals and drains
