Comparison of 2507 Dual phase Steel Gate Valve and Globe Valve Technologies
1. Comparison of core parameters
Parameter 2507 gate valve 2507 globe valve
Structural form: open stem/concealed stem, wedge or parallel gate lifting valve disc (conical sealing surface)
When the flow resistance characteristic is fully open, the flow resistance is extremely small (approximately straight through), and the flow resistance is relatively large (the medium needs to bypass the valve disc)
Sealing performance: Hard sealing (metal to metal) or soft sealing. Hard sealing is mainly used, with some soft sealing designs
Applicable pressure PN1.6~42.0MPa (American standard Class 150~2500) PN1.6~32.0MPa (conventional PN1.6~16.0MPa)
Applicable temperature -29 ℃~+550 ℃ (special design required for high temperature) -29 ℃~+250 ℃ (soft seal type limited to 120 ℃)
The main driving modes are manual, electric, and pneumatic manual, with some electric adjustment types
