Globe Valves than Gate Valves are simple, manufacture and service are more convenient.
(2) seal face not easy wear and tear of bruises, good sealing, open the disc and body when there was no relative sliding between the sealing surface, and wear and bruises are not serious, sealed performance is good, long service life.
(3) when opening and closing, the valve stroke is small, so stop valve height than gate valves is small, but structure length than gate valves long.
(4) opening and closing torque, opening and closing is arduous, opening and closing time the headmaster. 
(5) fluid resistance is great, because the body within the medium channel more twists and turns, fluid resistance, power consumption.
(6) medium flow direction PN nominal pressure than 16 MPa, generally USES the downstream, and media from the disc direction under high; PN nominal pressure quartile 20 MPa, generally USES the current, and media from the disc direction gross. To increase seal can. When using, stop valve medium can only single direction, can
