The stem axis of J41W stainless steel flange globe valve is perpendicular to the sealing surface of the valve seat.The valve stem has a relatively short opening or closing stroke and a very reliable cutting action,making it very suitable for use as a medium for cutting,adjusting,and throttling.
Characteristics of Stainless Steel Globe Valve Products
(1)The structure is simpler than gate valves,making manufacturing and maintenance more convenient.
(2)The sealing surface is not easily worn or scratched,with good sealing performance.There is no relative sliding between the valve disc and the valve body sealing surface during opening and closing,so the wear and scratches are not severe,the sealing performance is good,and the service life is long.
(3)When opening and closing,the valve disc stroke is small,so the height of the globe valve is smaller than that of the gate valve,but the structural length is longer than that of the gate valve.
(4)The opening and closing torque is large,the opening and closing are laborious,and the opening and closing time is long.
(5)The fluid resistance is high due to the tortuous medium channels inside the valve body,resulting in high fluid resistance and high power consumption.
(6)When the nominal pressure PN of the medium flow direction is≤16MPa,it is generally used to flow downstream,and the medium flows upward from below the valve disc;When the nominal pressure PN is≥20MPa,reverse flow is generally used,and the medium flows downwards from the valve disc to increase the sealing energy.When in use,the medium of the shut-off valve can only flow in one direction and cannot change the flow direction.
(7)The valve disc is often eroded when fully open.
