  • Ordering Process

The stem axis of the J41W stainless steel flange valve is perpendicular to the sealing surface of the valve seat. Stem opening or closing stroke is relatively short, and has a very reliable cut-off action, making this valve is very suitable for medium cut-off or adjustment and throttling use.


Features of stainless steel globe valves


(1) the structure is simpler than the gate valve, and it is more convenient to manufacture and maintain.


(2) Sealing surface is not easy to wear and scratch, good sealing, no relative sliding between disc and valve body sealing surface when opening and closing, so wear and scratch are not serious, sealing performance is good, long service life.


(3) when the valve is opened and closed, the valve stroke is small, so the height of the cut-off valve is smaller than that of the gate valve, but the length of the valve is longer than that of the gate valve.


(4) the opening and closing moment is large, the opening and closing is more laborious, and the opening and closing time is the headmaster.


(5) fluid resistance is large, because the medium channel of the valve body is tortuous, the fluid resistance is large, and the power consumption is large.


(6) When the nominal pressure PN is less than 16 MPa, the medium flows downstream from the bottom of the valve disc; when the nominal pressure PN is more than 20 MPa, the medium flows downstream from the top of the valve disc to increase the seal energy. When used, the medium of the shut-off valve can only flow in one direction, and the flow direction can not be changed.


(7) the disc is always eroded at full opening.


Design and manufacturing standards


1, design and manufacture according to GB12235-89


2, the length of the structure is GB12221-89


3, flange size according to JB/G79-94


4. Valve check and test according to GB13927
