JOEPAI high quality Butt Welded Gate Valve, The integrated welding connection and full bore high reliability sealing structure are particularly suitable for conveying systems that require tight, zero leakage, stable pressure resistance. This product meets international standards and has the properties of stability, ductility, and long lifespan.
1. Low flow resistance. The internal medium channel of the valve body is
straight through, and the medium flows in a straight line with low flow
resistance.
2. Butt Welded Gate Valve is more effortless to open and close. Compared to globe valves, the
direction of gate movement is perpendicular to the direction of medium flow,
whether it is open or closed.
3. High height, long opening and closing time. The opening and closing
stroke of the gate is relatively large, and the lifting is carried out
through screws.
4. Water hammer phenomenon is not easy to occur. The reason is that the
shutdown time is long.
5. The medium can flow in any direction on both sides, making it easy to
install. The two sides of the gate valve channel are symmetrical.
6. The structural length (the distance between the two connecting end faces
of the shell) is relatively small.
7. Simple form, short structural length, good manufacturing processability,
and wide applicability.
8. Compact structure, good valve rigidity, smooth channel, low flow
resistance, sealing surface made of stainless steel and hard alloy, long
service life, PTFE packing, reliable sealing, easy and flexible operation.
