Stainless steel screw gate within Z15W

Stainless steel screw gate valve Shanghai Valve Manufacturing Co. crown ring, the inner stainless steel screw gate Z15W 1, nominal pressure: 2.5MPa 2, temperature range: -20 ~ 232 ℃ ~ 350 ℃ 3, Suitable medium: water, oil, gas and some corrosive liquid (WOG) 4, thread type: G.NPT.BSPT.BSP.DIN259 / 2999 Pros: small flow resistance. Body internal media channel is straight, medium flows in a straight line, small flow resistance. More effort when opening and closing. In contrast with the shut-off valve, because both the open or closed, the shutter movement direction are perpendicular to the flow direction of the medium. Height, long opening and closing times. The shutter opening and closing stroke larger drop is carried by the screw. Easy to produce water hammer phenomenon. The reason may be a long off time. Medium can flow in any direction to the sides, easy to install. Both sides of the valve channel is symmetrical. Structural length (the distance between two connection lines between the end face of the housing) is small. A simple shape, structure, length short, good manufacturing processes, a wide range. Compact, valve rigid, channel flow, flow resistance small number, the sealing surface of stainless steel and tungsten carbide, long life, the use of PTFE packing. Reliable sealing. Lightweight and flexible operation.
