Brand Innovation Model Z40 (1) H (W) -150 stainless steel flange connection form the main body material nominal diameter 15-300 (mm) Suitable medium water-tight seal in the form of hard-Standard American Standard appearance of large two-way flow direction Drive Manual Parts and accessories hand wheel uses a hydrophobic environment Pressure Operating temperature Room temperature pressure type (channel position) straight-size DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250, DN300, DN350 Stainless steel gate [Advantages: 1, small flow resistance. Body internal media channel is straight, medium into a linear flow, small flow resistance. 2, more effort when opening and closing. In contrast with the shut-off valve, since either open or closed, the shutter movement direction are perpendicular to the flow direction of the medium. 3, height, long opening and closing times. Gate opening and closing stroke of a larger drop is carried out by a screw. 4, easy to produce water hammer phenomenon. The reason is that long off time. 5, the media can flow in any direction to both sides for easy installation. Channel is symmetrical on both sides of the gate valve. 6, the structure length (the distance between two lines between the connecting end of the housing) is small. 7, simple shape, structure, length short, good manufacturing processes for a wide range. 8, compact structure, the valve rigid, channel flow, flow resistance small number, the sealing surface of stainless steel and tungsten carbide, long life, light and flexible operation. [Valve Features]: Light weight: body made of high grade cast iron ball black, lighter in weight than traditional gate about 20% to 30%, easy installation and maintenance. Flat-type brake seat: the traditional gate often through water pipes after foreign objects such as stones, wood, cement, iron, silt and other debris in the valve bottom groove, can not be closed tight and likely to cause the formation of water leakage, resilient seated gate valve at the bottom of the pipe machine uses the same flat design, easy to siltation caused by debris in the fluid moving. Overall package of plastic: gate with high quality rubber within the overall outsourcing glue, Europe's leading rubber vulcanization technology makes the gate after curing to ensure accurate geometry, and rubber and ductile gate then solid, easy to fall off and good elastic memory. Casting Body: Body using precision casting, precise geometry allows the body without any internal finish to ensure that the valve seal.
