Product Name: Stainless steel threaded vertical check valve Model: H12W-16P pressure: 1.6MPA, 2.5MPA, 4.0MPA Material: WCB, 304,304L, 316,316L Working temperature: -20 ~ 232 ℃ Suitable medium: water, oil, gas or other corrosive liquids (W.O.G) Thread Standard: NPT, BSPT, BSP, DIN259 / 2999, also known as a one-way check valve or check valve, whose role is to automatically prevent fluid backflow valve . Check the valve to open under the pressure of the fluid, the fluid flows from the inlet side of the outlet side. When the inlet side of the pressure lower than the export side, the valve in fluid pressure factors, such as gravity itself automatically close to prevent backflow of fluid. Opening and closing pieces by medium flow and strength to turn itself on or off, in order to prevent the media called backflow check valve. Check valves are automatic valves, mainly used for one-way flow of media channels, only allowing media to flow in one direction, in order to prevent accidents. Check valve according to the structure can be divided into lift check valve, swing check valve and butterfly valve three. Lift check valve can be divided into vertical and horizontal. Swing check into a single lobe, double valve type and Orange Peel three. Butterfly valve for straight-through, check the connection over several forms can be divided into threaded, flanged and welded three. Stainless steel threaded vertical valve installation should note the following top: 1, so that the check valve in the pipeline do not bear the weight of a large valve: the impact should be self-supporting, so that the pressure generated from piping 2 Note the direction of flow of the medium should be consistent with the direction of the arrow when the body of the standard installation. 3, the vertical lift check valve should be installed in a vertical pipe. 4. Do not make the check valve in the pipeline bear the weight of a large check valve should be self-supporting, so that the impact of unmanaged system pressure. 5, note the direction of flow of the medium should be consistent with the direction of the arrow on the body when installing ticket. 6, vertical lift check valve should be installed in a vertical pipe. 7. The level of valve lift check valve should be installed in horizontal pipelines. Vertical stainless steel threaded valve is widely used in water treatment equipment, chemical equipment, petrochemical equipment, oil equipment, paper making equipment, mining equipment, power equipment package, gas equipment, food equipment, pharmaceutical equipment, water supply and drainage facilities, municipal valves machinery and equipment valves, electronic industrial valves, construction of valves, industrial pipeline valves, common parts, industrial equipment, fire HVAC, central air conditioning, filtration equipment, environmental equipment and other fields.
