Cylindrical Johnson Screen is a wedge shaped wire welding filter element for solid-liquid separation. Cylindrical screen is a kind of Johnson screen and can be made into different shapes (Basket Shaped Johnson Screen, Nozzle Cap , Tubal Johnson Screen and Conical Johnson Screen and so on). Its filtration mode is filtering from the outside to the inside and filtering from the inside to the outside.
The minimum slot opening cylindrical Johnson screen is 25 um (0.001 inch) and the maximum slot opening cylindrical Johnson screen is 25 millimeter (1 inch).
The common material is 304, 321, 316 L, 904 L duplex stainless steel 2205, duplex stainless steel 2507, Monel alloy.etc.
It is widely used in many fields, such as petroleum refining and refining industry, water supply and sewage treatment, pulp and paper industry, mining and sand processing, construction industry, food filtration, nuclear power and so on.

200P pressure reducing valve details
200P pressure reducing valve details: 200P pressure reducing valve consists of two parts of the main valve and pilot valve. 200P pressure reducing valve The main valve is mainly composed of valve seat, main valve disc, piston, cylinder liner, spring and other components. 200P direct-acting diaphragm-type pressure reducing valve pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. By adjusting the spring pressure to set the outlet pressure, the use of diaphragm sensing outlet pressure changes, through the pilot valve opening and closing drive piston to adjust the size of the main valve throttle flow area, to achieve decompression regulator function. 200P Pressure reducing valve Main technical parameters and performance indicators Nominal pressure (Mpa) 1.0 1.6 Shell test pressure (Mpa) * 1.5 2.4 Seal test pressure (Mpa) 1.0 1.6 The maximum inlet pressure (Mpa) 1.0 1.6 The outlet pressure range (Mpa) 0.09 -0.8 0.1-1.2 Pressure characteristic deviation (Mpa) △ P2P GB12246-1989 Flow characteristics deviation (Mpa) △ P2G GB12246-1989 Leakage 0 Operating temperature 0 ℃ -80 ℃ *.
