This series valve is the company with reference to foreign advanced products and successfully developed a new type of pilot-large diaphragm valves, the product on the basis of common valve made a lot of improvement. Diaphragm using a new material, and greatly processing work area, so the pressure upstream or downstream load valve subtle changes can be timely and accurate feedback to the main valve diaphragm, to adjust the opening of the main valve to ensure the stability of the downstream pressure. Another prominent feature of the permanent 嘉斯派莎克 steam valve is: can be installed on the same body and multiple interchangeable pilot valve in the regulator, while achieving temperature control, control the upstream pressure, remote control switch Wing 嘉斯派沙克 steam valve and other forms of flanged connections: When RF FM RJ large diaphragm pilot valve factory with high sensitivity, adjust the spring in an uncompressed state, when the main valve and the valve is in the pay closed state, the use of the adjustment screw is rotated clockwise, the compression adjusting spring, the diaphragm valve down to open the top pay, the medium by a hole into the top of the piston, under the effect of medium pressure, pushing the main valve downward movement After leaving the main valve seat, the media flow valve, while the c hole into the bottom of the diaphragm, the valve when the pressure exceeds the set pressure, adjust compression springs push the diaphragm moves. pay the valve moves in the closing direction, medium flowing above the piston decreases, resulting in reduced pressure, then the main valve shift in driving the main valve spring force on the main valve of the gap with the main seat of the reduced medium flow be reduced the valve after the pressure fall to a new equilibrium, whereas when the valve pressure is below the set pressure, the main valve and main valve seat gap increases, the media flow increases, the pressure will be increased so that the valve reaches new balance.
