High-pressure valve profile

High-pressure valve is the use of control valve body opening and closing pieces of the opening to regulate the flow of media, the media pressure is reduced at the same time with the role of the pressure valve to adjust the opening and closing pieces of the opening, the valve to maintain a certain pressure Within the scope of the continuous change in the pressure of imports, to maintain export pressure within the set range, to protect the subsequent life of production equipment. High pressure valve is an essential part of the pneumatic control valve, the main role is to depressurize the pressure of the gas source and stabilized to a fixed value, so that the control valve can obtain a stable pneumatic power for regulation and control. According to the structure of the form can be divided into diaphragm, spring diaphragm, piston, lever and bellows; according to the number of seats can be single-seat and two-seat; according to the valve position can be divided into positive action And the reaction type. High-pressure valve work by the valve pressure control. When the pressure sensor detects the valve pressure indication increases, the valve opening of the pressure reducing valve decreases; when the pressure reducing valve is detected to reduce the pressure reducing valve valve opening increases to meet the control requirements. High Pressure Regulator - The valve must have a decompression ratio that is somewhat above the system value; it should be able to respond to positive or negative control signals even at maximum or minimum flow. These valves should be selected for a useful control range, ie 20% to 80% of the maximum flow rate. Normal for the same type or has the same ratio. These types of valves have their own optimal flow characteristics and flow rates required for proportional control. Search Keyword: More Valve Technical Articles
