It is suitable for non-corrosive liquids, gases, and steam. Before the valve in the system pipeline (when the pressure before the valve increases , the control valve opens) or after the valve (when the valve pressure rises, the control valve opens) pressure control. Widely used in petroleum, chemical industry, electric power, metallurgy, medicine, food, textile, machinery, HVAC. The action types include pressure regulation after the pressure reducing valve (B type) and pressure regulation before the pressure relief valve (K type).<\/p>\n<p>&nbsp;<\/p>\n<p>Features of self-operated pressure control valve:<\/p>\n<p>&nbsp;<\/p>\n<p>Compared with the manual control valve, the self-operated pressure control valve has the advantage that it can be adjusted automatically; compared with the electric control valve, its advantage is that it does not require external power. The self-operated control valve relies on the pressure and temperature of the medium flowing through the valve itself as an energy source to drive the valve to work automatically, and does not require an external power supply and secondary instruments.<\/p>\n<p>&nbsp;<\/p>\n<p>Self-operated pressure control valve function:<\/p>\n<p>&nbsp;<\/p>\n<p>All self-operated control valves use the feedback signal (pressure, differential pressure, temperature) at the valve output to transmit to the actuator through the signal pipe to drive the valve disc to change the opening of the valve to achieve the purpose of control pressure, flow and temperature. , In the closed water circulation system (such as hot water heating system, air conditioning chilled water system), the correct use of this valve can easily realize the flow distribution of the system; it can realize the dynamic balance of the system; it can greatly simplify the debugging work of the system ; Can stabilize the working state of the pump, etc.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>Parameters of self-operated pressure control valve:<\/p>\n<table>\n<colgroup>\n<col width=\"128px\" \/>\n<col width=\"678px\"
