{"product_id":"self-operated-pressure-regulating-valve","title":"Self-Operated Pressure Regulating Valve","description":"The Self-Operated Pressure Regulating Valve is an automatic pressure control valve designed to maintain a stable and preset pressure in industrial piping systems. It operates using the energy of the process medium itself, eliminating the need for an external power supply or pneumatic control signal.\n\nThe valve automatically senses changes in upstream or downstream pressure and adjusts the valve opening accordingly. This self-regulating operation provides reliable pressure control, stable system performance, and continuous automatic regulation.\n\nFeaturing a compact structure, simple operation, reliable performance, and easy maintenance, the self-operated pressure regulating valve is an ideal solution for industrial pressure control applications. The pressure setting can be easily adjusted according to actual operating requirements.\n\nKey Features\nSelf-operated design with no external power required\nAutomatic and continuous pressure regulation\nStable and accurate pressure control\nCompact and robust valve construction\nEasy pressure setting and adjustment\nReliable sealing performance\nLow operating and maintenance costs\nLong service life\nSuitable for continuous industrial operation\nAvailable in various sizes, materials, and pressure ratings\nWorking Principle\n\nThe valve uses the pressure of the process medium as the operating energy. The controlled pressure is transmitted to the sensing diaphragm through the sensing system. Changes in pressure cause the diaphragm to move against the preset spring force, which in turn moves the valve plug.\n\nWhen the controlled pressure increases above the set value, the valve gradually closes to reduce the flow rate and lower the pressure. When the controlled pressure decreases below the set value, the valve opens to increase the flow rate and restore the pressure.\n\nThis automatic balancing process enables the valve to maintain the required pressure without external electrical or pneumatic control.\n\nApplications\n\nThe Self-Operated Pressure Regulating Valve is widely used for automatic pressure regulation of:\n\nSteam\nWater\nAir\nNatural Gas\nIndustrial Gas\nOil\nThermal Fluids\nOther compatible industrial process media\n\nTypical applications include:\n\nChemical Processing, Petrochemical Plants, Oil \u0026amp; Gas, Power Generation, Steam Systems, Heating Systems, HVAC, Water Treatment, Industrial Process Pipelines, and General Automation Systems.\n\nProduct Advantages\n\nCompared with externally powered pressure control systems, the self-operated pressure regulating valve offers a simple and economical solution for automatic pressure control. Its independent operating principle reduces system complexity and eliminates the need for additional electrical or pneumatic control equipment.\n\nThe valve can be customized with different valve body materials, nominal sizes, pressure ratings, connection types, pressure setting ranges, and internal trims to meet specific application requirements.\n\nTechnical Highlights\nProduct Type: Self-Operated Pressure Regulating Valve\nControl Mode: Automatic Pressure Regulation\nOperating Principle: Self-Operated\nExternal Power: Not Required\nControl Medium: Process Medium\nValve Type: Globe-Type \/ Customized\nConnection: Flanged \/ Threaded \/ Welded\nBody Material: Carbon Steel \/ Stainless Steel \/ Customized\nApplication Medium: Liquid \/ Gas \/ Steam\nPressure Range: Customized\nNominal Size: Customized\nOperating Temperature: According to Application\n\nThe Self-Operated Pressure Regulating Valve provides a dependable, energy-efficient, and cost-effective solution for maintaining stable pressure in a wide range of industrial process systems.","brand":"LEO VALVES","offers":[{"title":"DN15","offer_id":43332293427294,"sku":null,"price":580.0,"currency_code":"USD","in_stock":true},{"title":"DN20","offer_id":43332293460062,"sku":null,"price":600.0,"currency_code":"USD","in_stock":true},{"title":"DN25","offer_id":43332293492830,"sku":null,"price":650.0,"currency_code":"USD","in_stock":true},{"title":"DN32","offer_id":43332293525598,"sku":null,"price":700.0,"currency_code":"USD","in_stock":true},{"title":"DN40","offer_id":43332293558366,"sku":null,"price":835.0,"currency_code":"USD","in_stock":true},{"title":"DN50","offer_id":43332293591134,"sku":null,"price":925.0,"currency_code":"USD","in_stock":true},{"title":"DN65","offer_id":43332293623902,"sku":null,"price":1050.0,"currency_code":"USD","in_stock":true},{"title":"DN80","offer_id":43332293656670,"sku":null,"price":1100.0,"currency_code":"USD","in_stock":true},{"title":"DN100","offer_id":43332293689438,"sku":null,"price":1580.0,"currency_code":"USD","in_stock":true},{"title":"DN125","offer_id":43332293722206,"sku":null,"price":1760.0,"currency_code":"USD","in_stock":true},{"title":"DN150","offer_id":43332293754974,"sku":null,"price":2090.0,"currency_code":"USD","in_stock":true},{"title":"DN200","offer_id":43332293787742,"sku":null,"price":2955.0,"currency_code":"USD","in_stock":true},{"title":"DN250","offer_id":43332293820510,"sku":null,"price":4500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0562\/7333\/8462\/files\/20260914105927.jpg?v=1789354887","url":"https:\/\/39e1b4-9a.myshopify.com\/products\/self-operated-pressure-regulating-valve","provider":"LEO VALVES","version":"1.0","type":"link"}
