Self-pressure regulating valve double circuit

Product description Self-pressure (DP) control valve, the valve, valve seat, valve parts and other component parts, is a no external energy is transferred directly to rely on the media itself is pressure changes automatically adjust the pressure of energy saving Products can be used for non-corrosive (maximum temperature 350 degrees C) pressure means liquid, gas and steam and other media. Widely used in petroleum, chemical, metallurgy, light industry and other industrial sectors and urban heating, heating system. Features Self-pressure regulating valve without external energy, energy without electricity airless place of work, convenient and saves energy. Fine pressure segment range and cross-cutting, high regulation accuracy. Pressure setpoint can be set continuously during operation. After pressure regulator valve, the valve before the pressure ratio of the pressure and the valve may be 10: 1 to 10: 8. Rubber diaphragm-type detector, high measurement precision actuators, quick action. Using pressure balance mechanism, the regulator valve responsive and precise control.
