First, self operated pressure regulating valveProduct overview
Self operated pressure regulating valveThere are single seats in the seriesZZYP(sleeve)ZZYM(), doubleZZYNThere are three kinds of structure; the actuator has two types of film and piston; the action mode is pressure regulation after decompression valve(Btype)Pressure regulation of valve before pressure reliefKType. The nominal pressure grade of the product is availablePN164064Diameter range of valve bodyDN20300There is a leak levelIIClass,IVAndVIGrade three; quick opening flow characteristics; pressure regulation from152500Kpa. Can be assembled according to the requirements to meet the user's working conditions.
Our company producesZZYtypeSelf operated pressure regulating valveWithout additional energy, the energy of the medium itself is used as the power source to introduce the actuator to control the spool position, change the pressure difference and flow at the two ends, and stabilize the pressure before or after the valve.Self operated pressure regulating valveIt has the advantages of sensitive action, good sealing, small pressure setting point wave power and so on,Self operated pressure regulating valveWidely used in gas, liquid and medium pressure regulation or automatic control of pressure relief and voltage stabilization.
Two. Self operated pressure regulating valveProduct features
(1The self operated pressure regulating valve does not need additional energy, and can work in the place without electricity and gas, which is convenient and saves energy.
(2The pressure section ranges are fine and cross each other, and the adjustment precision is high.
(3The pressure setting value can be set continuously during operation.
(4) to adjust the valve after the pressure valve, pressure valve before the pressure ratio and after101108
(5Rubber diaphragm test, the actuator measurement accuracy, sensitive action.
(6The pressure balance mechanism is adopted to make the regulating valve sensitive and accurate.
