Self-reliance type regulator have energy saving function, because of this, in a little stem not demanding occasions are widely used. Self-reliance type regulator to have accused media must be required, for example, self-reliance type pressure regulator was accused of medium temperature should be lower than a specified value, the media should be neat, when the medium temperature is higher, for example, used in liquid, steam or above 150 ℃ should be set condenser, make into the actuator comparator in the medium temperature is lower than the specified value. 。 Self-reliance type pressure regulating valve based on pressure point location points before and after valve valve, pressure points in front of a valve is used to curb before the valve pressure fixed eternal; After the pressure points in the valve, for stem valve after pressure fixed eternal. Self-reliance type valve is a kind of survey, stem, and become one executive function, USES the object itself can + 羭 help and its action of stem valves, directly to the utility type and with the command utility divides into two classes. The gas medium, can be directly will be accused of gas into the membrane. The structure of the actuator is roughly similar pneumatic diaphragm actuators. With steam medium, can see fit and use the medium of the condenser will be steam condensation, try our best to take care of head into the membrane medium temperature in the presence of background, prevent the diaphragm damaged. Its unique place is simple in structure, convenient in operation, but will be actuating pressure drop, cause the outlet pressure of the nonlinear, generally, voltage regulation precision in 10 ~ 20 one hundred percent and one hundred percent. Take command of self-reliance type regulator can be suitable for use in Marine valve small pressure drop and high flow rate of self-reliance type stem situation, outlet pressure fluctuation range can be less than 10 one hundred percent of set pressure. Self-reliance type regulator membrane actuator input signal is stem head at the ends of the valve or valve after pressure or differential pressure, temperature or the bag after a change in the pressure signal. Direct utility self-reliance type process itself of pressure or differential pressure regulator used to drive the regulator movement, also can use the bulb type testing components for the temperature change of pressure, and then drive the regulator. Q: what is self regulating valve a: self-reliance type regulator is called direct utility regulator, is a broad categories without additional energy material drive regulator. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
