Pilot Drive Self-operated Regulators are typically used for these applications which need large flowrate or precise pressure control is required. Pilot-operated Pressure Relief Regulators are consisted of a main valve and a pilot valve, when the pilot valve detected the upstream pressure rises, it will respond quickly and accurately to open the pilot valve, after the pilot valve opens, the main valve will also open by the upstream pressure. Through the above two paths, the regulator achieves the purpose of pressure relief.
Features:
1. The Pilot Drive Self-operated Regulators do not require external energy, and can work in places without electricity and air power, which is convenient and energy-saving;
2. A large and sensitive detection diaphragm ensures the pressure accuracy of the control point;
3. The signal detection actuator is separated from the power actuator so that the pressure reduction ratio of the whole pressure regulating valve can reach 2000:1;
4. An adjustable flow device is added, which is easy and convenient to debug;
5. The valve trim is designed with a pressure compensation device, which completely eliminates the influence of pressure fluctuations on the accuracy of the set point, and the adjustment is more stable;
Benefits:
1. The whole regulator adopts no filler design, and the action is fast;
2. The range of pressure set point is thin and interlaced, which is convenient for selection;
