Electric single seat regulating valveIt is a pressure balanced regulating valve. Accept the DC current signal from the regulating instrument, change the flow rate of the regulated medium, and maintain the controlled process parameters at the given values. Widely used in the production automation control of industrial sectors such as power, metallurgy, chemical, petroleum, textile, pharmaceutical, papermaking, etc.Control various high-pressure fluids with high and low temperatures,Good dynamic stability, low noise, and cavitation corrosionErosion smallIt is a pressure balanced regulating valve.
Electric single seat regulating valveIt is a new self operated regulating valveTypes. Compared to manual operationcontrol valveIts advantage is the ability to automatically adjust; Compared to electric control valvesIts advantage is that it does not require external power. Practical application has proven that in closed water circulation systems such as hot water heating systems and air conditioning chilled water systems, the correct use of this valve can easily achieve flow distribution in the system; Can achieve dynamic balance of the system; It can greatly simplify the debugging work of the system; Can stabilize the working state of the pump, etc.
Characteristics of regulating valve: 1. Large adjustable range, inherent adjustable ratio of 50, flow characteristics with straight lines and equal percentages.
2 The valve body is designed according to the principles of fluid mechanics, with a low flow resistance flow channel of equal cross-section, and the rated flow coefficient is increased by 30%.
3 The regulating cut-off type adopts a soft sealing structure valve core, which meets the VI level leakage standard (zero leakage).
4 Adopting deep dynamic negative feedback can improve the accuracy of automatic adjustment.
5 The bellows sealed regulating valve forms a * seal on the moving valve stem, blocking fluid leakage.
6 The valve opening can be directly controlled by the current signal without the need for a servo amplifier.
