Self-regulating valve is a need for any external drive energy, relying on the pressure of the media itself is transferred to the power source and media pressure changes, according to a predetermined value set, carry out energy-saving control device automatically adjusted. It combines detection, control, perform many other functions in a valve, self-contained independent instrument control system. The product is simple because no external energy, product structure, easy to use, less maintenance, etc., especially for urban heating, heating and no external power supply, gas supply and because they need to control the vapor pressure of the occasion. According to foreign reports, urban heating, heating system using this product, energy efficiency increased by 30% -40% higher than before, the effect is significant.
Feature
No external drivers of energy-efficient energy automation systems, low-cost equipment for explosive atmospheres; simple structure, less maintenance; adjustable set point and wide range of user-friendly continuously adjusted within the set range; diaphragm actuators Mechanical cylinder-type mechanism detect relatively high precision, quick action; with pressure balance valve mechanism, the regulator valve responsive, precise control, allowing the pressure large.
