What is the difference between Tieling electric proportional butterfly valve and electric two position butterfly valve? Method 1: increase sealing grease If the butterfly valve has not used sealing grease, consider increasing sealing grease to improve its sealing performance.
、 The special valve for liquefied gas must be able to "identify" steam and condensed water, so that it can act as a butterfly valve to block steam and drain water. The "identification" of steam and condensed water is based on three principles: density difference, temperature difference and phase change. Therefore, three types of special valves for liquefied gas are manufactured according to the three principles, which are classified as mechanical type, thermal static type and thermal dynamic type.
