Dual Seat Regulating Valve

Double seat regulating valve refers to a regulating valve with two valve cores and two valve seats forming two valve seals between the inlet and outlet of the valve. It can be divided into electric control and pneumatic control, and can input control signals of DC4-20mA or DC1-5V for control. According to the signal of the regulating part, the opening of the valve is automatically controlled to achieve the regulation of medium flow rate, pressure, and liquid level. The double seat regulating valve produced by Shanghai Meiyan Yi Pump Valve is particularly suitable for situations with large pressure differences, allowable leaks, and media that are not very clean. The flow characteristics mainly include linear characteristics, equal percentage characteristics, and parabolic characteristics, which determine the control effect and accuracy of the regulating valve under different working conditions. Its product has a nominal pressure rating of DN25-400 and is suitable for a wide range of fluid temperatures, from -250 ℃ to+560 ℃.
