| Product Introduction |
|
Self operated electric temperature control valve (suitable for larger diameters and thermal oil control), the biggest feature of this valve is that it only requires ordinary operation220VPower supply, utilizing the energy of the regulated medium itself, directly adjusts and controls the temperature of media such as steam, hot gas, hot oil, and gas, and can also be used to prevent overheating or heat exchange,The valve has a simple structure,easy operation,Choose a wide temperature range, fast response time, and reliable sealing performance,And it can be adjusted freely during operation,Therefore, it is widely used for hot water supply in sectors such as chemical, petroleum, food, textile, hotels and restaurants

|
|
The nominal diameter of this series of products ranges from 20 to 200mm, with nominal pressures of 1.0, 1.6, 4.0, and 6.4MPa. The operating temperature range is from -20 ℃ to 350 ℃, and the received signal is from 0 to 10mA DC or 4-20mA DC is used to change the flow rate of the regulated medium to maintain the controlled process parameters at the given values. The single seat regulating type is suitable for situations where the pressure difference is small, the medium viscosity is high, or there are slight particle impurities. Sleeve adjustable type is suitable for situations with large pressure difference
