The Self‑operated Temperature Regulating Valve is an automatic control valve that requires no external power source (electricity or compressed air). It opens and closes solely by the temperature change of the controlled medium. Its core component is a temperature sensor bulb (thermostatic bulb) and an actuating bellows.
Electric sleeve control valve
The Electric Sleeve Regulating Valve is a robust, high-precision solution for critical flow control in extreme industrial environments. Its sleeve-guided trim, smart electric actuation, and heavy-duty materials ensure reliable performance in oil & gas, power generation, and chemical systems. By combining advanced engineering with adaptive control, this valve delivers unmatched stability and efficiency under the most demanding conditions.
