Operation: Self-operated actuator Self-operated temperature regulator (heating type and cooling type) is composed of the control valve and a temperature controller. It is suitable for controlling temperature of non-corrosive liquids, gases and vapors in various heating systems. When the temperature of the controlled medium rises, the control valve is closed.  Parameters of Self-operated temperature regulator： Trim features： 1. Built-in bellows provided with pressure balanced structure and high sensitivity 2. reliable performance, free of maintenance 3. The standard modular design is adopted 4. Provided with pointer and dial, adjustable temperature Body type: straight-through type Bonnet type: standard type, heat dissipation type Flow characteristic: quick open Size: DN15-150(1/2''-6'') Pressure class: PN1.6, 4.0Mpa(ANSI 150, 300LB) Leakage class: ASME B16.104 Ⅴ(soft seal), ASME B16.104 Ⅳ(metal to metal seated) Pipe connection type: flange type Set value error: ±3.5℃ Applicable temperature range: -20℃ ～ 250℃ Actuator type: temperature controller www.valve-cn.com
