ZZWT self- operated temperature control valve description

The quick-change self-operated temperature regulator is an energy-saving control valve requiring no external energy. It's used for temperature control of various heaters in non-corrosive gases and vapors. The pressure balance component is made of bellows and spring, which has high sensitivity, low noise and reliable performance. And it is free from maintenance and adopts standard modular design with high level of trigeneration. Multiple combinations control can be achieved through the assembly. The imported thermostat is adopted which makes it reliable with over temperature protection. It is maintenance-free and directly controlled by medium without external energy

Stainless steel bellows pressure balanced has low unbalance force and high sensitivity with over temperature protection.

It adopts standard modular design with high level of trigeneration. Multiple combinations control can be achieved through the assembly
