Product model: ZZWP
Valve body material: WCB, 304, 316, 316L
Material of spool: WCB, 304, 316, 316L
Connection mode: flange, thread, welding
Pressure rating: PN16, PN25, PN40
Core Form: Fluid Pressure Balancing Core
Temperature Range: Overview of Self-operated Temperature Regulating Valve at 35 ~110
Self-operated temperature control valves do not need external energy-saving control valves for temperature control of various heaters in non-corrosive gases and vapors. Using bellows and springs as pressure balancing parts, it has high sensitivity, low noise and reliable performance. Suitable for non-corrosive liquids, gases and vapors. Temperature control in various heating or cooling systems. When the temperature of controlled medium rises, the control valve closes or opens.
Design features
1. It has pressure balance function, good sensitivity, high control precision and wide adjustable range.
2. Low noise, reliable performance and maintenance-free
3. Using standard modular design
4. Imported fixed-point regulator with reliable quality and over-temperature protection function
5. Multiple combinatorial control can be implemented by means of composite components.

Self-operated Temperature Regulating Valve Cover
Installed with pressure balancing mechanism, 316 bellows + 304 balancing spring, the adjusting mechanism and actuator are disassembled and assembled by connecting nuts.
Executing agency
Temperature controller is the actuator of temperature control valve. It works according to the incompressible pressure of liquid and the pressure of thermal expansion and contraction. There are two types of temperature controllers with different temperature control ranges.
Special type
For clean working environment, no lubrication is needed.
Mode of action: heating type and cooling type
Maximum temperature: cast iron: 180 C; cast steel: 350 C
