valve  cover
Built-in pressure balance mechanism, 316 bellows +304 balance spring composition, through
Connecting nuts disassemble the adjusting mechanism and actuator.


actuator
Thermostat is the actuator of temperature regulating valve, which works according to the incompressible and thermal expansion and contraction pressure of liquid.
There are two models of temperature controller, a variety of temperature control range can be selected
special type
For clean working environment, no lubrication
