Electric Actuator Valve Core, 1700

Model Number: Electric Actuator Valve Core 1700 Brand Name: TU-POLY Key Specifications/Special Features: Operation principleThermostatic wax that has been sealed in shell body induces expansion by a given temperature and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energyThermostatic wax brings an upward movement to its handspike and automatic control of various function are realized by use of upward movement of handspikeReturn of handspike is accomplished by negative load in a given returned temperatureCharacteristics:(1) Small body size, occupied limited space and its size and structure may be designed in according to the location where needs to work(2) Temperature control is reliable and nice
(3) No shaking and tranquilization in working condition
(4) The element doesn’t need special maintenance
(5) Working life is long

Main technical parameters:
(1) Handspike’s height may be confirmed by drawing and technical parameters
(2) Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5 to 20 mm
(3) Temperature control range of thermostatic element is between: -20 to 230°C
(4) Lag phenomenon is generally 1 to 2°C
Friction of each component part and lag of the component part temperature cause a lag phenomenon
Because there is a difference between up and down curve of traveling distance
(5) Loading force of thermostatic element is difference, it depends on its’ shell size
