Professional High Quality TU-1J90 thermal wax actuator for industrial thermostatic water regulations mixing valve – China Factories Detail:
1. Operation Principle
The Thermostatic 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 energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(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 nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.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 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. 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 thermal wax actuator is difference, it depends on its’ shell size.

The 3 X Factor – Three Exclusive Features
V-Seal
Rotex V-SealSelf Energized: Exclusive self energized double lip seal design for superior dynamic sealing. V-Seal operates over a broad range of instrument air pressures. Lower friction and less hysteresis for control applications.
Wear Compensating: V-Seals’ wear compensation feature eliminates the “set” taken by traditional O-rings. Greater temperature range and chemical resistance than O-rings. Actuator seal selection made simple!
Seamless Bearings
Rotex Seamless BearingTop Pinion Bearing: Rotex Infinity has a large solid top bearing to center and align the pinion for years of trouble free service and performance. Traditional “strip” bearings or O-rings offer less surface area and load capacity, reducing the overall life of the actuator.
Seamless Piston Head Bearings: Bearings are large one piece construction to support and guide the pistons under maximum load conditions. Bearings are molded directly to the piston, then machined concentric to the piston, centering the piston more precisely than strip bearings or O-rings possibly could.
Rack Engagement Bearings
Rotex Rack Engagement BearingsCenter Bore Sleeve: Provides the largest single piece bearings surface possible for complete piston rack support.
Internal Rack Guides: Durable guide blocks optimize rack teeth engagement for a lifetime of actuator cycles.
