China New Product TU-3A01 thermal wax actuator for electric switch valve for Roman Factory 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.

In this video we explore how to test and replace the EVAP pressure sensor P0450. If you’ve been following this channel you know we have a number of EVAP repair videos available. This video will add to that collection.
Trouble code p0450 deals with an improper voltage signal from the EVAP pressure sensor to the ECM. This could be due to a bad harness connector, the pressure sensor or the EVAP canister vent control valve. (link below for this component)
This sensor is used with a number of components in throughout the EVAP system. The EVAP control system pressure sensor is located in the purge line. The sensor detects pressure inside the purge line and modifies the voltage signal sent from the ECM. As the pressure increases the voltage rises. This sensor is used for on board diagnostics.
Tools Used:
Safety Glasses
Digital Multi-Meter
Vacuum Pump (Mityvac)
10mm socket & ratchet to remove sensor from chassis.
