China Manufacturer for TU-1C90 thermal wax actuator for thermostatic automatic water drain valve for Iran 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 the Saab 9-5 there is a valve (Coolant Bypass Valve or Heater Bypass Valve) in the cooling system that is prone to failure, resulting in leaking coolant. The leakage can be sudden and the car can loose a lot of coolant in a very short time. If unlucky, this can happen on the highway and result in an overheating engine.

    A few months ago the coolant bypass valve in our Saab 9-5 Aero from 2002 developed a large leak just as we were going on a long-awaited roadtrip. Since it was Friday evening, no mechanic would be able to look at it before Monday. Luckily we were able to buy a new valve (roughly 400 SEK or €40) from the local auto parts store and install it within two hours. In this video I show you how to some of the things I learned and some of the best tricks for this repair.

    If you are watching this video because your car suddenly started leaking, don’t worry. While the repair might be a little cramped, it’s not difficult if you have the right tools. Note that this is not a full repair video since we already replaced the valve.

    Tools needed:

    Replacement bypass valve, Saab Part No 90566947.

    Wire-operated hose clamp pliar. Highly, highly recommended. This one tool will make your day, and is well worth the money even if you only need it for this one job.

    Bungee cord. Cheap to buy and highly recommended to pull the wiring harness to the right side of the engine, giving you more access to the valve.

    Remember to turn off the AC when you are warming up the engine after re-filling the coolant. This allows the coolant to enter the heat exchanger and remove any air bubbles inside there.

    Be sure to run the engine at least until it has reached operating temperature and then check the coolant level again.

    I also recommend changing your vacuum lines while you have access to your coolant bypass valve. See my video on this topic here: https://www.youtube.com/watch?v=g6kWoCzDBdg

    Did this video help you? I would love to hear from you in the comments!

    Swedish: Denna video visar hur man byter värmekran (även kallad värmeventil eller by-passventil) på en Saab 9-5. Plötsliga läckage av kylarvätska har ofta att göra med att denna kran läcker. Det är starkt rekommenderat att du köper en vajerstyrd slanglämmetång och en gummilina, dessa verktyg gör det mycket enklare.

    One of the best uses for Flexinol® actuator wire is in electronic locks. The Flexinol® actuator wire provides a small but strong alternative to motors or solenoids. The Dynalloy Latchbox™ is an example of a simple and low cost latch. The box latches closed and when activated electrically, the small diameter Flexinol® actuator wire contracts opening the latch and opening the lid. This is only one demonstration of one of the many possibilities Flexinol® actuator wire has in latches.
