Professional Design TU-1F06 thermal wax actuator for thermostatic automatic water drain valve for Stuttgart Factories
Professional Design TU-1F06 thermal wax actuator for thermostatic automatic water drain valve for Stuttgart 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.
(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.

Inside the actuator
Our Price Pfister 809-7C Avante Tub / Shower single control was leaking behind the control knob. I was unable to find any information on the internet for replacement parts so I call Price Pfisters consumer service help line. (1-800-732-8238). I told them my problem and they sent me a new 974-2920 control cartridge free of charge. Got it five days later. Great service!
A very good suggestion below from tripjet999. After you remove the old valve. Stop and use a light to check for any debris/foreign material inside the chamber, prior to replacing valve.
