Factory Promotional TU-1F06 thermal wax actuator for thermostatic automatic water drain valve to Malta Manufacturer 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.

Most electric vehicles still adopt the braking system of fuel vehicles and gain additional braking power with EVP or Bosch iBooster. As for these electric vehicles, ESC is still the master controller of braking system. But things have changed. As electric vehicles can, through AC motor, achieve reverse deceleration and recover braking energy, the load of EV braking system reduces considerably. And the new technology drive-by-wire braking system can thus be used.
Drive-by-wire braking system has been extensively used in F1cars, and is replaced when the driving range reaches less than 2,000 km, which causes high costs. Its braking sensitivity is much higher than that of traditional braking systems. Moreover, its flexibility increases dramatically. Hence, the braking system is very practical in the field of ADAS and self-driving. This is why Tesla can achieve intelligentization more easily. Drive-by-wire braking system substitutes ESC system or TCS (traction control system), which allows vehicle manufacturers to get rid of dependence on ESC manufacturers. Tesla Model S, Porsche 918 Spyder, and Audi R8-ETRON adopt this design. There are two systems inside the car: one is traditional front wheel hydraulic brake without EVP, which has the function of ABS; the other is rear-wheel drive-by-wire braking system, which uses electrical signal and motor to control brake calipers.
The disadvantages of drive-by-wire braking system are also evident: first, small braking force due to limited motor power; second, high requirements for heat resistance of brake discs. Porsche 918 Spyder and Audi R8-ETRON adopt ceramic brake discs while Tesla uses high-grade ITT brake discs. Third, due to small volume left for braking motor, only permanent magnet motor can be used. And when you put on brakes, permanent magnet has long been working under the high temperature, thus leading to demagnetization. The reliability of drive-by-wire braking system is yet to be tested. At present, the system, which incurs high costs, can not be used as main braking system but only as auxiliary brake.
In the field of EPS, things get better. China acquired Nexteer, and some enterprises can produce low-end C-EPS. However, the future development of EPS is targeted at R-EPS. There is still an obvious gap between at home and abroad. EPS market is highly concentrated, with the top four manufacturers holding a combined market share of over 75%. The market share of Jtekt exceeded one third. After selling ZF Lenksysteme, ZF still has TRW steering business, reflecting that it has placed emphasis on steering system.
SM series motorized brass ball valves with compact electric actuators are offered in on/off or modulating via control signal. Modulating valves are available with a flow optimizing disc which provides the precise flow control needed for HVAC applications.
Assured Automation’s SM Series motorized ball valves are two way quarter turn ball valves with a compact “Sure Mount” electric actuator.
There are two distinct types of ninety degree rotary actuators available. One is a basic on/off unit with valves either fully open or fully closed. The other is modulating and can be accurately positioned anywhere between 0 and 90° using a control signal. The on/off units are fast acting with an actuation time of five seconds. They are available with nickel plated or lead free brass ball valves.
Assured Automation offers a variety of lead free brass products including manual and automated ball valves, check valves and flow meters.
The modulating units operate much more slowly and come with or without flow optimizing discs. This makes them perfect flow control valves for HVAC applications. The purpose of the flow optimizer is to make the flow rate increase evenly in direct proportion to the rotation of the ball. These curves clearly illustrate the principal.
See how the percentage of flow on the valve with the optimizer disc increases at a steady slope as the ball rotates. Whereas on the valve without the optimizer here is a sudden increase in the middle and not much change near the fully open and closed extremes. This provides precise control for applications like mixing water on heat exchangers.
The most prominent feature that both of these actuator types share is the quick and easy “sure mount” mounting system that connects them to the “sure mount” valve stem.
But don’t be fooled by this tiny locking pin, the use of minimal hardware in theis simple design still provides a reliable connection from the actuator to the valve.
To remove the actuator, simply pull out the locking pin and pull off the actuator, its that easy!
Once the actuator has been removed, the Sure Mount valve can be manually operated using a standard screwdriver. The slot in the valve stem is always parallel with the ball drilling providing a reliable indication of the ball’s position at anytime.
To replace the actuator, first make sure the actuator drive tab and the valve stem slot are in the same orientation. If they are not, rotate the valve stem with a screwdriver to align, then press the actuator onto the valve stem. Next, simply replace the locking pin on either side.
There’s a reason this valve is rapidly becoming a favorite in the HVAC industry, it’s a great valve at a great price!
