China Gold Supplier for TU-1J03 thermal wax actuator for thermostatic radiator valve to UK 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.

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!

https://w34.us/amz/B00AY9HJ10 A blowoff valve (BOV) or dump valve is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. Blowoff valves relieve the damaging effects of compressor “surge loading” by allowing the compressed air to vent to the atmosphere, making a distinct hissing sound, or recirculate into the intake upstream of the compressor inlet.
Hooked up correctly a BOV can hold pressure, and only open on vacuum. Hooked up as a relief valve it will open when pressure from the turbo gets too high.
In the case where a mass airflow sensor (MAF) is used and is located upstream from the blowoff valve, the engine control unit (ECU) will inject excess fuel because the atmospherically vented air is not subtracted from the intake charge measurements. The engine then briefly operates with a fuel-rich mixture after each valve actuation.
The rich mixing can lead to hesitation or even stalling of the engine when the throttle is closed, a situation that worsens with higher boost pressures. Occasional events of this type may be only a nuisance, but frequent events can eventually foul the spark plugs and destroy the catalytic converter, as the inefficiently combusted fuel produces soot (excess carbon) and unburned fuel in the exhaust flow can produce soot in the converter and drive the converter beyond its normal operating temperature range.
An alternative method for utilizing both a MAF and a blowoff valve is to have the MAF located down stream between the intercooler and the throttle plate. This is known as Blow-through rather than the traditional Draw-through set up. Care must be taken as to the position of the MAF to prevent damage to the sensitive element. For example, on a SR20DET motor, the MAF must be at least 12″ from the throttle plate, and the blowoff valve must be 6″ from the MAF sensor. By using a blow-through method, the MAF won’t be affected by the blowoff valve opening as the pressure is vented before the air reaches the MAF.
One approach used to mitigate the problem has been to reduce the boost pressure, which reduces the required venting volume and yields less charge over-calculation by the ECU. The air can also be recirculated back into the intake, a typical stock setup for cars with an upstream MAF sensor. The situation can also be corrected by switching the fuel metering system over to a manifold absolute pressure sensor, a conversion that usually requires a compatible aftermarket ECU or piggy-back fuel controller. The MAP sensor monitors the absolute pressure in the manifold at all times and will correctly detect the change that occurs when the valve vents, allowing the ECU to reduce fuel metering accordingly.
