Since the seat is made of a carbonized Teflon seal ring and a disc spring, it is highly adaptable to changes in pressure and temperature, and does not cause any slippage in the marked pressure and temperature range.
structure
City gas: gas output pipelines, main lines and supply lines for each branch line.
Central heating: large heating equipment output pipeline, main line, branch line.
Heat exchanger: The pipeline and each circuit are opened and closed.
Steel plants: various fluid pipelines, exhaust gas pipelines, gas and heat supply pipelines, fuel supply pipelines.
Various industrial equipment: various heat treatment pipes, various industrial gas and heat pipes.
characteristic:
All welded ball valves will not have external leakage.
The processing of the sphere is tracked and detected by an advanced computer detector, so the processing accuracy of the sphere is high.
Since the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be deformed due to earthquakes and vehicles passing through the ground. The pipe is resistant to aging.
The seal ring body is made of RPTFE with 25% Carbon (carbon) to ensure complete leak-free (0%).
The direct-buried welded ball valve can be directly buried in the ground. It is not necessary to build a large valve well. It is only necessary to set up a small shallow well on the ground, which greatly saves construction costs and engineering time.
The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
The processing precision of the sphere is very precise, the operation is light, and there is no adverse interference.
Using advanced raw materials, it can maintain pressure above PN25.
Compared with the same specification products of the same industry, the valve body is small and the appearance is beautiful.
The service life is more than 15 years under the condition of ensuring normal operation and use of the valve.

A 24V Dc Motor Consistency is good, reliable performance, low malfunction, torque, motor no-load and load running more smoothly and the lowest in 50 decibels
Functions: 24V dc motor rotor part of the armature iron core, armature, commutator and other devices, 24V dc motor is suitable for most of the electronic products, such as Electric curtains, car, sweeping robot, no hakaze fan, etc
Areas of application:
Method of use: the best stable in horizontal plane, installed on the 24V dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the 24V dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
24V dc motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a 24V dc motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
24V dc motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
