Product overview:
Steel fully welded pressure differential control valve is a new product developed by Hebei Tongli Automatic Valve Manufacturing Co., Ltd. It is mainly used in urban central heating and central air conditioning in the water circulation system. The advantage of this valve is that the pipe network is installed using welding, which fills the gap in the original self-operated differential pressure control valve that does not have welded connections.
Product technical parameters:
Caliber:
Pressure level: .
Working temperature: ℃
Used medium: water
Connection method: welding
Pressure difference adjustment range:..
Pressure difference control range:..
Technical features:
. Change the original casting process of the pressure difference control valve, and the valve body is made of steel pipes and welded. .
.The connection method adopts welding, which eliminates the need for flanges, bolts and gaskets connected to the pipeline, saving a lot of material resources. Make the pipe network safer, more stable and have a longer service life.
.The inner wall of the valve body is smoother and the resistance is small, making the pipe network operation more convenient and stable.
. Directly welded into the pipeline makes the project with higher pressure resistance and makes the pipeline network operation more stable and safer.
.It should be used for thermal insulation in HVAC projects to reduce a large amount of heat loss.
Operation method:
Connect the valve seat to the pipe, install it into the valve body, hydraulically close the valve body, and then weld the connecting pipe to the valve body. Weld the connecting sleeve on the valve body. Then screw the diaphragm box equipped with the valve core, diaphragm and spring on the connecting sleeve, install a pressure regulator on the outside of the diaphragm box, and connect the pressure guiding tube.
