The new adjustable valve latest offer - Dan Fuss valve

 Dan Fuss adjustable valve works: DFX741X Dan Fuss adjustable pressure regulator valve mainly in two forms: diaphragm and piston type, mainly installed in the pipe high-rise building water supply systems and other water systems, will higher inlet pressure drop outlet pressure to meet the requirements. Having decompression reliable, easy to adjust, simply regulating pilot valve adjustment screw, you can get accurate, stable outlet pressure, can reduce the dynamic pressure, but also reduce static. DFYX741X Dan Fuss adjustable pressure regulator valve good energy saving effect, the use of semi-linear flow path width of the body, and so the flow area design, the small valve resistance, pressure loss, flow rate, system quick action and long service life . Important parts are made of special materials, to minimize the risk of repair. Dan Fuss adjustable pressure regulator valve - the main technical parameters DFYX741X Dan Fuss adjustable pressure regulator valve - installation and adjustment 1, the main valve shall be horizontal horizontal installation, before installation to completely remove the debris in the pipeline. Note that the main flow direction arrow outside the body, do not install the reverse direction. After installing the pipeline should ensure that no stress on the valve body and valve internal parts. 2, before the main valve to be put in a soft sealing valve (telescopic butterfly) and a filter, the main valve must also be installed after a soft seal valve (telescopic butterfly), in order to facilitate maintenance. 3, must be thoroughly flushed through the water before piping system. 4, test the water, slowly increasing the pressure, while paying attention to the main valve outside the control pipe leaks. 5, pilot valve and catheter control system has been completed to increase the pressure before leaving the factory assembly and adjustment, as pilot valve factory set pressure value is not suitable for on-site requirements, tighten or relax by the pilot valve to adjust the upper screw clockwise to tighten the screw , tighten the screw counterclockwise to reduce the pressure. After adjusting nuts. 6, the feed line should be installed bypass valve. 7, the main valve before the filter should be cleaned regularly. 8, this installation method, suitable for any diameter valves for easy maintenance in the future, allow enough space. 9. The main valve installed in the shadow of the well, the main valve four weeks should be enough space for maintenance, the main valve into the hole when the piston type to be higher than the upper end of the main valve for easy maintenance when lifting piston.
