Detailed Product Description: | Product Description Shanghai Valve Factory (http://www.shzxv.com/) is Xuan valve production YZ11X manifold pressure reducing valve (http://www.shzxv.com/jyf/yz11x.html) is mainly used for a variety of building water supply systems, heating systems, fire systems, central air conditioning system. YZ11X manifold pressure reducing valve is used to support tube decompression, allows water pressure distribution is more balanced, to avoid part of the water supply overpressure and optimize the high-rise building water district. YZ11X manifold pressure reducing valve can replace the partition FM variable speed pumps, fire water supply system to replace the partition pumps for household water supply system to protect all the taps and other water appliances. Support YZ11X tubular valve works: the role of the branch pipe pressure relief valve outlet pressure at the diaphragm bottom and the underside of the flap valve, when it exceeds the spring settings, compression spring, so that the valve closed. Downstream anhydrous flow, the outlet pressure will be kept at the set value (the change was only 8% of inlet pressure variation); outlet pressure drop when the downstream water, the springs push the diaphragm to open the pressure relief valve. Continuous flow circulation after a while the valve is open since the damping effect of the opening and closing action has stabilized. Four manifold pressure reducing valve as possible causes frost damage in cold areas should be noted that insulation. Wrong direction of flow, pressure reducing valve into a check valve, the outlet pressure of 0. Spring screw too tightly, can not be closed, the valve will be through the P2 = P1. The bypass pipe was leaking, so that P2 deviate from the set value, in view of the YZ11X manifold pressure reducing valve superior reliability and durability, it is recommended not to install the brightness through the pipe is appropriate. YZ11X manifold pressure reducing valve Features: (1) YZ11X support tube valve with a direct role in diaphragm structure, the internal structure is very simple, no jamming, reliable, durable. Waterproof dirt dirt, no filter, no bypass pipe, piping is extremely simple, can save a lot of space and piping costs. Precision adjustable ② outlet pressure, in normal situations, that the outlet pressure from inlet pressure (outlet pressure variation is 8%) of △ P1. ③ excellent hydraulic characteristics, pressure loss, decompression can be reached 10:1 above. YZ11X manifold pressure reducing valve to meet a variety of decompression requirements, in particular, applies manifold vacuum system.
