YZ11X stainless steel pipeline pressure reducing valve belongs to direct-acting diaphragm pressure reducing valve, is in the original same type of pressure reducing on the improvement of a new type of pressure reducing valve products. Mainly by the diaphragm, valve flap, spring and other parts, the use of the diaphragm sensing downstream pressure changes to drive the valve flap lifting, thereby changing the pressure reducing valve opening to achieve the function of pressure stabilization, can make the water supply pressure distribution more uniform, to avoid part of the water supply overpressure, optimize the high-rise building water supply zoning. Mainly used in various building water system, fire fighting system, central air-conditioning system, heating system and so on.
Product Features
- Adopting direct-acting diaphragm type structure, the internal structure is very simple, no jamming, reliable performance and durable.
- Resistant to dirt and scale, no filter, no bypass pipe, extremely simple piping, can save a lot of space and piping costs.
- The outlet pressure is precisely adjustable, and in general, it can be considered that the outlet pressure is less affected by the inlet pressure.
- Excellent hydraulic characteristics with low pressure loss and pressure reduction ratios up to 10:1 or more.
- The enlarged and thickened valve body provides low-pressure and high-flow pressure reduction function, which can meet a variety of pressure reduction requirements, and is especially suitable for branch circuit pressure reducing valve system.
Installation Diagram
Pressure-reducing valves can be installed in any 360° direction, but the arrows cast into the valve body must correspond to the actual direction of water flow.
Caveat
- Rotate the adjusting screw clockwise, and stop rotating after the outlet pressure gradually rises to the required pressure. (The upper limit of the outlet after pressure reduction is 0.55Mpa, it is difficult to screw down the adjusting screw after the pressure is greater than this pressure, attention: excessive force will cause the diaphragm to break).
- Turn the one-word adjusting screw counterclockwise, and stop rotating after the outlet pressure is gradually reduced to the desired pressure. (Turn the one-word adjusting screw counterclockwise when pressure reduction is required. When there is no change in outlet pressure, it is necessary to relieve the pressure after the valve in order to make the pressure drop).
