YPR-8Z(20K) Type Pressure Reducing Valve to each Household For heating and supplying water 20K

Pressure reducing valves that are used to supply water to each household are
designed to resolve problems that arise from a pressure imbalance in water supplied
to households. They promote user convenience by allowing easy changes of the
pipeline direction in accordance with field conditions.
Features

• It prevents waste of water resources by controlling irregular pressures among households in apartment buildings.
• As a union type, the pipeline can be changed easily according to field conditions.
• No additional errors resulting from the idle rotation of the flowmeter; by preventing pressure imbalance of water flow among households and blocking countercurrents to “low pressure” households.
• Its optimal design considers the maximum concurrent usage rate by supplying sufficient flow, based on an appropriate pressure level, even at peak load.
• Built-in strainer blocks entry of foreign substances and reduces installation space.
• Identifies precise adjusted pressure level and reduces installation space.
• Improvements in cross-sections polishing on the flow path to minimize resistance loss and reduce noise.
