YPR-ST(Flanged) - Type Pressure Reducing Valve for water Flanged end JIS 10K

This is a direct operating pressure reducing valve for cold and hot water that can be used for small to large flows, with a small pressure fluctuation range. Used for construction facilities, this valve is employed for pressure control of each level’s water supplied by an elevated water tank of a medium or high-rise building; as well as for pressure control of feed water from a directly-coupled pump and other boiler feed water.
 

Features

• Outstanding functions for controlling the pressure of water supplied by a building’s elevated water tank to each floor.
• Easy to handle : small size and light weight.
• Two ways to install : horizontally or vertically.
• A constant pressure level with only a single adjustment.
• Wide flow range ability : an outstanding level of minimum adjustable flow & adjustable and stable in a wide flow range.
• All parts can be disassembled through the top of the valve : complete repairs even in limited spaces is possible.
• Built-in spring-type orifice that prevents a water hammering action.
• Linear flow pass-through method, which removes noise during operation.
