YAWR -1/1K (KC marked) Type Pressure Reducing Valve 10K

As a large capacity pressure reducing valve, this product is used for construction facilities, plants, and water-supplying lines for agricultural use. Because the pilot valve has a pressure balance structure, it maintains a constant secondary pressure level, regardless of changes in the primary pressure.
 

Features

• Special seat structure : it prevents a water hammer when the valve is opened and closed.
• Reliant and easy to use by Needle valve adjustment according to field conditions
• Simple to adjust and maintain due to easy disassembling of valve body and pilot valve

▶ The primary and secondary pressure gauge is attached upon client’s order.
▶ The direct operating type (YPR-2A) should be selected for control of small flow.
▶ A pipeline needs to be installed in parallel with the direct operating YPR-2A if there is a need for flow control within 10% of the rated flow.
▶ Strainer (over 40 Mesh ) installation is required to ahead inlet when valve installing.
▶ KC marked products are order made
