With many countries in long-term droughts and experiencing depleted aquifers, wastewater reuse is becoming more and more a viable option for water supply.This leaves growth potential for manufacturers of valve products suited for the purpose.
Daryu resilient-seated valves are well suited, ideal for utilization in applications up to 250 psi for valves up to 12 inches and 150 psi for 14 inch and larger, with temperatures up to 250 degrees F and pipeline velocities at or below 30 feet per second.
Daryu is superior to others in part because of its fully diverse line of products used in every facet of water filtration and wastewater treatment.The wall thickness is two time as thick as normal type, better bearing performance.Solid body, drilled by machine, ensure the concentricity, reduce friction effectively. We can supply ANSI B16.1Class125, DIN2501 PN10/16, BS4504 PN10/16, JIS10K body type for customers reference.
Use high quality EPDM seat, -20-135℃, enhance tightness between body and seat. With the advantages as follows:widely used in industry pipeline, easy replacement, longer service life. Test result shows seat has no influence after open and shut over 10000 times. Also supply NBR, PTFE, CSM, Viton, CR seats etc.
High precision disc external edge, reach requirement of bubble-tight, low torque, long service life. The max working pressure is PN3.0 We supply Ni plated DI, SS304, SS316, bronze, WCB,DI coated nylon for your choose.
Galvanized carbon steel shaft, smooth and anti-rust, reduce friction effectively.single, double shafts with square, ellipsoid and circular edge for your choose. We can supply SSS416, SS304, SS316 materials according to different working medium.Stainless steel bolts and nuts, rust-resistant, long service life.Use spring washer and flat gasket, effectively prevent loose when pipe shock.
Daryu Resilient Seated Butterfly Valves are designed, manufactured and tested to meet or exceed AWWA C504, Section 5.0 performance criteria.For all your water needs, Daryu has the solution.
