ARD Metal Seated Gate Valves AWWA C500 Rotating Disc Gate Valves

American R/D Series 50 Rotating Disc gate valves are a time proven product. This design has been manufactured and in service

since 1908. These valves meet all requirements of AWWA C500, latest revision, and applicable ANSI, ASTM, and other industry

standards. American R/D has more metal seated gate valve manufacturing and engineering experience than anyone in the industry.

3” - 54” valves are rated at 250 psi and hydrostatically tested to 500 psi –ductile iron construction. Sizes 60” - 108” rated at 100 psi

and tested at 200 psi

Rugged, full body thickness- more iron better resistance to corrosion

Selection of coatings — internally and externally — NSF-61 approved — meets AWWA C550, protects interior and exterior

All working parts are perfectly plain with no pockets to collect sediment or prevent free and easy movement

Internal parts cannot be assembled incorrectly or become disengaged while in service

Revolving discs, which seat in different positions each time the valve is operated, ensure maximum life in the most exacting

conditions

Extra-wide disc and body seat ring faces provide a large seating area

Bypass valve equalizes pressure to ensure less stress on the discs when opening/closing the valve

Series 52 = Non Rising Stem FLANGED

Series 55 = Non Rising Stem MECHANICAL JOINT

o Series 525 = Non Rising Stem MECHANICAL JOINT by FLANGED

Series 59 = Outside Screw & Yoke FLANGED

o Solid Wedge Gate Valves

American R/D 100 Line Solid Wedge valves meet all requirements of AWWA C500, latest revision, and applicable ANSI, ASTM,

and other industry standards.

Valves available in NRS or OS&Y style

Adjustable packing gland with non-asbestos packing

Heavy duty full body wall thickness made in ductile iron

Available with flanged ends, MJ ends, grooved ends, or any combination

Full flow waterway

Selection of coatings — internally and externally — NSF-61 approved — meets AWWA C550, protects interior and exterior

Full guides engage with body guide to maintain parts in position: Valves 16" and larger use bronze wedge and body guides

Extra wide wedge and body seat ring faces provide a large seating area

Solid one piece tapered wedge assures excellent performance and prevents clogging

Corrosion resistant one piece stem made of high strength stainless steel

Close fitting stem to wedge engagement maintains component alignment

Bypass valve equalizes pressure to ensure less stress on the discs when opening/closing the valve
