American Flow Control's 14"–66" Series 2500 Ductile Iron Resilient Wedge Gate Valves are suitable for use in potable water, sewage, and fire protection systems. These valves have a rated working pressure of 250 p.s.i.g. The valves seal 100% leak tight.
ADVANTAGES OVER BUTTERFLY VALVES
- No disc in waterway to restrict flow or to increase pumping costs.
- Allows passage of pigging devices.
- Internal parts can be serviced without cutting valve out of pipeline.
- 250 p.s.i.g. rating provides for future pressure increases over the 150 p.s.i.g. pressure rating found on most butterfly valves.
ADVANTAGES OVER DOUBLE DISC GATE VALVES
- 100% bottle-tight seal. No more time-consuming testing to determine allowable leakage rate.
- No pocket in bottom of valve to collect sediment or trap debris.
- Lower torque requirements to operate valve.
- 250 p.s.i.g. pressure rating compared to the 150 p.s.i.g. rating found on double disc gate valves.
- Epoxy-coated inside and out.
- Lighter total valve weight.
The 14"–66" Series 2500 Resilient Wedge Gate Valves have these standard features:
- 250 p.s.i.g. rating
- Thrust washers
- Rubber-encapsulated wedge
- Fusion-bonded-epoxy coating
- Flats on valve body so valve stands upright for storage or during installation
- Ductile iron body, bonnet, and wedge
- Triple O-Ring stem seals
- 100% bottle-tight closure
- Optional gearing (standard on 30" and larger)
- Low operating torques eliminate need for by-pass valve
- NSF approved coating
- All assembly nuts and bolts are stainless steel
