Series 03: Small Diameter Gate Valves
The series 03 valve is our small diameter valve (1-inch to 3-inch) with NPT threaded ends. These valves meet the applicable requirements of AWWA C509. The Series 45 valves also include a 2-inch valve with Push-On ends.
Features:
- All AVK gate series 03 valves meet or exceed the applicable requirements of AWWA C509
- Stainless steel stem - standard
- Lead free
- Threads rolled in a separate cold pressing process to enhance strength
- Rolled threads ensure smooth thread edges and low operating torques
- Twice the yield strength required by AWWA eliminates bent and broken stems
- Stainless steel bolts - standard
- Packing gland bolts and bonnet bolts are stainless steel for corrosion resistance
- Bonnet bolts are countersunk and capped with hot melt to totally isolate the bolts from corrosive environments
- O-ring bonnet gasket wraps each bolt to prevent corrosion
- Bonnet blow offs due to bolt corrosion eliminated
- Fully encapsulated wedge with EPDM - standard
- Ductile iron or bronze wedge fully encapsulated in EPDM rubber with an integral bronze stem nut for optimum corrosion protection and precision wedge tracking
- EPDM resists attack from chloramines
- Wiper ring - to prevent impurities from entering the stem and to protect the o-rings
- Two o-ring stem seals to reduce friction and prevent wear and tear - replaceable under full pressure
- Third o-ring stem seal protects upper stem from impurities entering from the water way
- Coating to AWWA C550 - Electrostatically applied fusion bonded epoxy coating inside and outside for excellent corrosion resistance
- 100% testing - All valves tested to 250 PSI / 500 PSI as required by AWWA
