Features
SAV bolting and gasket system
- 316 stainless steel bonnet bolts will never come in contact with water or soil and are 100% protected against corrosion
- Unique gasket has round inserts for bolts, which are countersunk into the tapped valve body and capped with hot-melt
- Easily disassembled after years of service - but, you’ll never need to...
Stainless steel stem
- 400 series Stainless Steel is SAV’s standard stem material, providing twice the yield strength required by AWWA; Potential for bent and broken stem is eliminated
- Threads are cold-rolled, work-hardening the steel, and ensuring smooth thread edges for low operating torque
- Unique wiper-ring protects stem from contact with soil and water
EPDM wedge w/captive wedge nut
- Standard EPDM wedge is taste and odor free, stands up to chlorine and other disinfectants
- Wedge nut is fully encapsulated in the wedge, resulting in efficient mechanical motion and 10X the open/close operations vs. competitors; Provides higher torque resistance and prevents rubber wear and leakage
Serial number
- Every SAV valve has a unique serial number engraved on the stem – also shown on the valve label; Serial number provides complete traceability to the date the valve was built, and every operation performed throughout the manufacturing process
- SAV is the only gate valve and fire hydrant manufacturer in the USA with a Quality Assurance program that requires serializing every product for traceability
UL listing up to 24” diameter
- Model LD gate valves up to 24” are UL Listed at 200 PSI operating pressure
