Features

◔ Material

Ductile Iron ASTM A536, 65-45-12
Body, bonnet, wedge, handwheel and operating nut are all produced in ductile iron material which provides guarantee for high strength and good corrosion resistance.

◔ Triple O-ring Stem Seals

The lower O-ring isolates the stem thrust collar bearing area from the waterway. The upper two O-rings can easily be replaced in the line while the valve is under pressure in the open position.

◔ Stainless Steel Stem, Brass Thrust Collar and Bronze Wedge Nut

This life-tested MEIDE design has repeatedly proven its superior strength and abrasive resistance.

◔ Fusion Bonded Epoxy Coating

Fusion bonded epoxy coating in accordance with ANSI/AWWA C550 for both interior and exterior surface which provides reliable corrosion resistance.

◔ Long Service Life with Resilient Seat Cycling Test 1,000 times

The Valve has been subjected to 1,000 cycles of operation at a maximum rate of 6 cycles of operation per minute from fully closed to fully open and from fully open to fully closed positions under cycled hydrostatic pressure.
