Description

Design Features:

1、 Ductile Iron body and bonnet for high strength and impact resistance . Valve Body and Bonnet Fusion bonded epoxy coating for long life corrosion protection. Straight through full bore to avoid debris traps, small flow resistance.

2、 Ductile Iron Wedge inside and outside fully rubberized with vulcanized EPDM or NBR ,suitable for potable water.

3、 Rubber bonnet gasket for longevity and protection of bonnet bolts, Isolated fasteners for corrosion protection.

4、 Stainless steel stem with rolling thread for high strength and corrosion resistance**.

5、 Back sealing facility to allow for replacement of seals under full operating pressure.

6、 Lower thrust washer to reduce friction.

7、 Ductile Iron Gland Thick Wall Casting, replaceable O rings.

8、 Dust Guard to prevent impurities from entering the stem sealing system.

9、 Brass bushing for alignment, low torque operation.
