Design

• Forged Brass body and SS 304 internal components minimize chances of porosity and corrosion in all conditions and allow easy brazing with copper tubes.
• Spindle with full back seating and special graphite seals allow gland packing to be changed in open position and brazing without disassembling the valve.
Brass body and SS 304 floating internal seat allow metal to metal seating on dissimilar metals resulting in positive isolation and virtually lifelong durability.
