  • Valve facing for sliding valve elements or the like
    Patent number: 4303223
    Abstract: An improved valve facing for one member of relatively sliding gate valve members. More specifically, the improved valve facing has foamed polymeric core and an impervious and solid polymeric outer surface. This combination provides the necessary resilient and deformable characteristics for effecting a long-life seal between the sliding members of the gate valve. When the valve is a drain valve of a fire hydrant most unexpected results are obtained.
