a body comprising an inlet, an outlet, and a liquid flow passage that extends through the body from said inlet to said outlet; a valve chamber defined in said body between said inlet and said outlet, said valve chamber located between an inlet portion and an outlet portion of said liquid flow passage, said body defining an upper opening that provides access to said valve chamber; a valve seat located in said valve chamber; a bonnet secured to said body in covering relation with said upper opening, said bonnet including a stem aperture; a valve element for controlling flow of liquid through said valve chamber from said inlet of said body to said outlet of said body, said valve element comprising a valve stem including:
(i) a first portion that is slidably received in said outlet portion of said liquid flow passage between said valve seat and said outlet; and,(ii) a second portion connected to said first portion and extending outwardly through said stem aperture of said bonnet such that an outer end of the second portion is located external to said valve chamber;(iii) a seal located between said first portion and said second portion of said stem; a handle connected to said outer end of said second portion of said stem and adapted for manual movement between first and second positions, wherein:
movement of said handle from said first position to said second position causes movement of said stem from a first stem position where said seal is engaged with said valve seat to a second stem position in which said seal is separated from said valve seat to allow fluid communication between said valve chamber and said outlet portion of said liquid flow passage; and,movement of said handle from said second position to said first position causes movement of said stem from said second stem position to said first stem position in which said seal is engaged with said seat to block fluid communication between said valve chamber and said outlet portion of said liquid flow passage. |
