Post yard hydrant with controlled adjustable flow

A method of operating a hydrant comprising a valve housing defining a longitudinally extending conduit having an upstream end and a downstream end;

• a nozzle in fluid communication with the upstream end;
• an operating rod disposed in the conduit for longitudinal reciprocation therein, the rod having a plunger end and a driving end, the plunger end disposed within the conduit and adapted to prevent flow of fluid through the conduit from the upstream end to the downstream end in a first position, and permit flow through the conduit in a second position, a flow rate of fluid through the conduit is dependent based upon a longitudinal position of the plunger relative to the conduit;
• a handle pivotally coupled to the valve housing and coupled to the driving end of the operating rod;
• and an adjustable stop coacting with the handle and operatively coupled to the handle, the adjustable stop being a linkage coupling the handle to the operating rod, the method comprising:
• adjusting the adjustable stop to a desired position;
• and
• pivotally rotating the handle relative to the valve body until the handle comes into contact with the adjustable stop, thereby causing the operating rod to move in a longitudinal direction relative to the conduit,
• wherein the adjustable stop limits the pivotal rotation of the handle and, in turn, limits the longitudinal movement of the operating rod, thereby limiting the second position of the operating rod.

A modification kit for a hydrant comprising a valve housing defining a longitudinally extending conduit having an upstream end and a downstream end;

• a nozzle in fluid communication with the upstream end;
• an operating rod disposed in the conduit for longitudinal reciprocation therein, the rod having a plunger end and a driving end, the plunger end disposed within the conduit and adapted to prevent flow of fluid through the conduit from the upstream end to the downstream end in a first position, and permit flow through the conduit in a second position, a flow rate of fluid through the conduit is dependent based upon a longitudinal position of the plunger relative to the conduit;
• and a handle pivotally coupled to the valve housing and coupled to the driving end of the operating rod, whereby pivotal movement of the handle relative to the valve body causes the operating rod to move in the longitudinal direction relative to the conduit, the modification kit comprising:
• a first slot link and a second slot link, each slot link comprising a first end, a middle portion and a second end, the first end adapted to be operatively coupled to the operating rod, the middle portion including a hole adapted to register with holes of ears of a head section of the valve housing, and the second end including at least one opening;
• and
• an adjustment arrangement adapted to be positioned through the at least one opening in the second end of the first slot link and the second slot link.
