Industrial high pressure hand valve

An industrial high pressure hand valve that provides a completely positive shutoff comprising:

• a valve body;
• a handle grip;
• a live swivel;
• a hose barb;
• a nozzle;
• wherein the valve body is comprised of a handle attached to the valve body via a coiled pin, a stem, a stem adapter, a stem spring, and a retaining ring which retains the stem within the valve body;
• wherein said valve body is further comprised of an internal bore to allow for the flow of media through the valve body, internal threads located at the inflow and outflow ends of the valve body for connecting of said handle grip and nozzle thereto, a metallic ball contained within a ball receiving bore of the valve body which includes a recessed portion for when the valve is in an open position and the metallic ball is unseated, a seat insert, and seat insert O-ring;
• wherein said seat insert has a diameter that is slightly larger than the diameter of a seat insert receiving portion of the valve body so that an interference fit must be used to install the seat insert and seat insert O-ring;
• wherein said interference fit is achieved by cooling the seat insert and seat insert O-ring to a temperature sufficient to shrink said seat insert and seat insert O-ring slightly and by heating the valve body to a temperature sufficient for said valve body to expand slightly;
• said seat insert and seat insert O-ring are press fitted into the receiving portion of the valve body and once the temperature of all said seat insert, said seat insert o-ring, and said valve body returns to ambient temperature, said interference fit has been achieved;
• wherein said stem is slidably connected to the valve body via the stem adapter and the retaining ring and sealed against media leakage via the use of a stem o-ring;
• wherein said nozzle is comprised of the nozzle for either air media or liquid media;
• wherein said valve body, handle grip, live swivel, hose barb, and nozzle all contain an internal bore or passageway to allow for the flow of media therethrough;
• wherein said valve body, handle grip, live swivel, hose barb, and nozzle are threadably connected.
