Sleeve valve with clean out section

A method comprising:

• providing a sleeve valve comprising a sleeve and a gate, the sleeve having an interior surface defining an internal fluid passage, the sleeve including an intake, a discharge nozzle section, and a clean-out section, the internal fluid passage extending downstream from the intake to at least the discharge nozzle section, the discharge nozzle section including a plurality of nozzles, the sleeve being adapted for fluid flow from the intake through the fluid passage and out the nozzles of the discharge nozzle, the clean-out section including at least one access port, the gate being adapted for sliding within the sleeve in sliding sealing engagement with the interior surface of the sleeve between closed, throttling, open, and clean positions, the gate and sleeve being configured and adapted so that the gate, when in the closed position, prevents fluid within the fluid passage from flowing out the nozzles and the access port, the gate and sleeve being configured and adapted so that the gate, when in the throttling position, permits fluid within the fluid passage to flow out some of the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section and others of the nozzles, the gate and sleeve being configured and adapted so that the gate, when in the open position, permits fluid within the fluid passage to flow out the nozzles but prevents fluid within, the fluid passage from flowing out the access port of the clean-out section, the gate and sleeve being configured and adapted so that the gate, when in the clean position, permits fluid within the fluid passage to flow out the nozzles and out the access port;
• moving the gate to the clean position to permit fluid to flow through the access port of the clean out section in a manner to flush debris which is too large to fit through the nozzles of the discharge nozzle section out the access port.

• stopping fluid flow into the intake of the sleeve to prevent fluid from flowing from the fluid passage out the access port of the clean-out section even when the gate is in the clean position;
• moving the gate to the clean position;
• extracting debris, which is adjacent the gate, out the access port.

• a sleeve having an interior surface defining an internal fluid passage, the sleeve including an intake, a discharge nozzle section, and a clean-out section, the internal fluid passage extending downstream from the intake to at least the discharge nozzle section, the discharge nozzle section including a plurality of nozzles, the sleeve being adapted for fluid flow from the intake through the fluid passage and out the nozzles of the discharge nozzle section, the clean-out section including at least one access port, the access port of the clean-out section being larger than any of the nozzles of the discharge nozzle section;
• a gate adapted for sliding within the sleeve in sliding sealing engagement with the interior surface of the sleeve between closed, throttling, open, and clean positions;
• the gate and sleeve being configured and adapted so that the gate, when in the closed position, prevents fluid within the fluid passage from flowing out the nozzles and the access port, the gate and sleeve being configured and adapted so that the gate, when in the throttling position, permits fluid within the fluid passage to flow out some of the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section and others of the nozzles, the gate and sleeve being configured and adapted so that the gate, when in the open position, permits fluid within the fluid passage to flow out the nozzles but prevents fluid within the fluid passage from flowing out the access port of the clean-out section, the gate and sleeve being configured and adapted so that the gate, when in the clean position, permits fluid within the fluid passage to flow out the access port.
