Warren Rupp 095-106-551 Main Air Valve Body

The Warren Rupp 095-106-551 main air valve body serves as the central air distribution component in Sandpiper S-Series air-operated double diaphragm (AODD) pumps. It directs compressed air to alternate sides of the diaphragm chamber, enabling continuous suction and discharge cycles. Constructed from corrosion-resistant polypropylene (PP), this valve body withstands aggressive chemical environments and abrasive slurries common in industrial fluid transfer applications. It features precision-machined air passages and pilot valve ports to ensure consistent shifting signals and minimal air consumption. Designed as a direct drop-in replacement for Sandpiper pump models S05 (1/2 inch), S07 (3/4 inch), and S10 (1 inch), it restores original flow rates and cycling reliability without modification.
