M1' The balanced telescopic piston steam valve will not warp with high tempera--5 turcs and is easily lubricated. Steam is admitted through the interior oi the J," valve, passing in at the center and out through ports near the ends. Exhaust mu: is by the ends of the valve, reducing the pressure on the valve stem packing.,1: The governor automatically varies the position of the high pressure cutofi if and proportions the speed of the compressor to the demand for air. 2"; These and other features of design and construction are responsible for the an, marked steam economy of "XPV" compressors. Their steam consumption:, _@ is equal to that of a full Corliss compressor of the same size and more than:1"! one-third less than that of a unit equipped with flat steam valves and J; throttling governor. "1' Operating engineers approve of their enclosed construction, automatic lubri11' cation and freedom from vibration. I ii: "XPV-1"--Duplex steam and Duplex air cylinders...show more
