(57) The valve housings (12, 14) are formed from solid, metal stock, and are bored through
and tapped to define fluid inlet ports (18) and outlet ports, chambers, and tapped
mounting holes. A cylinder (16) is replaceably fastened between the housings by means
of tie bolts (26) fixed in one of the housings and in penetration of the other. Ends
of the cylinder open onto fluid inlet and discharge, valve-confining chambers. Pulstation
dampener bottles or tanks are removably fixed to the housings for communication with
the inlet and outlet chambers, and admit fluid thereinto, and discharge fluid therefrom,
respectively.
