<p>The service valve for isolating the compressor of a chiller system from a flooded evaporator cooler includes a suction pipe (19) mounted in the top section of the evaporator that extends downwardly into the evaporator shell (12) and a shut-off valve (87) mounted inside the shell (12) that is arranged to close against the bottom opening of the suction pipe (19). The valve (87) is connected by a linkage (88) to a shaft (77) that passes through the suction pipe (19) outside the evaporator which when rotated, permits the valve (87) to be opened and closed. <IMAGE></p> |
