Valves supply refrigerant on fish processing ship
Grenco selected Flowserve Worcester V-Flow control valves and series 44 three-piece ball valves to control the supply of CO2 refrigerant to 36 Optimar vertical plate freezers.
CryoService, a major distributor of CO2 and other gases to the fast food industry, worked in conjunction with Flowserve Flow Control to find a solution to the problem.
CryoService was already using the Worcester Controls' 44 Series as part of a handheld manifold block at the end of the CO2 feed line.
The company wanted to install a nonreturn valve as close to the supply nozzle as possible but did not want to significantly increase the weight of the manifold.
The solution was to use the Worcester NR44 that combines the standard Worcester three-piece valve with a Gestra nonreturn valve into a single, compact lightweight assembly.
The combination of the two products is unique and combines the positive shutoff that is required with assurance that there can be no reverse flow back to the supply vessel.
