GOYEN "DD" SERIES GENERAL PURPOSE DIAPHRAGM VALVES
Goyen's "DD" Series valves provide the same efficiency and reliability as their "T" Series with a double dresser compression coupling that provides quick, simple installation. These valves can be operated by either integral pilot solenoids (CA Models) or remote pilot solenoids (RCA Models).
Constuction : The "DD" Series valves have bodies, cover, seal retainer and compression couplings manufactured of pressure die cast aluminum. General purpose diaphramgs are made of Buna-N reinforced with nylon mesh. For high temperature applications, Viton kits are available (see below).
Please note: The CA/RCA20DD and CA/RCA25DD valves are no longer available and have been replaced by the Series 4 RCAC20DD and RCAC25DD valves. The repair kits for the older valves are still readily available. See the Series 4 Valve Page for information and pricing on the new 3/4" and 1" valves.
