MAIN CHARACTERISTICS, SEALS AND FLUIDS - for other fluids not included in below table, consult our technical office
Assembly position Compliance
Ambient temperature
Any position. For AGRLE valves, the drain port Y has to be connected directly to the tank without
counter pressure RoHS Directive 2011/65/EU as last update by 2015/65/EU
REACH Regulation (EC) n°1907/2006 Standard execution = -30°C ÷ +70°C /PE option = -20°C ÷ +70°C
/BT option = -40°C ÷ +70°C
Seals, recommended fluid temperature
NBR seals (standard) = -20°C ÷ +80°C, with HFC hydraulic fluids = -20°C ÷ +50°C
FKM seals (/PE option) = -20°C ÷ +80°C
HNBR seals (/BT option) = -40°C ÷ +60°C, with HFC hydraulic fluids = -40°C ÷ +50°C
Recommended viscosity
