FAQ What is the significance of the ‘B40D7X’ designation in the type number? The ‘B’ indicates the poppet type, ’40’ sets the cracking pressure at 40 bar, ‘D’ specifies NBR seals, and ‘7X’ denotes the component series, which is important for compatibility and service parts. Is this valve suitable for use with hydraulic fluids other than standard mineral oil (HL, HLP)? The ‘D’ designation indicates NBR (Nitrile rubber) seals, which are compatible with mineral oils (HL, HLP) according to DIN 51524. For other fluids like phosphate esters (HFD-R), FKM (Viton) seals would be required. Always consult the datasheet for fluid compatibility. What is the recommended cavity specification for installing this NG40 cartridge valve? This valve is designed for installation in a cavity conforming to ISO 7368. For nominal size 40 (NG40), the specific dimensions for the cavity, including port locations and tolerances, must be strictly followed to ensure proper function and sealing. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
