■ Maximum operating pressure = 350 bar.
■ Maximum valve leakage at 24 cSt = 0,07 cc/min.
■ Area Ratio: A3 to A1 = 1.8:1; A3 to A2 = 2.25:1.
■ Pilot passage into valve = LOEC-Z, LOFC-Z: 0,9 mm; LOGC-Z, LOHC-Z: 1,50 mm.
■ Pilot volume displacement = LOEC-Z, LOFC-Z: 1,1 cc; LOGC-Z, LOHC-Z: 4,1 cc.
■ The position switch confirms that poppet is in the spring biased closed position.
■ Switch specifications: supply voltage: 20-32 V DC; Maximum output load: ≤ a400 mA, duty ratio 100%.
Turn on time: ≤ a25 ms.; Operating temperature range: -25 to 80° C. See the Sun website for complete
switch specifications.
