■ Maximum operating pressure = 350 bar.
■ Maximum valve leakage at 24 cSt = RVCD: 30 cc/min. at 70 bar; RVED: 50 cc/min. at 70 bar;
RVGD: 65 cc/min. at 70 bar; RVID: 80 cc/min. at 70 bar.
■ Control pilot flow = RVCD: 0,11 to 0,16 L/min.; RVED: 0,16 to 0,25 L/min.; RVGD, RVID: 0,25 to 0,33 L/min.
■ Typical response time 10 ms.
■ Factory pressure setting established at 15 L/min.
■ Pressure at port 4 is directly additive to the valve setting at a 1:1 ratio and should not exceed 350 bar.
■ Will accept maximum pressure at port 2; suitable for use in cross-port relief circuits.
