Advantages

• External pilot oil supply and external pilot oil return
• Nominal flow 50 l/min against a maximum flow of 170 l/min
• Operating pressure to 315 bar, W6 spool, 3 switching positions
• Concealed auxiliary actuation for commissioning and service moves
• On-board electronics, 4 to 20 mA command value, 24 V DC supply
• UKCA under SI2016/1091, weight 8 kg, NBR seals for HL oil
