Total price
A closing motion that repeats identically keeps wall thickness inside tolerance. This pilot-operated proportional directional valve in size 25 delivers 325 l/min nominal flow at 350 bar from a pilot circuit kept apart from the main one.
Advantages
- 325 l/min nominal flow at 350 bar for fast closing motion as well as opening motion.
- External pilot oil supply plus external return keep pilot pressure constant.
- Analog ±10 V command value at the on-board electronics, no separate amplifier required.
- Concealed auxiliary actuation for mould changes together with setup work.
- 20.18 kg, FKM seals, HL hydraulic fluid, UKCA evidence.
