Inova hydraulic safety manifold blocks are designed for maximum safety and convenience of use. They come with a leakage-free closing of pressure and return lines between the actuator and power pack with a nominal flow of 65/130/250/630 or 1,250 l/min. Other features include:
- Slow pressure build-up phase to carefully fill the hydropneumatic accumulators
- Adjustable pressure dump speed in the turn-off phase (PLc)
- Low-pressure mode with limited oil flow to the actuator (PLc)
- Low-speed mode to ensure safe handling of the piston rod under pressure (flow limiter) (PLc/PLd)
- Slow and bumpless transient from low to high pressure (PLc)
- PLe version with double cartridges with feedback signals for safety SPS (SIV)
- Capability to connect several units together via S stands in sizes 250/500/1250
Manifolds can be delivered in the following versions:
- PB – manifold block for S stands (PLc)
- PBS – self-standing manifold block (PLc)
- SPB – manifold block for S stands with feedback signal (PLd)
- SPBS – self-standing manifold block with feedback signal (PLd)
- SIV – manifold block as a self-standing unit or connected to servo connection plate (PLe)
- S – holder for manifold block PB or SPB
- Sets of accumulators for stands
