140 Series Proportional Pressure Control Valve
Brand: IMI NorgrenProportional current to pressure closed loop converter, intrinsically safe with ATEX, FM and CSA approvals.
Fail safe operation so that in the event of a control signal failure output pressure falls to zero. Ideally suited to process control applications in hazardous environments where certified products are required.
Features- Advanced Electronic Control
- Explosion Proof / Intrinsically Safe / Type nA nL
- Complete Electronics Modularity for Ease of Maintenance
- Jack Socket for On-Site Monitoring
- Fail-Safe (unit pressure falls to zero on signal failure)
- Field Replaceable Filter
- Weatherproof (IP66 or Type 4X)
- High Performance and Accuracy
- Fast Response and Minimal Temperature Effect
- Large Flow Capacity
