applications

- Suitable for all types of nuclear reactors (submarines, scaled down reactors, experimentaal reactors, PWR, CANDU, PHWR, HTGR)
- High and low pressure overpressure protection on liquid, steam, gas, and steam/water mix
- Small capacity, high speed pressure transient
- Primary coolant safety valves for submarines
- Experimental reactors coolant overpressure protection

features

- Excellent operation irrespective of the type of fluid: steam, gas, liquid or two-phase
- Leak tightness up to the set-pressure maximises ageing of the mechanism
- Non-flowing pilot valve minimises ageing of the mechanism
- Accuracy of pilot set pressure opening value with repeatability better than 1%
- Soft opening/closing decreases the loads to the installation
- Low or high pressure in-situ test during operation for preventative maintenance
- Maintained stability even when flow capacity is well below the maximum rate
- Reduced maintenance
- Proven and accurate repeatability and reliability
- K1 - 1 E qualified for applications within the containment area of nuclear plants
