Ringo Valves – Self operated control valves for the Actuators Air Supply Emergency System for Almaraz Nuclear Power Plant

Ringo Valves has concluded the design, manufacturing and testing of Self operated control valves for the Air Supply Emergency System for the actuators of certain critical valves of Almaraz Nuclear Power Plant in Spain:
17 off Self Regulated Control Valves 1 1/2” 900# Material SA182 F316, Nuclear Class NC3 and Leakage Class VI.

These are critical valves since their function is to assure the air supply to pneumatic actuators of certain critical valves of the plant in case of failure of normal supply, taking air for an emergency tank at 1860 psig and providing air to the installation in the outlet set pressure range of 72-115 psig. This pressure range as well as the required flow for the actuators operation is guaranteed provided that pressure at the emergency tank is above 150 psi.
