A manifold assembly for a manifold system for fluid delivery comprising: i. a first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] positioned near a fluid inlet, said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] comprising at least two Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] arranged in parallel; ii. a second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)] connected in series with said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)], said second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)] positioned near a fluid outlet and comprising at least two Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)] arranged in parallel; iii. a plurality of first isolating valves [(I1-I2, I4-I5), (I1-I6)], each of said first isolating valves [(I1-I2, I4-I5), (I1-I6)] coupled to each of said Solenoid Operated Valves (SOVs) [(V1-V2, V4-V5), (V1-V6)], each first isolating valve [(I1-I2, I4-I5), (I1-I6)] adapted to facilitate hot swapping of associated Solenoid Operated Valve [(V1-V2, V4-V5), (V1-V6)]; iv. at least one first shuttle valve [, (S4-S6)] connected between said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] and said second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)]; and v. at least one redundant shuttle valve [, (S4'-S6')], characterized in that, said redundant shuttle valve [, (S4'-S6')] is configured to provide redundancy to said first shuttle valve [, (S4-S6)] in a way that the flow of a fluid is facilitated from each Solenoid Operated Valve of said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] to each Solenoid Operated Valve of said second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)], thereby improving the system availability. i. a first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] positioned near a fluid inlet, said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] comprising at least two Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] arranged in parallel; ii. a second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)] connected in series with said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)], said second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)] positioned near a fluid outlet and comprising at least two Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)] arranged in parallel; iii. a plurality of first isolating valves [(I1-I2, I4-I5), (I1-I6)], each of said first isolating valves [(I1-I2, I4-I5), (I1-I6)] coupled to each of said Solenoid Operated Valves (SOVs) [(V1-V2, V4-V5), (V1-V6)], each first isolating valve [(I1-I2, I4-I5), (I1-I6)] adapted to facilitate hot swapping of associated Solenoid Operated Valve [(V1-V2, V4-V5), (V1-V6)]; iv. at least one first shuttle valve [, (S4-S6)] connected between said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] and said second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)]; and v. at least one redundant shuttle valve [, (S4'-S6')], characterized in that, said redundant shuttle valve [, (S4'-S6')] is configured to provide redundancy to said first shuttle valve [, (S4-S6)] in a way that the flow of a fluid is facilitated from each Solenoid Operated Valve of said first set of Solenoid Operated Valves (SOVs) [(V1-V2), (V1-V3)] to each Solenoid Operated Valve of said second set of Solenoid Operated Valves (SOVs) [(V4-V5), (V4-V6)], thereby improving the system availability.
