Research Control Valves Offer Several Advantages:
1. Compact and lightweight design.
2. Constructed from forged raw materials for exceptional pressure resistance. Disassemblable internal parts reduce maintenance costs, ensuring equipment stability and leak prevention.
3. Electric actuators provide high precision regulation, controlling flow rates for membrane water molecule separation and concentrated water discharge.
4. Mitigation of cavitation, noise, and piping vibration.
5. Labyrinth-type valve cages enable multi-stage pressure reduction, with adjustable ratios up to 100:1. Double sealing prevents external leakage.
