Deionizing (DI) water systems remove ionized minerals, salts, and contaminants from water using ion-exchange resins to produce high-purity deionized water. These systems are essential in industries where water quality directly impacts product performance, such as pharmaceuticals, laboratories, food & beverage, electronics manufacturing, and medical equipment cleaning.

Within a DI water system, valves and regulators play a critical role in maintaining stable pressure, controlling flow, protecting resin beds, and ensuring consistent water purity. Reliable pressure and flow control help prevent channelling, resin damage, equipment stress, and fluctuations that can compromise the quality of deionized water.

We offer a wide range of valves and regulators designed for deionizing water systems, including:

Back Pressure Regulators: Maintain constant upstream pressure to protect ion-exchange resin beds and ensure even flow distribution. They help prevent channelling and stabilize system performance during fluctuating demand.
Pressure Reducing Regulators: Provide controlled, consistent downstream pressure to sensitive DI equipment, preventing over-pressurization that can damage resin tanks, filters, or polishing units.
Industrial Control Valves: Deliver accurate flow control throughout the DI water process, including pre-treatment stages, resin beds, rinse cycles, and polishing circuits, to ensure stable operation and maintain consistent water purity.
Globe-Style Cage-Guided Control Valves: Ideal for precise modulation and low-noise performance, these valves provide stable control in DI water recirculation loops, regeneration lines, or high-purity transfer applications.
Wafer-Style Control Valves: A compact option for skid-mounted DI systems. These valves ensure efficient flow regulation in tight piping layouts without compromising accuracy or durability.
Electric Control Valves: Provide automated, precise flow and pressure adjustments based on system demand or purity requirements. Ideal for DI water generators that require consistent, real-time control.
