There are industrial process control applications where it can be beneficial to operate valve actuators with pressurized water instead of compressed air. There are instances, common at remote sites, where compressed air is not available, but mains water supply in the pressure range from
60-100psi (4 - 7 bar) is present. Standard HYTORK XL Actuators have been used successfully in water applications but the manufacturer recommends that their XLW Actuators, specifically designed for water operation, are
used in this application to assure smooth and reliable operation. Specialties of the XLW series address concerns with corrosion protection, bearings and preventing ingress of particulates with the water. Contaminated water can cause
damage to the actuator seals and bearing areas, reducing operating efficiency and actuator life.
