Industrial S-45 Water Valve Solenoid AK Solenoid Valve

The Invensys S-45 water valve solenoid is an industrial general‑purpose valve that uses an electric coil to actuate a water passage, enabling automated on/off control in process and equipment systems. This AK‑design variant is associated with 240V operation in catalog listings (notably the S-45 with K-62687-33) and is part of Invensys’ general-purpose water valve family alongside related S-45 parts such as K-62687‑42. Designed for general water service, the S-45 regulates flow in industrial lines when paired with an appropriate controller and power supply. Because coil voltages and fittings vary by sub-model, the exact specifications depend on the exact part number (K-62687 series) and should be matched to your installation.
