Product Overview

The CLA-VAL D35: Autonomous Electronic Valve Controller is an ultra-low-power electronic valve controller designed to switch one or two latching solenoids based on customizable conditions. It is ideal for controlling valves in locations without electrical energy or where an independent supply from grid power is required. The D35 offers quick and easy commissioning due to its compact and ergonomic design, along with a user-intuitive configuration. It can be configured wirelessly from any smartphone, tablet, or computer via auto-generated WiFi, eliminating the need for cables or special software. Its intuitive user interface provides easy configuration and real-time information. For streamlined deployment, product configurations can be saved and loaded across multiple devices. The CLA-VAL D35 controller comes pre-loaded with customizable condition scenarios suitable for a wide variety of applications, such as 2-stage pressure modulation or flushing valves. Its large internal memory allows for data logging over the product lifetime. Optionally, the D35 can implement data communication through the new generation 4G network (IoT optimized). It can be connected to a custom remote server or interfaced with the CLA-VAL Link2Valves platform for easy, security-proven, and complete integration with full remote configuration.
