Import Digital Device, Electrical Ball Valve Actuator — Buy in wholesale FOB from Supplier in China

The Digital Device, Electrical Ball Valve Actuator from Tianjin Bernard Actuator Co., Ltd. is designed for precise control of industrial ball valves using a 4-20 mA DC input signal and delivers a matching 4-20 mA DC output signal. It features a basic error tolerance of ±0.5%, ±1%, or ±2.5%, with deviation controlled within 1.5% and a dead zone adjustable between 0.5% and 3%. The actuator supports dual power supply options: 220 V AC 50 Hz for single-phase and 380 V AC 50 Hz for three-phase systems, and operates with a servo-motor system featuring double protection and high efficiency.

It includes integrated cut-off signal protection, over-torque limiting for bidirectional operation, automatic switching, and dynamic braking to prevent mechanical stress. The unit is built with enhanced electromagnetic interference resistance and meets IP55, IP65, or IP67 protection ratings depending on configuration. Ambient temperature ranges from -10°C to 55°C for integrated models and -25°C to 70°C for discrete units, with humidity tolerance up to 85% RH in non-corrosive environments. These specifications align with standard industrial actuator requirements for control valve automation in chemical and water treatment applications.

This actuator is commonly purchased by manufacturers in oil and gas, wastewater treatment, and process automation sectors requiring fail-safe valve positioning. Buyers typically specify the actuator for use with flanged or horizontal foot-mounted ball valves. Packaging is standard industrial crate with foam padding, and lead time is confirmed directly with the supplier. Trade terms are negotiable but commonly FOB Tianjin, with payment via T/T or L/C. Buyers should verify the exact IP rating and signal tolerance required for their control system before ordering.
