The electric control gate valve is a motorized industrial valve designed for on-off flow control in pipelines carrying water, oil, gas, or chemical media. It integrates a direct-drive electric actuator with a rising stem gate mechanism, allowing precise opening and closing via external control signals. The valve body is constructed from cast iron or stainless steel, depending on the model, and is rated for pressures up to 16 bar and temperatures up to 150°C.
The actuator supports both 220V and 380V AC power inputs and accepts 4-20mA feedback signals for position monitoring. Control accuracy is specified between 1% and 2.5%, meaning the valve can position within ±2.5% of the commanded opening. The turning angle is adjustable from 90° to 180°, allowing customization for systems requiring partial opening or throttling. The internal gate is hardened to resist erosion and is sealed with EPDM or PTFE depending on media compatibility.
This valve is used in water treatment plants, chemical processing facilities, and oil and gas distribution networks where automated flow control is critical. Buyers include system integrators, municipal utilities, and industrial maintenance departments. Packaging is in wooden crates with internal foam padding. Trade terms typically include FOB Tianjin or CIF port of destination. Lead time is not specified and must be confirmed per order.

Before ordering, confirm the exact valve size, pressure class, and media compatibility with the supplier. Request a material certificate for the gate and stem, and verify whether the actuator is rated for the ambient temperature and humidity of your installation site. Do not assume the 4-20mA signal is pre-calibrated - confirm the calibration procedure and required tools.
Confirm the Incoterms - FOB Tianjin is typical, but clarify whether export documentation, customs clearance, and insurance are included. Lead time is not stated; request a production schedule and shipping window. Payment terms are usually 30% advance and 70% before shipment. Ensure the supplier provides a packing list with serial numbers matching the actuator and valve body.
Upon delivery, inspect the valve for physical damage, moisture ingress, and missing components. Test the actuator with a multimeter to verify signal response and limit switch function. Retain the original packaging for at least 90 days. Request a test report for pressure tightness and torque performance. Without documentation, warranty claims may be invalid.
