How should an electric forged steel ball valve be selected? The key factors include valve construction, process medium, pressure, temperature, nominal size, and electric actuator torque matching. USA VTON electric forged steel ball valves combine forged steel ball valve construction with electric actuation for industrial pipelines requiring remote shutoff and automated control.
1. Select Materials According to the Medium
The first step is to identify the process medium, such as water, oil, gas, or industrial process media. Medium temperature, pressure, corrosiveness, and the presence of particles should also be considered.
The valve body, ball, stem, and sealing components should be selected according to actual operating conditions. For high-temperature, high-pressure, or corrosive applications, material and sealing compatibility should be confirmed based on the specific process conditions.
2. Determine Valve Size According to Pressure and Pipe Size
The valve DN size should match the pipeline and flow requirements. The pressure rating should cover the actual operating pressure while also considering operating temperature.
For frequent operation or high differential pressure, valve operating torque becomes particularly important. The electric actuator should provide output torque appropriate for the actual valve load, with reasonable engineering allowance.
3. Select the Electric Actuator According to Control Requirements
For full-open/full-close operation, an on-off actuator can be considered. When continuous valve-position adjustment is required according to flow, pressure, or temperature, a modulating actuator should be selected.
Power supply, electrical interface, control signal, position feedback, operating time, and installation space should also be confirmed. USA VTON can configure the electric actuator according to the automation requirements of the application.
Application Example
At a certain industrial high-pressure pipeline, remote process-media shutoff was required. The technical team evaluated the medium, pipe size, operating pressure, and temperature before selecting the forged steel ball valve and matching the electric actuator to the required operating torque. Opening direction, limits, and feedback status were then checked during commissioning.
Selection Advice
For technical confirmation, prepare the medium, DN size, pressure, temperature, connection type, control mode, power supply, and operating frequency. Complete information allows USA VTON to configure the electric forged steel ball valve according to the actual application.
