Valve modification
Thread Content
The manual gate valve with DN450 size on the heat transfer oil pipeline takes a long time to operate and is difficult to control. Consider installing an electric actuator on the valve; this saves labor and allows for quick opening and closing of the valve. Please contact if possible
To install an electric actuator on a DN450 manual gate valve, the following factors must be considered first: 1. **Valve parameters and environment**: Determine information such as the model of the existing gate valve, its pressure rating, connection method (e.g., flange connection), as well as the operating temperature and pressure of the heat transfer oil pipeline. This information helps in selecting the appropriate electric actuator. 2. **Selection of electric actuators**: Choose an appropriate electric actuator based on requirements such as the valve’s opening and closing torque, operating temperature, and control method (local control or remote control). The output torque of the actuator must be greater than the opening and closing torque of the valve to ensure smooth operation. 3. **Supplementary accessories**: Some accessories may be required, such as positioners, limit switches, and manual operating mechanisms (for use in the event of a power failure), to meet operational and control requirements. 4. **Installation and commissioning**: Installing the electric actuator requires professional personnel, and commissioning is needed after installation to ensure good coordination between the actuator and the valve, thereby achieving accurate opening and closing control. 5. **Safety considerations**: As it is a heat transfer oil pipeline, special attention must be paid to fire and explosion prevention; the electric actuators selected should meet the relevant safety standards. Taking these factors into account, it is possible to start contacting professional suppliers of valves and actuators, who will provide more detailed recommendations for selection and installation. If you need further assistance, it is recommended that you contact a professional valve supplier or system integrator in your area; they can provide detailed solutions and support. .
It cannot be installed directly; secondary modification is required. Since the dimensions vary from manufacturer to manufacturer, an on-site measurement is needed to determine the modification plan. Brackets need to be replaced or customized, and in some cases, the valve stem also needs to be replaced.
Install a pneumatic motor in place of the original handwheel; pneumatic power is available everywhere
