Technical Overview
Gate Valves with Open/Close Indicator are designed for liquid flow on/off service where the valve position needs to be visible during operation.
This valve type is part of the rubber wedge gate valve range and is available in normal and anti-corrosion Series F4 and Series F5 versions from DN50 to DN200.
Technical Overview
The main function of this valve is opening or closing the flow path. The open/close indicator provides a visible indication of the valve position, allowing the operator to check whether the valve is in open or closed condition.
According to the catalog, this valve is available in both normal and anti-corrosion versions. The final valve configuration should be selected based on the required Series F4 or Series F5 design and the operating conditions of the line.
Available Versions
- Normal Series F4 and Series F5 versions
- Anti-corrosion Series F4 and Series F5 versions
- Size range from DN50 to DN200
Function
The valve is used for liquid flow on/off service. It is selected where the required operation is to open or close the pipeline flow path, while also providing visible open/close position information.
Open/Close Indicator
The open/close indicator is the defining feature of this valve type. It allows the operator to identify the valve position visually instead of relying only on the operating mechanism.
Selection Notes
Selection depends on the required nominal size, Series F4 or Series F5 configuration, and whether the application requires a normal or anti-corrosion version.
If the line condition involves corrosive liquids, the anti-corrosion version should be reviewed according to the catalog information for anti-corrosion rubber wedge gate valves.
Technical Summary
Gate Valves with Open/Close Indicator are rubber wedge gate valves used for liquid flow on/off service where visual valve position indication is required. The catalog lists this model in normal and anti-corrosion Series F4 and Series F5 versions, available from DN50 to DN200.
