Technical Overview
Extended Stem Gate Valves
Extended Stem Gate Valves are designed for installations where access to the valve is difficult or where a manhole or basin is not available.
This valve type is part of the gate valve range and is available in normal and anti-corrosion Series F4 and Series F5 versions from DN50 to DN300. The stem length can be produced according to customer requirements.
Technical Overview
The main purpose of an extended stem gate valve is to allow valve operation when the valve body is installed in a location that is not easily accessible.
According to the catalog, this valve can be used for buried or direct-buried installation. The extended stem arrangement allows operation from an accessible point while the valve remains installed below ground or in a difficult-access location.
Applications
- Installations where access to the valve is difficult
- Locations without a manhole or basin
- Buried valve installations
- Direct-buried valve installations
Available Versions
- Normal Series F4 and Series F5 versions
- Anti-corrosion Series F4 and Series F5 versions
- Size range from DN50 to DN300
- Stem length according to customer requirements
Design Purpose
The extended stem is used when the valve operating point needs to be moved away from the valve body. This allows the valve to be opened or closed without direct access to the installed valve body.
The catalog describes this configuration for cases where access limitations make standard valve operation difficult.
Selection Notes
Selection depends on the required nominal size, Series F4 or Series F5 configuration, installation condition and whether the application requires a normal or anti-corrosion version.
For buried or direct-buried installations, the required stem length should be defined according to the installation depth and customer requirements.
