TRANSFER LINE VALVE Metal seated, parallel slide gate valve with substituting ring
Design Our TLV03 Transfer Line Valve is designed to : ◘ Avoid operating troubles related to coke deposits on sealing surfa- ces and in dead spaces. ◘ Prevent « sticking » troubles caused by the introduction of coke solids into the lower part of the valve body. ◘ Benefit from a longer life without maintenance.
