About TV

This is a transmitter isolation valve that can be used on both dry media and liquids. The compact design and unique flange pattern enable direct installation on the tank wall. Any downstream transmitter or any other equipment can be disengaged if needed without draining the tank.

The TV valve is modular designed and it can easily be customized in materials to different process conditions. As standard it is available with a valve body in a stainless steel, but it can also be supplied in Duplex stainless steel. Stafsjö’s retainer ring system offers great flexibility and several seat material options.

Stafsjö’s gland box system with TwinPack braids ensures that no media reaches the surrounding environment. It can also be reinforced with a box bottom scraper for demanding applications.
