TI3 Series
The TI3 model really is a unique design. It is designed for shut-off isolation of differential pressure level sensing. Unlike other transmitter isolating valves, which are only adapted from standard knife gate valves, the TI3 model was developed for the sole purpose of isolating the transmitter. The TI3 uses standard 1/2″ socket drive.

Face to face dimension
A unique transverse seal, consisting of a transverse seal profile and packing compound, makes the body bubble-tight towards the atmosphere.
The transverse seal can be repacked at any time and under full pressure using the lateral packing screws.
With its optimized gate geometry, accumulated media is pushed out of the gate guide and flushed out into the bore by the increased flow.
In the closed end position, the gate is also mechanically supported.
Application areas
Pulp and paper industry
e.g. Pulp Stock (Low to high density), Chemical solutions, bleaching agents …

Another success story in wastewater treatment.
This 6” Wey knife gate valve VM with a Rotork motor replaced a defective competitive valve at a wastewater treatment plant in Pennsylvania, USA. Thanks to the proven Wey sealing system, our valves are 100% bi-directional shut off with zero leakage.
Manual operation at 7m (24′) hight
Whenever an applications requires infrequent valve operation, manual operation is the most space-saving and cost-effective solution. Just like at this wastewater treatment plant in the U.S. where our Wey knife gate valves VM can be operated manually at a height of 24’ (7.3 m) thanks to chainwheels connected to the actuator.
System changeover to knife gate valves
These knife gate valves VM DN 4″ were recently installed at a wastewater treatment plant in Ohio, USA. The existing scum system was aging and pumps and valves needed to be replaced. Our Wey knife gate valves were selected due to their resistance to deposition and solids. Compared to the previously installed plug valves, they are also much lighter and therefore easier to handle. The system was commissioned successfully in October.
