Reliable Isolation on a Small Footprint

The 08.1 Insertable Gate Valve is designed to be installed directly between two connecting pipes without flanges. The advantage: It requires very little space.

The gate valve uses VAT's patented VATLOCK technology. It ensures a reliable gate sealing without any friction. In addition, the VATLOCK technology mechanically locks the gate in the closed position on both sides of the valve. This allows flexible and reliable use of the 08.1 FV Insertable Gate Valves in a wide variety of application situations and, in the case of pneumatic actuation, offers additional safety in the event of a compressed air supply failure.

In its modular design and its various design options, the 08.1 can be adapted to almost any application. 

Already installed in thousands of demanding applications, the 08.1 has proven its outstanding reliability under a wide range of process conditions.

08.1 FV Insertable Gate Valve

08.1 FV Insertable Gate Valve - Closed
08.1 FV Insertable Gate Valve - Open

The 08.1 FV Insertable Gate Valve is available as manual or pneumatic version, with solenoid valve either as on board solution or for external mounting. Standard voltage of solenoid valve is 24 VDC, but other voltages are available on request. The 08.1 series uses a push rod in the manual version and is available in DN 63 - 100 mm (2.5”- 4”).

The gate position is indicated visually (mechanically) directly on the valve by means of a position indicator and is also output as an electrical signal. Standard sealing material is FKM, other materials are available on request.
