- For mixing or distributing of media Controlled by a pilot valve or centrally by a valve island Flow optimised body in stainless steel Long life time and maintenance free operation The Bürkert 3/2way seat valve Type 2006 consists of a pneumatically operated CLASSIC actuator and a 3-way valve body. The actuator is available in two differ ent materials, PA or PPS, depending on the ambient temperature. Interchanging of pressure and working connections enables different fluidic control functions, such as the mixing or distributing of media. The flow-optimised valve body Type 2006 allows excellent flow values. The tried-and-tested self-adjusting pack ing gland secures a high level of tightness and thus ensures reliable operation over years. The 3 way valve Type 2006 is controlled by a pilot valve or by centralised automation using a valve island. It can be equipped easily with electrical position feedback. For the user, the compact Type 2006 is thus often an economic alterna tive instead of two single shut-off valves. Product variants described in the data sheet may differ from the product presentation and description. Type description Can be combined with Type 2006 © Christian Bürkert GmbH & Co. KG, Subject to alteration
