Technical specification

The KFL-B type ball valve consists of a 2-part body. Up to nominal width DN 100, the flange is screwed into the body. From nominal width DN 125, the two body parts are flanged together. The stem is blowoutproof and from nominal width DN 32 is provided with a two-fold O-ring seal. It is possible to attach the actuators from DN 32 via the standard ISO flanged connection.

Please ask separately, where requirements exceed the standard conditions of use listed in this data sheet. As a matter of principle, the operating and maintenance instructions, in particular the safety instructions must be observed!
