"rotary gate valve"

The main features of this metal-sealing, single-plate-parallel valve are the precision machined-lipped surfaces of gate and sealing plates, which are floating-mounted, by preapplication with spring-washers.
This system ensures a movement of close-plate over entire swivelling range without gaps.
The totally gapless metal seal prevents penetration of dirt during opening and closing of close-plate.
At the same time a consistant and undamaged sealing surface is preserved which guarantees lasting
operation life.
