Parallel Slide Gate Valves
For those applications when large temperature variations are expected or fast shutt-off is required, this is the most ideal design. The seats are parallel and the disc has no contact with the seats during the stroke of the valve. Only at the end of the stroke the disc mechanism ensures the contact between seats and disc.
