Abstract: A distribution valve for directing high pressure coolant to various stations of a metalworking machine or similar device. A hollow shaft directs high pressure fluid to an aperture in a seal plate. The aperture is selectively coupled to one of several seals mounted in a housing. Each seal is formed with an axial passageway for directing fluid to its respective station when aligned with the aperture. A biasing means holds the seal against the seal plate to provide a leak free interface.

Abstract: Gate valve means connected in a waste pipe system have a hollow housing with an inlet and an outlet connected to the waste pipe system. A blade is disposed in the housing at a substantially right angle to the waste pipe system and is selectively movable between a closed position blocking the inlet from the outlet, and an open position allowing waste flow between the inlet and outlet. The blade moves between the open and closed positions and a pair of seals are disposed in the housing in an abutting relationship aligned to receive the blade therebetween when in the closed position and to seal waste flow between the inlet and outlet from the interior of the housing when the blade is in the open position. Each of the pair of seals has a unique design enabling it to mechanically rotate with the blade, thereby limiting wearing forces thereon.
