    Abstract: A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

    Abstract: A high purity valve (10) includes a valve body (12) having an inlet (40) and an outlet (42) separated by a valve seat (32), and a diaphragm (22) having a central stem (23) that has a first end coupled to a piston (20) for actuating the valve, and a poppet (28) for engaging the valve seat to close the valve. The poppet forms a dual point seal (50/52, 50′/52′) with the valve seat having at least two points of contact between an annular surface (30) of the poppet and the valve seat. The annular surface of the poppet may be either a concave surface or a convex surface that provides the dual point seal. The valve has a retainer (14) adjacent the diaphragm, and the diaphragm has a flexible web (26) that extends radially outward from the central stem. The retainer has a surface (60) adjacent the web, and the surface is spaced apart from the web such that the web does not contact the surface when the valve is pressurized.
