    Abstract: An actuator for actuating a valve from a first position to a second position includes a housing and a rotatable stem mounted within the housing and restricted from moving axially. The actuator also includes a non-rotatable plunger engaging the stem such that the plunger moves axially in response to rotation of the stem, whereby the valve is actuated from the first position to the second position. The actuator is also provided with a non-rotatable indicator member, which is mounted within the housing and through which the stem extends. The indicator member engages the stem such that the indicator member moves axially in response to rotation of the stem. A viewing window is formed in a wall of the housing such that the indicator member can be seen through the window for indicating the first position and the second position of the valve.

    Abstract: A sealing ring for use in connection with a filter bag assembly of a filter is disclosed. The sealing ring includes an annular body having an outer annular wall projecting from the body. The outer wall is flexible such that it can engage an adjacent surface of the filter in a liquid-tight manner for forming a seal between the surface and the sealing ring.

    Abstract: A holding device for a filter element is disclosed. More particularly, the holding device includes a body having upper and lower surfaces. The lower surface is sized and shaped so as to engage an end of an associated filter element. The holding device also includes a compressible member, which is positioned on the upper surface of the body, and a connecting mechanism for directly and movably connecting the body to a body of at least one other identical holding device.

    Abstract: A swing check valve, which is adapted for automatically inhibiting back flow of fluid from an outlet thereof to an inlet thereof, includes a clapper member and a housing. The housing has a first body portion, which includes its own valve seat and its own mounting mechanism adapted to removably mount the clapper member therefrom when the first body portion is positioned adjacent to the inlet of the valve. The housing also has a second body portion, which includes its own valve seat and its own mounting mechanism adapted to removably mount the clapper member therefrom when the second body portion is positioned adjacent to the inlet of the valve. The first and second body portions are removably connected to each other in an end-to-end fashion and are interchangeable with each other, whereby each body portion may be utilized as a replacement for the other body portion.

    Abstract: A device for controlling fluid flow through a conduit includes a ball valve with a ball having a conduit terminating at an end thereof in an outlet orifice having a non-circular shape. The orifice shape is compound and may be selected to linearize the flow/ball angle relationship. The ball may be reversible to permit reversing the flow change dynamic and may also be a flow reducer.
