A riser for a surface irrigation system has a housing and an outlet valve. The housing has an open upper portion and an outlet defining an orifice. The valve includes an upper closure, a valve member, and an actuating lever. The upper closure is securable to the riser. The valve member is coupled to the closure and mountable within a flow path of the fluid, the valve member operable for opening and closing the valve, and configured to seat against a valve seat of the housing, and on an upstream side of the orifice, whereby the pressure of fluid within the valve urges the valve member against the seat when the valve is closed. The pivotable actuating lever having one end extending through the orifice and coupled to the valve member, and an operable end for operating the valve member to open and close the valve.

Various embodiments of an antimicrobial insert for a stopcock medical connector are provided. More specifically, the present invention relates to an antimicrobial insert that is seated within at least a portion of the annular bore of the connector's tap, wherein fluid within the annular bore contacts the antimicrobial insert, thereby preventing microbial proliferation within the stopcock medical connector.

A ball valve system includes a body having an upstream end and a downstream end and a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position. The ball valve assembly includes a stem movable in an actuation direction substantially parallel to the vertical axis, the stem including a recess at a proximal portion of the stem, a guiding member extending within the recess of the stem, the guiding member being configured to prevent rotation of the stem or cause rotation of the stem, and a lubrication port in fluid communication with the recess.

A pressure regulator valve adapted to be secured within a container housing a beverage to be dispensed through the aid of pressure within the headspace (11) above the beverage, the regulator valve includes a housing (16) containing a piston (26) having one surface exposed continuously to the pressure in the headspace and the other surface being engaged by a spring (44), a source of pressurized gas (14) such as carbon dioxide is secured to the housing and includes a valve (60) which is activated by the piston which moves responsive to a differential between the spring force and the headspace pressure to open the valve (60) when the headspace pressure falls below a predetermined level to insert the carbon dioxide into the headspace to maintain the headspace pressure sufficient to dispense the beverage.

Various embodiments of an antimicrobial insert for a stopcock medical connector are provided. More specifically, the present invention relates to an antimicrobial insert that is seated within at least a portion of the annular bore of the connector's tap, wherein fluid within the annular bore contacts the antimicrobial insert, thereby preventing microbial proliferation within the stopcock medical connector.

A ball valve system includes a body having an upstream end and a downstream end and a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position. The ball valve assembly includes a stem movable in an actuation direction substantially parallel to the vertical axis, the stem including a recess at a proximal portion of the stem, a guiding member extending within the recess of the stem, the guiding member being configured to prevent rotation of the stem or cause rotation of the stem, and a lubrication port in fluid communication with the recess.

A valve assembly including a valve having an opening and closing mechanism for controlling the flow of a fluid through the valve controlled by an actuator and an actuator mounting bracket secured to the valve. The actuator mounting bracket includes upper and lower clamps securing the valve actuator to the valve regardless of the valve position.

The invention provides a cable drive device (10) including a linear drive member (12), and a cable drum (14) attached to a support bracket (30, 32) adapted to be affixed to a surface. The cable drum (14) has an axle (26) supported by the support bracket (30, 32) to allow rotation of the cable drum (14). The cable drum (14) has a cable (42) affixed at either end of said linear drive member (12) and tautly wrapped around the cable drum (14). The cable drum (14) is located between the ends of the linear drive member (12) to, in use, allow the linear drive member (12) to be guided through the bracket (30, 32) to move the linear drive member (12) longitudinally when the axle (26) is rotated.

A shuttle valve for a safety valve arrangement is provided with a valve housing (2), which includes a fluid inlet (4) and two fluid outlets (6, 8). A movable shut-off body (12) is arranged in the valve housing (2) and can be moved between two closure positions, in which the movable shut-off body (12) closes one of the fluid outlets (6, 8). The shut-off body (12) is arranged in a pivotably about a pivot axis (D). The shuttle valve includes a linear drive (46) which is coupled to the shut-off body (12) in a manner such that the shut-off body (12) is pivotable between its two closure positions by moving the linear drive (46).

A butterfly valve assembly includes: a butterfly element configured to control fluid flow through a main conduit; and a butterfly controller configured to control the butterfly element. The controller includes a first chamber for receiving fluid at a first pressure, a second chamber for receiving fluid at a second pressure, and an actuator responsive to the first pressure and the second pressure. The assembly also includes a relief valve arranged to regulate the first pressure in the first chamber within a predetermined pressure range, wherein the relief valve comprises an adjustment mechanism for adjusting the predetermined pressure range. The butterfly valve assembly may comprise a manual override operable to lock the butterfly element in a fully open position or a fully closed position.
