Abstract: A ball valve in which cams (82, 84) are mounted on the ball member (34) to engage spring biased seat rings (30, 32) and cam the seat rings to a retracted position at which the seat rings are retained. The ball valve has a removable cover plate (16) so that the ball member (34) and seat rings may be subsequently removed from the valve body (12) while the valve remains in-line. A removable stop (56) engages and blocks rotation of the ball member past its fully opened and fully closed positions and the cams (82, 84) engage the seat rings only after the stop is removed and the ball member is rotated past its normal stroke and beyond fully opened or fully closed positions.

Abstract: An adjustment device for liquefied gas lighters is disclosed, which allows precise automated setting of maximum and minimum permitted flame heights during the assembly of lighters which have a rotatable valve adjustment member extending from a valve well in the lighter. Fixed stop means are provided on the lighter. An adjustment mechanism rotates with the valve adjustment member and after adjustment of the flame height, movable stop means are formed in the adjustment mechanism in positions chosen such that the movable stop means can abut the fixed stop means at positions of the adjustment mechanism corresponding to maximum and minimum flame height, respectively.

Abstract: An improved sanitary diversion valve is disclosed which provides a better seal to plastic sanitary pipe, is corrosion resistant, has an improved valve core retention mechanism, and a sealed access to prevent leakage and tampering. A resilient O-ring core retention mechanism maintains the core in close contact with the housing without being susceptible to corrosion. Plastic coupling rings are molded into the inlet and outlet ports of the housing to enable high integrity seals to be formed with plastic sanitary pipe connecting therewith. In addition, a plastic coupling ring is molded around the core shaft port in the housing to enable sealing a plastic sanitary pipe thereto as an access tube to the valve. The resulting improved sanitary diversion valve is easily fabricated, easy to install, provides a high integrity seal with plastic sanitary pipe connecting thereto, is reliable for withstanding corrosion of its moving parts during a long term of operation, and is leakage and tamper proof.

Abstract: A diverter valve, particularly adapted for use in septic systems, for controlling the flow of effluent from a septic tank to a plurality of leach beds, comprising a thick-walled valve body of cast urethane having a deep circular groove in the upper surface to receive a section of a capped pipe to afford access to the valve control from ground level, and having a centrally and vertically disposed valve chamber provided with an inlet port and a plurality of outlet ports, rigid integrally cast webs extending from the top to the bottom walls of the valve body dividing the same into separate inlet and outlet chambers communicating with the central valve chamber, oppositely disposed circular openings in the top and and bottom walls of the valve body, the walls of the openings providing bearing surfaces for a tapered valve plug of cast urethane having top and bottom circular sections and having a cut-away central section providing a passageway for alternatingly connecting the inlet port with one of the outlet ports.

Abstract: A liquid or fluid-flow control valve of four-part construction is shown having a longitudinally extending, open-end housing within which a plug-like stationary seating part is centrally positioned to direct fluid flow between end and side-positioned inlet and outlet portions of the housing and as controlled by a rotatable stem part having a sleeve portion that is positioned concentrically about the seating part. The stem part projects through one end of the housing and has a side port that is moved into and out of alignment with a side port in the seating part. The seating part is provided with an obliquely-positioned ringlike sealing gasket, and the stem and the seating parts are removably mounted within the housing part by an end-positioned cooperating bonnet part.
