Abstract: A backflow preventer assembly for a liquid supply line includes a single unitary valve body including flanged inlet and outlet end openings and a single access opening generally normal to the flow path defined by the inlet and outlet openings. The body houses a pair of check valve seats on opposite sides of the access opening for seating a pair of check valves mounted in series to permit flow from the inlet opening to the outlet openings. Adjustable compression rods interconnecting the two check valves seat the valves against their oppositely facing valve seats. The check valves and compression rods are sized to enable installation and removal of the valves through the access opening. In one embodiment the valve body has a predetermined length for installation in the liquid supply line between a pair of gate valve assemblies, such length being the same as a standard body length for a single check valve assembly.

Abstract: A ball valve structure (10) having a valve seat assembly (46) positioned in annular seat pockets located in a flow passage (14) on opposed sides of a ball valve member (18). Each valve seat assembly is mounted for limited longitudinal movement toward and away from the adjacent ball valve member (18) and spring means (54) are placed within the seat pockets behind the valve seat assemblies to urge the assemblies toward and into intimate contact with the ball valve member. The valve seat assembly includes inner and outer annular concentric seat rings (48, 50) with a resilient sealing ring (52) secured therebetween. The inner annular seat ring has a flared end (64) which fits inside the outer seat ring and energizes or deforms the sealing ring (52) held therebetween, thereby, securely retaining the sealing ring between the seat rings and preventing the introduction of line pressure behind the sealing ring to possibly extrude the sealing ring from its position within the seat rings.

Abstract: A lockable valve having features which impede unauthorized removal of the valve from a conduit to which the valve is connected. The housing of the valve has a passageway. A valve element is movably mounted to the housing for occluding the passageway. A structure operatively associated with the valve element impedes disengagement of the valve from the conduit when the valve element is in a first position. Preferably, the housing of the valve is attachable to the conduit by a fitting which is movably mounted to the housing and such fitting is accessible only through the passageway of the housing when the valve is mounted to a conduit. When the valve element occludes the passageway, it blocks access to the fitting and hence serves as part of the disengagement-impeding structure. The valve may include lugs for connecting the fitting to the housing for movement therewith when valve element is in a second position.
