Modular valve assemblies are disclosed. In embodiments the modular valve assemblies include a first frame and a second frame. The first frame includes a fluid inlet and first mount, and the second frame includes a fluid outlet and a second mount. A connection element extends between the first mount and the second mount. At least a first modular block and a second modular block are disposed on the connection element and position between the first and second frame. The first and second modular blocks may each be rotatable about the connection element between a use position and a maintenance position. In the use position, a composite flow path extends from the fluid inlet, through a first fluid flow path in the first modular block, through a second fluid flow path in the second modular block, and to the fluid outlet. Rotation of the first or second modular block to its maintenance position moves the first or second fluid flow path, respectively, out of the composite flow path.

Temperature control device (1) has a hot water inlet (12), a cold water inlet (14) and an outlet (16) for tempered water. A diffuser (18) is provided in the device (1) to disrupt the flow of hot water after it enters the device (1). The disrupted hot water emerges from the diffuser (18) into a chamber (20) in which it is melded with cold water that is able to enter the chamber (20) from the inlet (14) when a piston (22) is spaced from a seat (24). The melded hot and cold water result in tempered water that is discharged from the outlet (16). A temperature sensitive device (26) is provided, which is responsive to changes in ambient temperature. A temperature setting mechanism (52) is provided which is operatively associated with the temperature sensitive device (26) and permits the maximum temperature of the discharged tempered water to be adjusted.

A valve cartridge (1) having a body (10), a piston (12) and a piston support (22). The body has a seat (14). The piston (12) is supported on the piston support (22) and movable between first and second positions. The piston (12) is spaced from the valve seat (14) at the first position and the piston (12) seats on the valve seat (14) at the second position. The piston (12) and piston support (22) form a confined space. The volume of the confined space is at a maximum when the piston (12) is at the first position and is at a minimum when the piston (12) is at the second position. The piston (12) is under bias such that the piston (12) is biased away from the valve seat (14) to the first position and, in use, the piston (12) is able to seat on the valve seat (14) in the second position when subjected to sufficient pressure to counter the bias.

A freeze prevention valve comprising a body having an inlet (14) and an outlet (16) for fluid to exit the valve in an open condition, a valve seat (18) provided adjacent an opening (22) of the valve, a piston member (20) that is movable in the body, the piston member comprising a piston shaft and a piston head (24), the piston head (24) arranged to seat against the valve seat (18) in a closed condition of the valve, a temperature sensing device (26) comprising a temperature sensitive element (28), operatively associated with the piston head (24), wherein the temperature sensitive element contracts and expands when the temperature of the fluid sensed by the temperature sensing device decreases or increases, wherein contraction of the temperature sensitive element allows the return spring (30) to move the piston member to unseat the piston head from the valve seat and thereby open the valve.
A drain valve comprising a body, an inlet for fluid to enter the drain valve, an outlet for fluid to exit the drain valve, a piston member having a piston head and a piston shaft, a seat against which the piston head seats in a closed condition of the drain valve, and a rotatable member that is rotatable relative to the body. The rotatable member is rotatably retained with the piston shaft, such that rotation of the rotatable member in one direction causes the piston member to move in a first linear direction away from the inlet such that the valve head is unseated from the seat to open the drain valve and, in use, allow fluid to enter the drain valve via the inlet and discharge via the outlet. Rotation of the rotatable member in the opposite direction causes the piston member to move in a second linear direction toward the inlet to seat the valve head on the valve seat to close the drain valve and, in use, prevent fluid from entering the drain valve via the inlet.

Hot water storage unit, relief device and method of making a hot water storage unit
A hot water storage unit 100 having a vessel 102, in which hot water is storable, an outer casing 104 enclosing the vessel 102, a hot water outlet 114 for heated water to exit from inside the vessel 102, and a relief device 106. The relief device 106 relieves excess pressure and/or temperature from inside the vessel 102 by allowing water to escape from inside the vessel 102 and exit from the relief device 106. The relief device 106 comprises a housing 108 containing the operational components of the relief device 106. The relief device 106 is removably retainable relative to the vessel 102 such that the housing 108 of the relief device 106 is located substantially behind the outer casing 104 of the hot water storage unit 100 on the inner side 122 of the outer casing 104.
The hot water storage unit 100 can be made by removably retaining the relief device 106 relative to the vessel 102 and placing the outer casing 104 around the vessel 102 so that the housing 108 of the relief device 106 is located substantially behind the outer casing 104, on the inner side 122 of the outer casing 104, after the outer casing 104 has been placed around the vessel 102.
