The next im ortant feature of my present invention resi es in the means for'detachably connecting the parts of the casing-and locking the valve seat in place. The preferred form contemplates the use of a single U-shape bolt 2 3 passed diagonally beneath the casing part 2 (see Fi s. 1, 2 and 4) with its threaded ends extende through apertured lugs of casing part 1, nuts 24 being secured on such ends. One such bolt so passed diagonally is sutlcient, and for the purpose of bracing it and preventing any possibility of deiiection, the lower semi-cylindrical'portion of casing part 2 is formed with beveled ribs 25v against the opposite faces of which ribs the bend of the -bolt is designed to bear.- These ribs radiate from the axial center of the lower casing part, and widen as they extend outwardly. They are out4 of line with each -other so that a bolt may rest against their opposed faces. In this way the pressure of the U bolt is applied directly to the center of the lower casing part (see Figs. l Iand 4) serving thereby to draw the two parts together uniformly, and preventing unequal binding of the valve seat. By this means the valve seat is so firmly held between the two sections that its peripheral portions 10 and lugs 9 on the casings may be dispensed with, as in Fig. 9. But if for any reason it be desired to employ two U-bolts, the single bolt may be removed and two bolts substituted, in which event they are arranged transversely of the valve casing. These are shown in Fig'. 3. Or, the single bolt may be passed in either direction, instead of that shown in Fig. 2, since -the upper casing part is formed with four apertured ears 27. Hence I employ two sets of beveled ribs25 on the underside of the lower casing part. When access is desired to the interior of the valve it is only necessary to remove the sin le U- bolt, or the two U-bolts if two be emp oyed, whereupon the valve seat and the valve may be readily withdrawn and either or both secured in a vise to permit of the filing of the faces thereof. Another advantage residing from the use of the single bolt, passed diagonally of the valve casing, is that it permits the inlet and outlet branches to be placed at right angles to. each other, and furthermore jury thereto. It will also be seen that'by v means `of the two-part handle'the j valve mayy y be locked when opened and'also locked when moved in either direction for closin or cnt- 'v ting ott communication between the inlet and outlet branches, thereby avoidin all danger of accidental opening of the va vev as when' the engine or other machineA is undergoing inspection or repair.

I claim as my invention: i

1. A valve having its casing formed in eparate parts or sections, the opposite parts `ein a U- olt arranged diagonally of one of the casing parts and rigidly casino' part. e l

2. -valve having its casing formed yin separate parts or sections, the opposite parts having lateral branches, one part having apertured lugs and the other beveled lribs radiating from its axial center, and a U- shaped bolt arranged diagonally ofthe casing and engaging the opposite faces `of said ribs, and nuts for securing said bolt to said ears.

3. 'Ihe combination with the casing hav ing a diaphragm provided with lugs or stops on its upper face, of a removable valve seat designed to be supportedby said diaphragm and havin means for engaging said lugs or stops, sai means permittin said va ve seat to be held while being lied or ground. f
