PCT No. PCT/JP94/00639 Sec. 371 Date Dec. 18, 1995 Sec. 102(e) Date Dec. 18, 1995 PCT Filed Apr. 18, 1994 PCT Pub. No. WO95/28590 PCT Pub. Date Oct. 26, 1995A valve body has second output ports defined in an upper surface thereof. To the second output ports there are selectively and detachably attached quick-connect-and-disconnect pipe couplings or a pipe adapter which provides communication between the second output ports and front output ports through output passages. When the quick-connect-and-disconnect pipe couplings are attached, output pipes can be connected to the valve body from its upper side through the quick-connect-and-disconnect pipe couplings. When the pipe adapter is attached, output pipes can be connected to the valve body from its front side through quick-connect-and-disconnect pipe couplings connected to the front output ports.
