Goyen's Aluminium Valve Outlet Coupling (VOC) has been designed to lock 1" & 1 1/2" blowtubes to Goyen's 25 & 45 FS diaphragm valves. These products are designed for simple installation to the blowtube and slide outlets of the FS valve.
The Aluminium VOC is assembled to reverse pulse 25 & 45 FS valve outlets and blowtubes used in fabric filter baghouses. The VOC product locks the pipe in place in the valve outlet.
The two halves of the VOC are clamped tight onto the schedule 40 blowtube, while retaining lugs of the VOC locate onto the FS slide outlet. |
