Part 768670A
.
2005 Nordson Corporation
Description
The function of the Pinch Valve Assembly is to reclaim and transport powder
coating materials from a conical surge hopper situated underneath a
cyclone.
See Fig 1
The surge hopper (1) collects the powder which is then pumped by the
Pinch Valve Assembly back to a sieve or other conditioning or storage
equipment.
The assembly consists of two sleeved pinch valves (2) and (3) vertically
mounted above each other in housings, a support frame (4), and a surge
hopper lifting mechanism (5) which forms a seal to the cyclone during
operation. As an option, a vibrator can be fitted to the cone of the surge
hopper to encourage powder to enter the pinch valves.
