Maintenance:
The trap-free internal lines of the Hydraulic
Cleanflow Valve reduce the amount of product residue to a minimum.
When cleaning, a steam lance penetrates right through to the interior
from the outside of the tank to the pressure plate and inlet
flange. During maintenance of the pressure plate and seal, the
valve can be locked in the open position before working on the
valve. All main seals are standard sizes and are easily available
worldwide.
Operation:
The valve is hydraulically operated and has a
1/8" NPT connection. An indicator finger shows the valves
open / closed position. The valve functions to a maximum hydraulic
pressure of 1740 PSIG. In the event of a failure in the supply of
pressure, the valve can be operated by use of a 1" wrench on the
location provided on the handle. The spring loading of the valve
pressure plate ensures that the valve is securely close when the
hydraulic pressure is reduced.
Performance:
The bore is totally unrestricted which, together with
the lack of spring cage internally, gives a much cleaner flow
rate. The discharge rate of the valve under gravity is 132 U.S.
Gallons / Minute and gives a flow equivalent to that of a 4"
conventional style Hydraulic Valve.
