The hydraulic winches boast 30, 000lb to 90,000lb of pulling capacity, galvanized steel cable(s), a balance valve
, heavy duty hook, and auto tensioner, making the JP Winch line the only North American company to include such luxuries as standard offerings.
Discharge of material is made via the automatically operated balance valve
at the bottom of the hopper.
According to the Flowserve website, the Flowserve Nordstrom Dynamic Balance valve
is the premier Nordstrom plug valve for crude oil pipelines and other applications which incorporates proven features and user benefits from over 60 years of experience.
The device includes a calibrated balance valve
, a non-slam check valve, and a shut-off valve.
It includes a calibrated balance valve
for flow and a maximum range of control; a non-slam check valve for positive shut-off free of water hammer or valve; and a shut-off valve that includes a calibrated nameplate and memory button so the entire valve can be returned to its initial balanced position after shut-off.
But in this story, we'll show you how to install Delta's two-handled Pressure Balance Valve
(the only two-handled anti-scald one currently available).
This author has used this hybrid design many times, using a single balance valve
in only one location per floor (near the shaft) to balance the flow to that floor, while allowing the self-balancing nature of reverse return to eliminate all the balance valves
at individual coils.
An early concern was that we had too much gas volume between the balance valve
and the fuel injection valve because the balancing valve was located two feet from the fuel injection valve.
The shut-off head reading was taken with the balance valve
fully closed and then used to establish the actual pump impeller size.
