B166 Automatic Dual-Purpose,
By-Pass Valve
A combination by-pass valve and
priming valve specifically designed for small cylinder-filling-type pumps, especially of
the regenerative turbine type, such as the Corken Coro-Flo pump series. The
patented vapor elimination system keeps liquified gas pumps primed to increase system
reliability and decrease pump and seal wear. The B166 is a smooth operating by-pass
with moderate pressure build-up. The B166 is typically used on cylinder filling
pumps as well as aerosol propellant feed pumps.
T166 Pump Flow Control
Valve
A high-pressure
build-up valve for smooth-acting flow control. Specifically designed for by-pass
protection for pumps in the 30-100 gpm (6.8-22.7 m3/hr) range, such as those
used on delivery trucks. In contrast to the B177, the T166 valve opens gradually as
pressure builds up to modulate flow, by-passing the excess capacity smoothly and silently
back to the supply tank. A continuous internal bleed in this valve assists in
eliminating vapors. The T166 is typically used on large capacity pumps filling
variable size tanks and bottles such as those used with delivery trucks or multi-spot
cylinder filling plants.
B177 Differential
By-Pass Valve
A low pressure build-up
by-pass valve specifically designed for applications requiring protection for positive
displacement pumps in the 40-350 gpm (9.1-79.5 m3/hr) range. It can also
be used as a differential back-pressure valve to assure adequate pressure on meters,
etc. To properly function, this valve requires a pressure sensing line from the
storage tank. The B177 is typically used in liquefied-gas bulkplant installations
for the loading and unloading pumps.
