For
decades, industry has been living with sub optimal transfer
valves as a means to control fluid flow through redundant filters
and coolers. These cast plug valves had two primary drawbacks,
frequent leakage to the offline vessel and extremely difficult
operation. Despite the presence of several competitive vendors,
the traditional designs went unchanged for years.
This set the stage for HYCOA to revolutionize
the transfer valve back in 1980 with our patented resilient
seal shoe. For the first time, "Zero Leak" and "Transfer
Valve" became terms that could be used together.
This new and innovative approach to an old problem offered
industry additional advantages. Features such as zero frictional
drag during changeover and a positive mechanical lock down
device have turned the JR-33 into a favorite of design and
maintenance engineers as well as plant operators.
Of course, success breeds imitation and several other new
transfer valves have sprung up in recent years. However,
our patented design is still the only one with retractable,
fully covered elastomer shoes. This feature is important
to reduce operating torque. The retraction feature also avoids
dragging an o-ring seal around the valve body bore and causing
potential seal wear or damage.
Past, present and future, HYCOA's commitment and focus
is with the customer who requires top performance from their
transfer valves. We understand the requirements of duplex
filter systems, heat exchangers and other critical API auxiliary
lube oil systems. We also understand the requirements of
our customers who simply want top performance in their transfer
valve.
