Director, Engineering Manager said:
The PRVs we used in the beginning were always having trouble and were nothing but a big headache for us. The set pressure would quickly rise, so it was necessary to perform adjustments daily, and when even that didn't work, we were forced to disassemble the PRVs themselves. Removal of the diaphragms revealed that they were corroded, and we ended up having to replace them every year. On top of that, all the PRVs were installed at high elevations, so working on them involved a great deal of time, effort and money.
That was when we decided to give TLV's COSPECT® a try, after which all the problems we had been having simply disappeared.
In particular, when we changed from a fire-tube type boiler to a once-through type, we had lots of trouble with non-TLV PRVs. COSPECT®, however, has been operating continuously for the 10 years since then, and has had absolutely no need for maintenance.
It has been 18 years since we first started using COSPECT®, and there is simply no substitute for the sense of security that COSPECT® has given us.
