Included in the price is also a pressure test certificate which is needed to prove its up to its safety function. We have had to have design involvement as the current valves that are installed are the wrong type of valve (Globe valve hard seats) and are passing and causing issues along with operator burden. These Worcester valves are a must for plant to work more efficiently.
