New Blockbody POSV for high back pressure
To secure an injection system, a customer of LESER needed a POSV that could secure a process with 200 bar-g design back pressure at a set pressure of 207 bar-g. This is four times more than the standard API 526. LESER engineers solved this with a block body design that can withstand the high outlet pressure.
This is because the standard cast bodies are not designed for these high back pressures. In order to prove that the valve bodies manufactured for the first time comply with the regulations, tests were carried out on the LESER water test bench.
This approach expands the LESER POSV portfolio and makes it more flexible for different requirements.
