Origination

Walter Frank developed PRV9i in response to the demand for a genuine 2½ N.B pressure regulating valve, with the additional benefit of a wider outlet setting range of 3.5 to 9 bar. The design has been developed from the existing Frank Type 3 range of modular PRVs, but with the enhanced outlet setting range. Walter Frank has already supplied the new PRV9i into offshore, petro-chemical sites, as well as for UK building protection contracts.

Walter Frank understands the importance of continued research and development, and is currently researching spring technology to offer even better valve performance.
