Kelso’s new JS330 external constant-force spring pressure relief valve (EPRV) for Pressure Tank Cars was successfully pressure and flow tested and confirmed by an independent, AAR-approved engineering test facility in Nunn, Colorado, as required by the railroad industry.
The JS330 represents Kelso’s entry into the high-pressure and performance products strategy. The JS330 is a derivative of Kelso’s existing EPRV patent and meets the performance specifications and regulatory requirements for pressure tank cars. It is designed for demanding applications in the transport of pressurized commodities such as propane and anhydrous ammonia.
Kelso has applied to the Association of American Railroads for an application number and service trial approval. The service trial is expected to commence in late 2013 and complete in two years.
The JS330 will be offered in 225PSI, 247PSI, 280PSI and 330PSI ratings. It is suitable for applications in both the new tank car and retrofit/repair markets.
