Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...

Abstract: The paper presents a mathematical model of a piston compressor which is a part of an oxygen gas generator. Taking into account the structural parameters of the compressor, as well as the ...

Zahroof Valves (ZVI) is always looking for new and unconventional ways to solve old problems. The company, founded in Houston in 2010, has developed an innovative reciprocating compressor valve ...

Many service technicians experience service calls where the compressor has both a low head pressure and a high suction pressure. Often, the refrigeration equipment is still running, but the product ...

Abstract: This paper presents a novel approach to diagnosing faults in reciprocating compressor valves. Based on easily available vibration data, a transformation to a high-dimensional vector space is ...

The problem: A piston-type reciprocating compressor has had valve damage, or the valves just are not sealing for some reason. This low-temperature refrigeration system has a thermostatic expansion ...

The award-winning StraightFlo valve from Zahroof utilizes a revolutionary design with a straight through flow path that reduces compressor power, increases throughput, extends run time, reduces ...
