Dresser-Rand introduces Magnum valve for reciprocating compressors
With precision guided valve elements and springs, the Magnum valve increases the reliability of moving parts for long-term operation. Also, Andrews said, this common design element for all valves minimizes the number of replacement parts required, increasing interchangeability and cost effectiveness.
According to Andrews, the Magnum valve's unique sealing element overcomes limitations of traditional designs. Traditional poppet and plate designs, he said, use geometries that are subject to bending under normal operating conditions.
This bending induces tensile stresses in the element that can lead to fatigue failures under certain circumstances. And because of this, Andrews said, Dresser-Rand designed the Magnum valve element so that the stresses are compressive, rather than tensile.
An added benefit of the Magnum valve is the proprietary Dynamic Valve Analysis (DVA) software used to custom-design every Magnum valve. Andrews said the DVA software allows Dresser-Rand engineers to design the valve to meet specific application requirements.
By taking the basic pattern of the valve and machining it to any size and configuration, cost and cycle times drop because it takes less time to design and manufacture.
