Pressure Relief Valve
Marotta Model PRV95

The Marotta PRV95 high-performance pressure relief valve eliminates premature wear and instability associated with conventional relief valves. The PRV95 provides stable operation using upstream control for valve positioning. The result is a highly dependable relief valve with excellent repeatability and minimal lag time.
 

The design is unique in its ability to maintain a seal near the set point of the relief limit. Typically, relief valves seal tightly up to 90 percent set point and then reseat when pressure is reduced to 85 percent of set point. The PRV95 maintains seal integrity until 98 percent of set point and will reseat at 95 to 97 percent of set point. This allows the operator to protect a system without exceeding its limits.

The Marotta PRV95 offers several advantages over conventional relief valves:

• Smooth transition from fully closed to fully open

• Noise and wear reduction through elimination of chatter

• Decrease in the risk of product fire and explosion in oxygen systems through elimination of hard impacts

• Reductions in the uncontrolled venting of hazardous fluids and products

The increased stability of the valve operation results in better performance, with wider operating ranges and control. All of these attributes translate into the additional advantage of lower life-cycle costs.
