Eliminating Cavitation in Dirty Applications

Operators in the oil and gas, chemical industries and power generation, are frequently confronted with extreme pressure differentials in their processes.

Cavitation occurs when the pressure of a process medium temporarily drops below the vapour pressure and then rapidly recovers. Vapour bubbles form as the pressure drops below the vapour pressure and then collapse as the pressure recovers. As a result of cavitation, valve body walls and other components erode, degrading performance and shortening valve life.

To combat this, they need valves with continuous, steady-state flow curves with appropriate flow characteristics, long service life and low maintenance costs.

The Valtek® Multi-Z axial flow control valve eliminates cavitation often associated with high-pressure drops. It is designed to accommodate solids in liquid media, minimize high sound levels, tolerate high temperatures, eliminate cavitation formation and with a variety of materials to resist corrosion.

The Valtek® Multi-Z valve prevents cavitation by:

• Controlling the pressure drop as the process medium is directed through multiple trim stages (i.e., three to six, depending on the application)
• Ensuring the liquid pressure does not drop below the vapor pressure threshold

When the Valtek® Multi-Z first opens, only the first stage opens; all downstream stages are held closed. This allows the seating surfaces to open wide while the pressure drop across the first stage is low, preventing seat damage.

Valtek® Multi-Z valve provides solutions for:

• Applications with large degree of solids while eliminating cavitation
• Cavitation caused by high pressure drop applications
• Unique and complex applications that require specific engineered trims to eliminate cavitation
• Higher rangeability than other convention cavitation solutions

With the Valtek® Multi-Z valve’s ability to accommodate solids in liquid media while minimizing noise and vibration levels by eliminating cavitation, we can help you to optimize the flow, reduce downtime and increase overall process efficiency.
