Xactrol® Control Valve

Characterized and stacked disc trim Leak-free isolation and control in one
Size : 1/2" – 36” ANSI/ASME
Class 150 - 2500 Integral, characterized downstream seat Upstream disc inserts for modulation.
The Xactrol® product group couples ValvTechnologies’ zero-leakage technology with special designs that allow rotary modulating control. From the Mark I’s design that features a characterized upstream seat to the Mark III’s precision engineered stacked disks, the Xactrol® allows the customer to combine precise flow control with tight shut-off. The Xactrol® is typically used in applications where minimum flow and relatively high differential pressures are required.


Mark I Design
• Designed for minimum/normal flow control conditions
• Variety of characterized upstream seats available
• Engineered to meet your control needs

Applications
The Mark I is designed for high-pressure and/or erosive services. Applications include: vents, drains and blow downs among others.


Mark II Design
• Designed for minimum/normal flow control conditions
• Variety of characterized upstream seats available
• Engineered to meet your control needs
• Includes a second flow port designed to handle continuous minimum flow conditions

Applications
The Mark II is designed for high-pressure and/or erosive services with the addition of a required continuous minimum flow. The valve features an additional flow port through the ball for continuous flow applications. Applications include: boiler drum and continuous blow down valves.


Mark III Design
• Designed for minimum/normal flow control conditions
• Variety of characterized upstream seats available
• Engineered to meet your control needs
• For applications requiring very high-pressure drops
• Includes a series of upstream pressure reducing plates
• For the most difficult control applications

Applications
The Mark III is designed for high ΔP liquid applications where cavitation and flashing are a concern and for high ΔP gaseous applications where fluid is flowing at sonic velocity. Applications include: boiler feed pump re-circulation and bypass.
