The Benefits of the MSV-100® Control Valve

What is the MSV-100® Control Valve?

The DFT® model MSV-100® control valve is a flanged medium service control valve available in the 600, 900, and 1500 class range that can handle a wide variety of fluids, including gases, liquids and steam. In addition, this valve can withstand high pressures up to 3700 psig and temperatures up to 1,000°F

DFT® has manufactured world-class valves for over 75 years. The following blog and video provides an overview of the MSV-100® control valve along with its features, benefits, and common applications.

The MSV-100® features an inline straight-thru venturi flow design which is cavitation resistant. Here you see pressurized upstream fluid filling the pipe, seating the ball, and achieving FCI 70 Class V type shutoff:

As the MSV-100® valve opens, the fluid jet impinges upon the downstream replaceable liner which is hardened to prevent excessive wear. As a result, thru-body wear does not occur.

The DFT® MSV-100® is a position seated design and the control element is a ball that is guided by the cage that positions it relative to the downstream seat by means of linear stem travel. The flow characteristic of the DFT® control valve is essentially linear over the complete stroke as shown here:

At the intermediate position where the valve is designed to throttle, the MSV-100® provides fine modulating control.

As the valve fully opens, it operates as a true venturi that can handle high-pressure drops. In the fully open position, if the fluid cavitates, this will occur in the mid-fluid stream, away from the valve body and pipe walls. The MSV-100® features trim that is easily replaceable on the bench and requires no special tools. This minimizes maintenance, downtime, and lowers the overall cost of ownership. Various trim sizes are available depending on the required flow capacity.
