Abrasive Metering Valve, FSV
Details
The FSV, an original Clemco design, is the tried-and-true workhorse of the industry. It is among the most imitated Clemco components.
Easily set the abrasive flow without tools by adjusting a single lever. The steel metering plate inside this valve can wear on the left or the right side, giving you twice the lifespan before replacement is required. An inspection plate on the back of the valve alows for a view inside the valve without removing it from the blast machine.
This valve is not recommended for use with steel grit or steel shot.

Frequently Asked Questions
The choke valve is the ball valve in the pusher line below the machine. In normal blasting it stays fully open — the handle aligned with the piping. Closing it while blasting drops the pusher-line pressure below vessel pressure, which forces abrasive down through the metering valve. That makes it useful for exactly two things:
- Clearing minor blockages, such as damp abrasive: rapidly open and close the choke valve several times while blasting.
- Rapidly emptying the machine of abrasive at the end of the day.
