Description

The 3251 flow control is an ideal solution to cylinder speed control where space is at a premium. Costly fittings, connections and piping expenses can be eliminated because the valve can rotate 360 degrees, and the piping alignment can be in any direction. The 1/8" model can be rotated after final assembly. The 3251 Flow Controls are standard male to female ported and can be ordered with optional Prestolok fittings in place of the female port. This allows for quick connection and eliminates the need for separate tube fittings. Flow is adjusted with an allen wrench and locked with a nut for tamper protection.
