Numatics FlexiBlok FRL R12 series relieving miniature pressure regulator has measuring range of 0 - 125 psig features 1/4" NPTF connection
Regulators are used to reduce pressure to a required working pressure. They consist of a diaphragm which floats between a main spring (top) and a valve (bottom). By turning the adjustment handle clockwise, the main spring is forced onto the rubber diaphragm which, in turn, is pressed onto the valve stem. When the spring pressure becomes greater than the air pressure in the control chamber below the diaphragm, the valve is forced down and flow begins. As flow continues, the pressure begins to build and air, via the aspirator tube, fills the control chamber and forces the diaphragm upward. As forces balance, the small spring under the valve piston causes the valve to close. The cycle continues in a balanced process of reducing or increasing flow based upon the downstream pressure.
- Locking adjustment knob
- Three different pressure ratings available
- Can be installed as modular or individual unit
