Model 10 Pneumatic Pressure Regulator
Brand: Fairchild Industrial ProductsThe Rotork Fairchild Model 10 is a precision pressure regulator designed for applications that require high performance and accurate process control.
Stability of regulated pressure is maintained under varying flow conditions through the use of an aspirator tube which adjusts the supply valve in accordance with the flow velocity.
The Model 10 features control sensitivity of 1/8" water column and a balanced supply valve to deliver consistent and reliable precision accuracy to maintain your desired set point regardless of supply pressure changes or conditions.
The Fairchild Model 10 pressure regulator will handle a 500 psi, 34 BAR, maximum supply pressure and offers nine (9) output pressure ranges from 0-2 psi, 0-0.15 BAR, 0-15 kPa, up to 5-400 psi, 0.3-28 BAR, 35-2,800 kPa.
The Model 10 precision regulator offers 40 SCFM, 68 m³/hr flow capacity.
Typical Part Numbers are 10212, 10222, 10232, 10242.

The Model 10 Series regulator use the force balance principal to control the movement of the Valve Assembly that controls the output pressure.
When the regulator is adjusted for a specific set point, the downward force of the Range Spring moves the Diaphragm Assembly downward. The Supply Valve opens and allows air to pass to the Outlet Port. As the set point is reached, the downward force exerted by the Range Spring is balanced by the force of the downstream pressure that acts on the Diaphragm Assembly. The resultant force moves the Supply Valve upward to reduce the flow of air to the Outlet Port.
Outlet pressure is maintained as a result of balance between forces acting on the top and bottom of the Diaphragm Assembly.
