T
he Aerodyne pneumatic pressure regulator, Model 9021, reduces high
inlet pressure (10,000 psi) to a precise output pressure in a small,
lightweight design. This cartridge style regulator contains a small internal
“pilot” valve that precisely controls the dome pressure of the valve’s main
poppet. This design allows for minimal overshoot while maintaining quick
valve response.
Fluid flow is directed through the main orifice, allowing for large fluid flow
rates and precise pressure control. During pressurization, the main poppet
remains closed until the “pilot” valve increases the dome pressure. When
the specified outlet pressure (dome pressure) is achieved, the main poppet
starts to open.
Preset outlet pressure regulation set point (non adjustable) assures
accurate installed performance. Metal seat design assures excellent
performance and durability. The cartridge design allows for greater system
integration yielding a smaller overall package.
