SKU: N/A Category:

Series PRA – Air loaded pressure regulator uses the standard air from a compressor instead of a spring to generate the force needed to regulate pressure. Design incorporates a poppet seat, double u-cups, large area rolling diaphragm and one piece body construction. A pressure balanced shaft assures smooth and stable control, while the valve design provides excellent flow performance. A common self-relieving type compressed air valve is needed to connect your compressed air line to the regulator. The PRA will mimic whatever pressure you apply to the top via the self-relieving valve. If you apply 40 psi to the top of the PRA, you can expect downstream liquid pressure to be 40 psi as well.
