The model 500 is the workhorse of the Wilkins pressure reducing valve line up. The model 500
exhibits the highest flow rates of the entire Wilkins regulator line, making it most suitable for commercial,
industrial, and irrigation applications that demand high flow rates with minimal fall-off. The model 500
is available in 10 – 35 psi, 25 – 75 psi, 75 – 125 psi, and 10 – 125 psi adjustment ranges. All
1/2” to 2”
500’s are equipped with a union inlet and female NPT outlet, while the 2

” and 3” are provided with
female NPT on the inlet and outlet.
Local codes shall govern installation requirements. Unless otherwise specified, the assembly shall be mounted in accordance with the manufacturer’s
instructions and the latest edition of the Uniform Plumbing Code. The assembly shall be installed with sufficient clearance for testing & maintenance.
The Model 500 may be installed in any position. If installed in a pit, vault, or indoors, specify the “SC” sealed cage option. Multiple installations are
recommended for wide demand variations or where the desired pressure reduction is more than 4 to 1 (ie: 200 psi inlet reduced to 50 psi outlet).
CAUTION: Anytime a reducing vale is adjusted, a pressure gauge (Model HGI-25) must be used downstream to verify correct pressure setting. Do not
bottom out adjustment bolt on bell housing.
