Features and Benefits

The automatic flow control valve is factory set to a rated flow, and shall automatically control the

flow to within 10% of the rated value over a 40 to 1 differential pressure, operating range (2 to 80

psid

). Operational temperature is rated 40-200°F.The valve body is constructed from hot forged

brass UNS C37700 per ASTM B-283 latest revision.

The ball valve is constructed from forged bronze with brass ball construction. It is rated from fluid

40-200°F. Valve bodies are suitable for 400 PSIG, with a working pressure rating per ASTM A53B

threaded joint type. A pressure/temperature test port is provided for verifying the pressure

differential and system temperature.

All supply and return hoses are equipped with swivel end connections. All end connections are

permanently crimped to meet state pressure ratings.

1/2-inch to 1 1/4-inch hose material is EPDM rubber, and rated for maximum working pressure of

400 PSI (1/2-inch), 400 PSI (3/4 to 1 1/4-inch), 400 PSI (1 1/2 and 2-inch).The minimum burst pressure

is four times the working pressure.

Hose material is stainless steel braid over an EPDM liner, and bonded to the braid. Hoses are rated

for 40-225°F.

Hose connector s are permanently crimped. Swivels shall be BP with a male NPT. Adapters are fixed

male NPT. All connections are brass and have reusable thread sealant pre-applied to the tapered

pipe threads.

1½” and larger hose materials are a single stainless steel braid over a corrugated type 321 stainless

steel tube, butt welded to carbon steel end fittings. Operational temperature are rated from 25°F-

225°F.

Hoses are rated for a minimum working pressure of 400 PSI (1½”), 400 PSI (2”). Minimum burst

pressure is four time the working pressure.

TheY-ball strainer body is constructed of bronze with a brass cap.The cap is sealed with a non

asbestos gasket.The strainer body is suitable for 400 PSIG, with a maximum pressure rating of 400,

at 150°F WOG. Working pressure rating is Class 125.The strainer screen is 304 stainless steel with

20-mesh (½”-1¼”).The strainer is ported with female pipe thread per ASME/ANSI b1.20.1, and

B31.9.

The motorized water valve is a 2-position, spring-return water valve installed on the return side of

the system.The valve will open when the unit compressor begins running to allow water flow

through the unit. As the compressor shuts down, the valve will slowly close off water through the

unit to reduce water consumption.

At low differential pressure the flow area required to achieve higher flow can exceed the flow area available for the respective series.

Therefore, the minimum pressure differential requirement is increased for the higher flow ranges of each series Mesurflo valve.
