Typical Specifications
Automatic control valves shall have NPT threaded type
fittings, 1/2-inch through 1-inch (15 mm through 25 mm)
sizes, and shall be ANSI rate
d to withstand the pressures and
temperatures encountered. Valves shall have metal-to-metal
seats, stainless steel stems, and Ethylene propylene O-ring
packing. Valves shall be ANSI Leakage Class IV (0.01% of
Cv). Valves shall have a 50:1 rangeability (Cv <1) or better.
All two-way valves shall be provided with equal-percentage
contoured throttling plugs. All three-way valves shall be
provided with throttling plugs such that the total flow through
the valve remains constant (linear) regardless of the valve
position.

angle female, or union male end connections, see Powermite
