Typical Specifications
Automatic control valves shall have NPT threaded
type fittings, 1/2-inch through 1-inch sizes, and shall
be ANSI rated to withstand the pressures and
temperatures encountered.
Valves shall have metal-to-metal seats, stainless
steel stems, and Ethylene propylene O-ring packing.
Valve shall be ANSI Leakage Class IV (0.01% of
Cv). Valves shall have >50:1 rangeability for Cv
<1and >100:1 rangeability for Cv>1.
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.
For complete technical details on valves with
stainless steel trim, see Powermite 599 Series, MT
Series Terminal Unit Three-way Valves Technical
Instructions, 155-197P25.
Disposal
Do not dispose of valves as household waste.
• Special handling of individual components
may be mandated by law or make
ecological sense.
• Observe all local and currently applicable
laws and regulations.
The actuators are considered electrical and
electronic equipment for disposal in terms of the
applicable European Directive and may not be
disposed of as domestic garbage.
• Dispose of the actuators through
channels provided for this purpose.
• Comply with all local and currently
applicable laws and regulations.
