FEATURES
• Red brass body with NPT-threaded end connections.
• Low seat leakage rate (≤0.05 percent of Cv).
• 50:1 rangeability per VDI/VDE 2173.
• Spring-loaded, self-adjusting packing.
• Accurate positioning to ensure state of the art
temperature control.
• Directly coupled electric and pneumatic actuators for
easy mounting.
• Sizes range from 1/2 in. to 2 in.
• Valve designs provide equal percentage flow
characteristic for water and linear flow characteristic
for steam.
• Stainless steel stem and metal-to-metal seats.
• Repack and rebuild kits for field servicing.

APPLICATION
The V5011N is a two-way threaded globe valve that controls
steam, water, and glycol solutions (up to 50 percent
concentration) in heating or cooling HVAC applications. The
valve is used in two-position and modulating control systems.
The valve is not suitable for combustible gas service.

SPECIFICATIONS
IMPORTANT
The specifications given in this publication do not
include normal manufacturing tolerances. Therefore,
an individual unit may not exactly match the listed
specifications. Also, this product is tested and
calibrated under closely controlled conditions and
some minor differences in performance can be
expected if those conditions are changed.
Models:
V5011N Valve: Two-way threaded globe valve for steam,
water, or glycol. NPT-threaded pipe connections. Throttling
plug provides equal percentage flow characteristic for
water (V5011N1xxx, V5011N3xxx), linear flow characteristic
for steam (V5011N2xxx).
NOTE: V5011N1xxx and V5011N2xxx are direct acting
(stem down to close).
V5011N3xxx is reverse acting (stem up to close).
Dimensions: See Fig. 1.
Valve Sizes and Flow Capacities: See Table 1.
Pipe Connections: Internal NPT-threaded connections.
Seat: Stainless steel, replaceable (except V5011N3xxx 3/4 in.
to 1-1/4 in. which have an integral brass seat).
ANSI Body Class: 150 psi.
Stem: Stainless steel.
Plug: Brass on V5011N1xxx and V5011N3xxx for water;
stainless steel on V5011N2xxx for steam.
Stroke: 3/4 in. (20 mm).
Approximate Leakage Rate: 0.05 percent Cv.
Pattern: 2-way, straight-through.
Body Material: Red brass.
Packing: Spring-loaded, carbon fiber reinforced PTFE V-rings.
Rangeability: 50:1 per VDI/VDE 2173.
Pressure-Temperature Ratings:
Water: 36°F to 248°F, 217 psi (15 bar).
248°F to 337°F, 185 psi (12.8 bar).
Maximum Water Differential Pressure: 230 psid (15.8 bar).
Steam: 100 psi (6.9 bar) at 337°F (V5011N2xxx).
Maximum Differential for Quiet Water Service: 20 psid.
Valve Flow Characteristics:
Water: Equal percentage (V5011N1xxx, V5011N3xxx).
Steam: Linear (V5011N2xxx). See Fig. 2.
Close-Off Pressure Ratings: See Fig. 3, and Table 2.
Valve Design Life: 250,000 full cycles at maximum rated
temperature.
