Model descriptions
Features
Model 910: Carbon Steel (CS) body and
bonnet with Stainless Steel (SS) trim.
• Available with soft seats.
Model 911: All SS construction.
Model 916: Same as model 910 resilient
seat/seals. Superior “leak-free”
performance.
• Threaded cap standard (back pressure
tight). Maximum back pressure 50 psig
[3.4 barg].1
• Hex on valve nozzle provides for easy
installation.
Model 917: Same as model 911 except
resilient seat/seals. Superior “leak-free”
performance.
• Warn ring offers easy adjustability.
Model 920: Steel body and bonnet with
screwed cap and stainless steel spring for
organic fluid vaporizers (ASME Section I “V” Special Use or application).
• Guide to nozzle ratio reduces friction.
Model 921: Steel body and bonnet with plain
lift lever and stainless steel spring for forced
flow steam generators (ASME Section I - “V”
Special Use or application).
Model 927: Steel body and bonnet with
packed lift lever and SS spring for high
temperature/pressure hot water boilers
(ASME Section I - “V” Special Use or
application).
• Pivoting disc design offers exceptional
seat alignment.
• Valve bodies are heavy duty casting.
• Full nozzle design for optimum flow
performance.
• Threaded side outlet for piped off
discharge to eliminate fugitive emissions.
• Each Kunkle valve is tested and inspected
for pressure setting and leakage.
Model 910
Applications
• Air/gas compressors, intercoolers,
aftercoolers.
• Liquid filled pressure vessels/systems,
ASME Section VIII (UV).
• Process and industrial corrosive
applications.
Code:
• Pressure vessels - containing gas, air,
liquid or steam, including tanks and
receivers.
Note:
• Overpressure relief and protection of
pumps, tanks, lines and hydraulic systems.

• All SS Model 911 may be suitable for
sanitary/edible applications.
• Vacuum systems including pumps, tanks
and equipment.
• Oil/gas separators.

1. Back pressure increases set pressure on a one
to one basis, and reduces capacity. Back
pressure in excess of 10% of set pressure is not
recommended.

MODEL 900
Models 912, 913, 918 and 919 ASME Section VIII, Air/Steam/Gas/Liquid, “UV” National Board Certified.
Also available for Vacuum Service.
PED Certified for Non-Hazardous Gas.
Model Descriptions
Features
Model 912: Full nozzle design. Stainless
Steel (SS) warn ring and disc with
brass/bronze base. Bronze/brass body
and bonnet.
• Available with soft seat.
Model 913: Full nozzle design.
Bronze/brass body and bonnet. 316 SS trim
(base, disc and disc holder).
Model 918: Same as model 912 except
resilient seat/seal. Superior “leak-free”
performance. FM approved with 316 SS base
for fire pump installations in “BDD” and
“BDE” sizes2.
Model 919: Same as model 913 except
resilient seat/seal. Superior “leak-free”
performance. Bronze body and bonnet.
316 SS trim (base, disc and disc holder).
• Threaded cap is standard (back
pressure tight).
• Hex on valve nozzle provides for easy
installation.
• Warn ring offers easy adjustability.
• Pivoting disc design corrects
misalignment and offers exceptional
performance.
• Guide to nozzle ratio reduces friction.
• Full nozzle design for optimum flow
performance.
• Threaded side outlet for piped off
discharge to eliminate fugitive emissions.
Model 912
Pressure and Temperature Limits
Applications
Models 912, 918: – Steam
• Air/gas compressors - intercoolers aftercoolers.
• Liquid filled pressure vessels/systems ASME Section VIII (UV).
• Pressure vessels - containing gas, air,
liquid or steam. Including tanks and
receivers.
• Vacuum systems including pumps, tanks
and equipment.
• Optional materials for low temperature cryogenic applications.
• Oil/gas separators.
• Overpressure relief and protection of
pumps, tanks, lines and hydraulic systems.
• By-pass relief or pressure regulation.

Maximum back pressure 50 psig [3 barg] threaded cap and packed lever3
Notes:
1. ASME standard valves for air or steam service
must have lift lever. For steam boilers and
generators.
3. Back pressure increases set pressure on a
one to one basis, and reduces capacity.
Back pressure in excess of 10% of set
pressure is not recommended.
2. Requires variations listed below for adjustable
relief pressure settings:
Variation 10: 60 - 125 psig [4.1 - 8.6 barg],
Variation 11: 125 - 175 psig [8.7 - 12 barg], or
Variation 12: 176 - 250 psig [12.1 17.2 barg]

Notes:
1. No code stamp or “NB” on nameplate below
15 psig set.
2. See Specifications Table (pages 3 and 9) for
Pressure and Temperature Limitations.
3. Liquid conversion factors to determine liquid
capacity at other than 10% accumulation,
multiply by the following:
1.022 = 15% accumulation
1.045 = 20% accumulation
1.066 = 25% accumulation (see page 20)
