kunkle safety valve catalog factory

Kunkle delivers quality products from cryogenic to high temperature and vacuum to high pressure Steam, Air, Gas, and Liquid applications. Kunkle Valve provides code certifications that meet various global standards such as ASME, PED, CRN, TU and Chinese as well as non-code requirements.

Kunkle Relief Valve OverviewWhen it comes to industrial and commercial safety and relief valve products, Kunkle’s valve’s catalog is second to none in steam, air, gas, and liquid applications.

Kunkle relief valves range in size from ¼” NPT to 6” flange and are suitable in cryogenic and high temperatures up to 800°F environments at vacuum to 7,500 psig pressure. Kunkle Valve’s code certifications meet several global and national board standards, including ASME Section I, Section IV, and Section VIII, PED, CRN, TU and Chinese, as well as non-code requirements.

Relief Valves for Steam ServiceSteam supplies heat for industrial and chemical processes and also is used to heat buildings, supply mechanical energy, and drive mechanical equipment. Steam moves from the boiler to the end point, then heats by direct heating or indirect heating through a heat exchanger. Kunkle steam relief valves are critical to protecting equipment such as boilers, steam lines, and pressure valves, from being over-pressurized.

Relief Valves for Air ServiceKunkle designs valves for air service, for example for air compressors in mechanical shops and small factories where either low-pressure or high-pressure air is required. NASVI stocks Kunkle relief valves for air service in iron, steel and bronze for a variety of uses.

Relief Valves for Liquid ServiceKunkle also makes valves for liquid service, which provide bypass relief in a variety of applications and liquid types.

More About KunkleKunkle Valve is a renowned pressure relief valve manufacturer. Erastus B. Kunkle invented the safety valve to prevent overpressure in locomotive engines. Kunkle patented it in 1875. Since that time, Kunkle has earned its reputation for high-quality valves, and other equipment manufacturers ship their products with Kunkle’s valves pre-installed.

NASVI has stocked Kunkle safety relief valves since we opened in 1975, so we are confident when we call ourselves Kunkle safety valve experts. Every day we fulfill orders for our customers looking for Kunkle relief valves for steam, air, gas, and liquid applications.

Kunkle relief valves are available for ASME Section I, Section IV and Section VIII services with relief capacities certified by the National Board. In addition, Kunkle offers a range of non-code products and each valve, both code and non-code is set, tested, and retested to the customer’s specifications and then sealed at the factory to prevent tampering. Flotech is a Kunkle valve distributor.

The plate mounted on the side of your Kunkle valves is small yet mighty — it’s full of concise information that can help inform your next purchase decision or develop plans for new processes. But like most data snapshots (think the jargon on your “About this Mac” or “About my PC” window), it’s not always clear what everything means.

The ASME stamp is typically in the top corner of your nameplate. This stamp means that the valve has been assembled and set to meet the standards of a specific ASME code section. In this example, the valve has a “V” stamp. That indicates the valve is certified for an ASME Section I application.

Some Kunkle valves are non-coded by design, often for liquid applications that don’t require an ASME certified valve (e.g. Models 19, 20) or for vacuum service (Model 215V).

On the top of your nameplate, you’ll notice an NB stamp, which is associated with theNational Board of Boiler and Pressure Vessel Inspectors. If your pressure relief valve bears the NB stamp, it means it has a relief capacity certified by the NBBPVI in accordance withNB-501. Most Kunkle valves have certified capacities.

Often located near the top of the plate, and in this example, directly to the right of the NB stamp, you’ll notice the manufacturer and assembler name. This particular valve has been set by the factory, which makes Emerson (“EMRN”) the assembler.

Note: The value directly below the product and manufacturer names beginning with “CRN” is the Canadian Registration Number and will not be present on all Kunkle Valves.

Your valve’s nameplate also contains the model number, which is extremely useful for when you need to reorder the same valve. In this case, the model number is6010HGM01. The first two to four digits are generally the series or model the valve belongs to — here,6010.

In most cases, the letter indicating service will be somewhere further along in the model number. However, this letter could be in various positions depending on the valve series, making it tricky to recognize. For the most accurate information, check the product catalog of your valve series.

The size on the nameplate will tell you the nominal pipe diameter of the inlet (the connection on the bottom of the valve), which is 1 ½” in the case of this valve.

To the right of the size on this nameplate is the set pressure, which is 150 psig (pounds per square inch gauge). So in this pressure relief valve’s case, it will open as soon as it detects 150 psig at the inlet of the valve.

On Kunkle nameplates, the rated capacity is abbreviated as CAP. This value needs to meet or exceed your required capacity. In other words, the valve you purchase must be able to relieve pressure at least as quickly as your system’s worst-case overpressure scenario can generate it.

Knowing what all of these values and stamps mean is incredibly helpful when you’re reordering the same part. In most cases, you can just provide your distributor with the model number and be on your way!
