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.

Of all the challenges you face keeping your customers’ plants operating at full capacity, safety and relief valves shouldn’t be one of them. NASVI’s job is to give you the confidence that your valve supply chain is rock solid regardless the pressure it’s under.

Emergency situations are not the only times relief valves are active; once installed they continuously regulate the flow of substance. They can also be pre-set to open when the pressure or temperature gets to a certain point that may be dangerous. Generally valves are placed on or near the pump head of the hose, pipe or tube. A wide variety of relief valve designs exist, although most resemble ball-check valves, swing check valves or diaphragm valves.

This last is particularly useful when controlling a flow of fluids that contains suspended solids. Most relief valves are spring operated, as are the majority of check valves. One specialized type of relief valve is known as a vacuum relief valve. As opposed to a normal relief valve, which relieves high pressure, a vacuum relief valve is used to relieve dangerously low pressures, or vacuums, by inserting air or an inert gas.

Like every other type of check valve, relief valves may be constructed from a variety of materials, including PVC, brass, ductile iron, copper, polyethylene, polypropylene, aluminum, steel, stainless steel and rubber. Which raw substance is used to produce each relief valve depends on the environment said relief valve will be in. The wrong product could result in erosion or contamination of the process stream. However, as long as research is done, finding the appropriate type of relief valve is possible. Every plumbing or fluid transfer application in the industrial, commercial and domestic arenas employ or will employ check valves. In fact, check valves of all kinds are an essential part of every day life. Because they need not be supervised to function and prevent product malfunction, check valves are not only desirable but often required by law to ensure the safety of water, gas and pressure applications.
