kunkle safety valve 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.

They are available in a wide range of materials including Brass, Bronze, Carbon Steel, Stainless Steel, Cast Iron, and Aluminum.

Ask anyone in the industry what brands are synonymous with high-quality safety and relief valves and you are sure to hear the name Kunkle. Kunkle Valve has long been a top manufacturer of safety and relief valves and valve products for a wide variety of commercial and industrial applications, and it all began with the building of the railroad.

Kunkle Valve’s history dates back to about 150 years ago in Fort Wayne, Indiana. It was there that machinist and inventor Erastus B. Kunkle invented the first lock-up pop safety valve. He was working on locomotives for the Pennsylvania Railroad, and at that time, overpressure in the engines could cause serious problems. Kunkle’s invention of the safety valve to release engine pressure revolutionized the industry. In 1875, Kunkle patented the invention, and the following year he and his brother-in-law entered the valve manufacturing business.

The Fort Wayne Safety Valve Works operated as such until four years after Kunkle’s death. In 1917, local Fort Wayne businessman Oscar A. Fox purchased the firm and renamed it Kunkle Valve Company.

In the decades following World War II, Kunkle Valve made an even bigger name for itself providing relief valves for navy ships, nuclear submarines, and other large nautical vessels. In 1991, Kunkle Valve became a part of Anderson, Greenwood & Company, which was later acquired by Tyco Flow Control. In 2012, Tyco Flow Control merged with Pentair Inc. to form Pentair Ltd., which today provides industrial valves, pumps, and other water and fluid solutions on a global scale.

Kunkle Valve continues to be a leading brand in the manufacture of safety and relief valves and valve products. Kunkle products are available for ASME Sections I, IV, and VIII services, and most Kunkle valves have their relief capacity certified by the National Board of Boiler and Pressure Vessel Inspectors. Kunkle safety and pressure relief valves are set and tested in accordance with the API 527 standard for seat tightness of pressure relief valves as well as Kunkle Factory seat tightness standards for air/gas, steam, and liquid service. The company also offers non-code products, which are set and tested to the customer’s specifications. Refer to the Kunkle Safety and Relief Products Technical Reference for more information.
