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.

There are more than 2300 valve manufacturers in the domestic market. There are several categories of valve products, more than 3500 varieties and more than 40000 specifications. Let"s introduce the classification of valves!

Low pressure valves are generally used in urban construction systems. At present, they are developing in the direction of environmental protection and energy saving. Environmentally friendly rubber plate valve, balance valve, midline butterfly valve and metal seal butterfly valve are gradually replacing low-pressure iron gate valve. The valves required for domestic urban buildings are mostly balance valves, soft seal gate valves, butterfly valves, etc.

In the urban heat generation system, a large number of metal hard sealing butterfly valves, horizontal balance valves and directly buried ball valves are required. Because these valves solve the problems of vertical and horizontal hydraulic imbalance of pipelines, so as to achieve the purpose of energy saving and heat generation balance.

In the domestic environmental protection system, the water supply system mainly needs midline butterfly valve, soft seal gate valve, ball valve and exhaust valve (used to remove the air in the pipeline). The sewage treatment system mainly needs soft seal gate valve and butterfly valve.

Urban gas accounts for 22% of the whole natural gas market, with large consumption of valves and many types. It mainly needs ball valve, plug valve, pressure reducing valve and safety valve.

Long distance pipelines are mainly crude oil, finished products and natural pipelines. The valves with most demand for this kind of pipeline are forged steel three body full-diameter ball valve, sulfur resistant flat gate valve, safety valve and check valve.

a. For oil refining units, most of the valves required by oil refining units are pipeline valves, mainly gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves and steam traps. Among them, the demand for gate valves accounts for about 80% of the total number of valves (valves account for 3% ~ 5% of the total investment of the unit).

b. Chemical fiber devices, chemical fiber products mainly include polyester, acrylic and vinylon. The required valves are ball valve and jacketed valve (jacketed ball valve, jacketed gate valve and jacketed stop valve).

c. Acrylonitrile unit. The device generally needs valves produced according to API standard, mainly including gate valve, stop valve, check valve, ball valve, drain valve, needle valve and plug valve. Among them, gate valve accounts for about 75% of the total number of valves.

d. Ammonia plant. Due to the different synthetic ammonia and purification methods, the process flow is different, and the technical performance of the required valves is also different. At present, domestic ammonia plants mainly need gate valve, stop valve, check valve, drain valve, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve and high temperature and low temperature valve. Among them, the stop valve accounts for 53.4% of the total data of valves for the unit, the gate valve accounts for 25.1%, the drain valve accounts for 7.7%, the safety valve accounts for 2.4%, and the regulating valve, low temperature valve and others account for 11.4%

e. Ethylene plant is the leading device of petrochemical industry, which needs a wide variety of valves. Gate valve, globe valve, check valve and lifting rod ball valve account for the majority, of which gate valve shall take the lead“ In the tenth five year plan, 6 sets of ethylene plants with an annual output of 660000 tons need to be built in China, and the demand for valves is considerable. In addition, large ethylene and high-pressure polyethylene units also need ultra-high temperature, lower temperature and ultra-high pressure valve series products.

f. Air separation unit“ "Air separation" means air separation. The device mainly needs stop valve, safety valve, check valve, regulating valve, ball valve, butterfly valve and low-temperature valve.

g. Polypropylene device, polypropylene is a polymer compound polymerized with propylene as raw material. The device mainly needs gate valve, stop valve, check valve, needle valve, ball valve and drain valve.

The construction of power stations in China is developing in the direction of large-scale, so large-diameter and high-pressure safety valves, pressure reducing valves, stop valves, gate valves, butterfly valves, emergency shut-off valves, flow control valves and spherical sealing instrument stop valves are required.
