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.

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 things that can affect your customers’ operations, safety and relief valves – installing, replacing, maintaining or servicing them – shouldn’t ever be one of them. That’s why everything North American Safety Valve does in done right and done quickly.

We work exclusively with wholesalers in the safety valve industry, so you never have to worry about us trying to conduct business with your end users. In other words, we’re your support, not your competitor.

We make every effort to ship your order out the same day we receive it. But as you know, a safety valve doesn’t ship as easily as your typical retail product. It takes time to assemble safety valves and test them. If possible, order early enough that we have time to get your safety valve or part carefully prepped for same-day shipping.

In business since 1975 and a team of factory-trained technicians, we feel confident calling ourselves safety valve experts. Our employees are long-timers, and what they know comes in handy when you or your end user has questions about or problems with safety valves. You could try calling the manufacturer with your questions, but that can become frustrating in a hurry. Instead, give us a call and put our collective knowledge to work.

Since the early 1940s, the Farris Engineering unit of Curtiss-Wright Flow Control has designed and produced a wide range of spring-loaded and pilot-operated pressure relief valves. Used as safety devices, Farris pressure relief safety valves prevent over pressurization of vessels, pipelines, and equipment. Farris manufacturing is a company recognized as a leader in the hydrocarbon processing, refinery, petrochemical, natural gas production/transmission, pharmaceutical, and general processing industries worldwide. Their safety valves and other PRV hardware can be found across the globe – from the U.S. to the U.K. and S. America to China.

A pioneer in the field, the Farris Engineering company created many safety pressure relief products that remain industry standards. Integrating its core hardware technology with the information age, Farris developed computer software to assist customers in the sizing and selection of safety valves for all manner of piping and equipment. A recent reorganization of manufacturing plants and processes maximized production effectiveness to position the business unit at the forefront of the industry, with service and delivery second to none. If you are looking for an effective, high-quality safety valve and engineering expertise for any and all pressure relief management questions – look to the safety valve companies Farris Engineering and North American Machine Works.

Valves for industrial applicationsIn order to prevent the uncontrolled rise in pressure in pressure vessels or pressurized pipelines, a safety valve is inserted. The safety valve is designed so that it opens at a given maximum pressure, thereby relieving the line or the container. Safety valves find their use in almost all areas of the pressure vessel and pipeline construction. In cryogenics as a spring-loaded safety valve for example.

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.

A safety valve protects the system and equipment from overpressure. Overpressure develops when the pressure exceeds the system’s maximum allowable working pressure (MWAP) or the pressure under which it has been designed. Safety valves have a short opening time to discharge gases or liquids immediately. A safety valve opens when a certain pressure is reached; it opens partially at first to eliminate undesirable pressure from the system as rapidly as possible.

Safety valves are utilized to stop pressure rises that might cause malfunctions, fire risks, or explosions. Safety valves are utilized when electrical or pneumatic safety systems malfunction since they only have mechanical components. The system’s media fully activates a safety valve, keeping it operational in the case of a power failure.
