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.

NASVI’s 35,000 safety valves in stock in our 100,000 sq. ft. facility means nothing without the people who know every detail about every valve, manufacturer and operations. Combined, our people have well over a century of industry knowledge. And, it’s just a call or email away.

Our specialized computer gives us quick access to availability on any valve. We can provide an accurate price quote, offer alternatives and give a delivery date immediately. No waiting or call backs. Many times this makes all the difference in getting an order. Al Tanis One of our customers recently inquired about the availability of five 4-inch liquid flanged valves.

Paul Stratman "We provide the best service in the business. And that takes the commitment of everyone who works here. We re all in this together working and doing whatever needs to be done to ensure the customer s needs are taken care of. We treat every customer the same and make them our number one priority.

Then, if requested, we can a quotation with a job or reference number to the wholesaler for his records. When the order goes through, he has the information. A quick call to us and the valves are on the way. Norman Pursley Wholesalers tell me we have a reputation of being good people to work with. An example is how we ll talk directly with the enduser at the wholesaler s request. When asked, we even use the wholesaler s name. It gets customer problems solved faster and gives the credit to the wholesaler. Jim Cook Today, keeping abreast of Code requirements in the many jurisdictions can be impossible for a wholesaler. That s why we maintain all the latest Code information in our library. Isaac Kostrow To say the least, safety valves are a specialized field. It takes knowledge of the products, manufacturers and end users. When a customer needs a valve which requires modification, specialized connections, coatings or special materials, we offer quick solutions. On items that take months from the factory, we deliver in days. Bruce McDermid Our whole company is truly committed to the customer. It is great to be part of a team that puts the customer first and can come through for them when they really need us. Kevin Walbridge

4 A RELIABLE ALTERNATIVE is the quality in a remanufactured valve. The difference between remanufactured valves and new OEM valves is: Half the price! Twice the warranty! Lower prices, reliable products and quick availability make remanufactured valves a profitable option. In the past few years, many companies have found that it makes sense to rely on remanufactured safety valves. For most industrial uses, remanufactured valves offer excellent availability and are extremely cost effective without compromising quality or safety. Now you can be part of this growing trend. We not only have the facilities but also extensive experience in all areas of valve remanufacturing. Two-year Warranty Guarantees Workmanship During the remanufacturing process, all valves receive the utmost attention to ensure they meet original specifications. Our quality control program allows our personnel to carefully monitor all steps of the remanufacturing process to assure the highest quality.

After servicing, the valves are set and shipped back to the customer for use during their next scheduled maintenance shutdown. As with our new valves, computer-aided ordering and parts inventory ensure a fast, reliable turnaround for remanufactured safety valves. Check with your Application Engineer for details on how remanufactured valves can work for you and your customers. 4

BEFORE AFTER REPAIR CASE STUDY: Quick Turnaround This severe duty safety valve was sent to the service center for repair. Castings were sandblasted, flanges were refaced, worn critical metal surfaces were resurfaced and machined to original tolerances, and all gaskets, bolts and nuts were replaced. The valve was then tested under the same rigorous quality guidelines as a new valve and returned to the customer. The turnaround... only one week. The savings... significant! 6 The service center updates the valve to the latest design standards when necessary. These upgrades use only genuine factory standard parts to assure maximum reliability and long life. All valves serviced in our repair facility carry a one-year standard warranty. The service center holds ASME s V & UV stamps and National Board s NB & VR stamps. Exchange and Rental Programs It is no longer necessary to purchase large stocks of back-up valves or risk excessive downtime costs due to non-availability of needed valves.

Instead, you provide significant savings in logistics costs during their turnaround maintenance outages. This exchange program is individually structured to meet the needs of each customer. If your customer has safety valves in need of repair but doesn t have the numbers that justify an on-site service unit or can t afford a shut down, a valve rental program can offer a solution. Before a maintenance shutdown, the service center ships the safety valves your customer needs in advance. The old valves are then shipped to the service center for repair, testing and reset. After service, your valves are shipped back to you for replacement of the rented valves. A service center Application Engineer will work directly with you to customize a program to meet your customer s plant s needs.
