TSV Service & Sales, a Division of TRIVACO, offers over 55 years of experience in the Industrial, Commercial and Institutional Industry as mechanical specialty sales engineers and application engineering.  As the “Factory Authorized Assembler” of Kunkle Relief Valves for the State of Indiana and western Kentucky. We provide Kunkle Safety Valves to Industrial Distributors and carry a local inventory of Kunkle Safety Valves that we can ship to you or drop ship to your customer.

Everyone is encouraged to call us and schedule a sales call to discuss our FREE survey of safety valves in your plant. This allows us to identify any relief valve installation problems and check to see if the valves are for the application and service. You will receive value from this service by addressing any potential safety issues proactively and not waiting until an unfortunate event occurs to act!

TSV also keeps record of manufacturer’s specifications for Kunkle Valve, Farris, Consolidated, Crosby and more to ensure the accuracy and quality of your valves.

We have certified our shop with The National Board and now hold the following code stamps; VR, UV, V and NB. This enables us to repair Kunkle Valve or ANY other manufacturer’s code stamped safety/relief valve, to new condition, right here in Indianapolis!

Incorrect lapping and or the use of the wrong abrasives and lapping tools are the most common reasons for leaking valves after repair, leading to lengthened servicing turnaround times. For time critical plant shutdowns, it’s very important that seats and seals are repaired correctly first time.

Kemet have produced a lapping kit that can be used on Tyco, Crosby, and Anderson Greenwood pressure relief valves. The kit consists of:15 Lapping / Polishing blocks, double sided with Kemet composite (D through T2 orifice sizes)

Technically precise, practice-oriented, interesting and with modern training methods, LESER offers a wide range of training courses. With application examples, cutaway models and individual parts, the technology of safety valves is explained in a practical way. In the LESER Chatroom the functions of the different safety valves are demonstrated live. You will assemble, disassemble and test safety valves.

Pentair Valves & Controls’ newly introduced Crosby HCI ISOFLEX is a high-capacity safety valve to help power plant operators reduce lifecycle costs and minimize shutdown periods. The valve ensures cost-effective power plant operation with a unique full-nozzle, flanged design and adjustable lift option that reduces maintenance costs while maximizing plant efficiency. Specifically designed for 300 to 3,000 psig steam generators, the HCI ISOFLEX can withstand temperatures up to 1,100F/593C and is available in various inlet sizes, ranging from 1½ inch (38.1 mm) to 6 inches (15.24 cm). An extensive range of interchangeable spare parts enables operators to repair or exchange components individually, avoiding costly replacements and minimizing shutdown time.

The valve is also available with an optional restricted lift feature to eliminate overcapacity and ensure a more economic distribution of relieving capacity between the drum and superheater safety valves. This design not only reduces reaction forces for a greater lifespan but also allows for the use of smaller superheater safety valves in some operations, reducing overall installation costs. Additional benefits include precise blowdown control due to a two-ring design and exceptional seat tightness up to 95% of valve set pressure. (valves.pentair.com/valves)
