PRODUCT DESCRIPTION

HG-Stahl High-Temperature Resistant Valves are manufactured from specially designed robust materials, often incorporating metal alloys or ceramic components. The special materials and sealing systems in the valve provide resistance to high-temperature conditions, enabling safe and efficient operation.

The range of HG-Stahl High-Temperature Valves includes ball valves, butterfly valves, globe valves, gate valves, check valves, and bypass valves. The use of graphite technology tailored for high temperatures in these valves is crucial, and we prefer German and Italian-origin brands for these applications.

The internal components of high-temperature valves must not melt at elevated temperatures. In this context, sealing is achieved through metal-to-metal contact. To ensure the longevity of the two metallic sealing elements under prolonged high-temperature exposure, HG-Stahl applies various coating types to the internal components based on fluid type, pressure, and temperature conditions. Our most prominent coating types include Stellite, Chromium Carbide, Tungsten Carbide, Nickel Alloyed Tungsten Carbide, Chromium Oxide, and Titanium Dioxide coatings.

In High-Temperature Valves, materials such as Nickel Alloys (Inconel 600, 625; Hastelloy B, B-2, B3, C276, C-22, C-4, G; Incoloy 800, 800H, 825; Monel 400, K500; Nickel 200, 201), Duplex Stainless Alloys (C95800, C95500, C95400, C63200), AISI 304, AISI 316, or Ceramic Coated products are preferred.

HG-Stahl Engineering, through its Tubitak projects, has also addressed one of the most challenging aspects of valves operating at high temperatures: achieving optimal rotational torque. Using numerous mathematical models, we have developed solutions to achieve zero leakage and low rotational force. Our R&D efforts continue to focus on valves capable of operating beyond current limits.
