优化的密封设计赋予了其极佳的耐用性与回弹性

热水型

热水型专为温度控制技术应用而开发，适用于高达 200°C 的加压水工况。这对阀座而言属于极严苛的运行条件，因为水垢沉积会导致磨损加剧。其独特的密封设计确保了即使在如此苛刻的条件下，阀门仍能保持极长的使用寿命。在测试中，该阀门在 200°C 和 16 bar(g) 压力下，实现了超过一百万次的开关操作。

高温型

高温型在蒸汽测试中同样表现出色，在高达 230°C 的温度下，经受住了超过一百万次开关操作的考验。

Extremely durable and resilient thanks to optimised seal design

Hot water version

The hot water version was specially developed for temperature control technology. Pressurised water of up to 200°C is used there. This means the toughest operating conditions for the seat valves, since limescale deposits lead to increased wear. The special sealing concept ensures a particularly long service life even under these demanding conditions. In our tests, the valves were able to achieve over one million valve operations at 200°C and a pressure of 16 bar(g).

High-temperature version

The high-temperature version was also convincing in the test with steam, at a temperature of up to 230 °C, with more than one million valve switching operations.

低维护需求

相比价格更低廉的旋转阀，阀座式阀门（Seat valves）因其超长的使用寿命而更受青睐。

得益于全新的压力和温度适用范围，这些阀座式阀门现已成为严苛工况下的理想选择——而在过去，此类工况通常主要使用球阀或蝶阀。

优势在于：设备或密封件极少需要更换，这不仅降低了维护工作量，还降低了总拥有成本。

Low maintenance

Seat valves are preferred over cheaper rotary valves due to their long service life.

Thanks to the new pressure and temperature ranges, the seat valves are now the ideal companion for demanding applications in which ball valves or butterfly valves have mainly been used up to now.

The advantage: The devices or seals need to be replaced only rarely, which not only reduces the maintenance effort, but also the total cost of ownership.
