AT 810
Description
The basic model within the range of small safety valves for compressed air. It is compact and due to its good blow-off capacities is particularly suitable for the protection of pressure vessels and compressors. However, even for large pressure vessels this valve can be employed due to its excellent price / performance ratio. This valve is equipped as standard with a stainless steel spring and FPM seal.

OK 618
Description
With proportional opening characteristics and even larger setting ranges of the springs, this valve is ideally suited in cases where a stock value for various applications and set pressures is required and the valve needs to be readily available. It is designed in particular for plants in which only low amounts of expansion medium have to be discharged.
Nominal Width: DN10-DN50
Medium: Liquids, Air, gases, vapours and steam
Temperature: -60°C … 225°C
Pressure: 0,2 bar … 20 barUsage Area

TK 851
Description
These high-performance safety valves with bellows are suitable for safeguarding non-intrinsically safe solar systems with temperatures up to over 200 °C as well as district heating supply systems, steam boilers and pressure vessels. The metal bellows protects sliding and moving parts from the medium and thus from dangerous deposits. The spring chamber and pressure spring are protected against steam penetration and high temperatures.
Nominal Width: DN15-DN50
Medium: Liquids, Air, gases, vapours, steam, solar heating systems

TK 852
Description
This safety valve range is also completely made of corrosion-resistant materials. The body is made of gunmetal and the stainless steel spring and internal parts, which are made of stainless steel, are hard to beat in terms of corrosion-resistance, especially when confronted with agressive watery solutions, salt water or a saline atmosphere. The best possible version is available for virtually every application imaginable, whether this requires metal to metal sealing to meet highest tightness requirements or a metal supported o-ring seal made of a variety of materials or even back-pressure compensating gastight metal bellows or a gastight spring housing.
Nominal Width: DN40-DN50
Medium: Liquids, Air, gases, vapour, steam
