Test Bench: High-performance for large valves

The test bench ensures the quality of SAMSON LEUSCH’s control and butterfly valves. The valves are tested for their pressure resistance. At the heart of the testing process is the triple eccentric butterfly valve LTR 43. Pressure is generated in the test bench equal to the pressure in the intended application. If the pressure-bearing components of the valve withstand the test pressure, customers can rest assured that the valve will function stably and durably under operating conditions.

The following pressure tests are performed following the specified standards: Strength test: The test serves to prove the compressive strength of the pressure-bearing components against the internal pressure. The test medium is a water-oil mixture that is stored in a 3000-litre tank; tightness test against internal pressure: the test serves to prove the tightness of the seals against the internal pressure; and seat tightness: the test serves to prove that the specified leakage rate of the seat is maintained.

The test is performed with liquid (water) or gases (air, nitrogen, or helium). Laser technology is used to measure the leakage in bubbles or drops during the testing process. In this way, even the smallest leaks can be detected.

An important parameter regarding the technical data of the Test Bench is the nominal width. It is up to 84 inches. This means that the valve can have an inner diameter of up to 2.10 metres.

Another relevant parameter is the maximum test pressure. With the SAMSON LEUSCH test bench, it is a maximum of 650 bar (water) or 250 bar (gas).
