SV 20/400
The SV 20/400 valve test bench is used for testing safety valves with flanges up to a nominal diameter of DN 400 / 16". It is particularly suitable for adjusting safety valves, as well as for leak and pressure tests on valves after repairs.
The test specimens are only closed at the clamped (lower) flange. The test item is clamped in the clamping unit with 2 clamping claws. The available test media are high-pressure air or N2 up to 300 bar from external sources, e.g. compressors (provided by the customer, not included in the scope of delivery).
The test pressure is controlled via precision needle valves on the respective valve head. The pressure at the valve head is indicated on the upstream pressure gauge on the front panel of the control stand.
The test pressure gauges are connected via two parallel pressure gauge quick connectors (G½”) on the top of the control cabinet. The parallel connections allow the use of a pressure sensor or a comparison manometer in addition to the actual test pressure manometer.
A bubble counter is mounted on the right side of the control cabinet, which can be connected to the outlet of the valve via an air hose and rubber plug.
