The METRUS test bench CSV 10/150 UW is designed for underwater testing (pressure and leak testing) of control and shut-off valves with straight passage and nominal sizes ranging from DN 15 (½") to DN 150 (6"). Tests for shell tightness and seat tightness can be conducted. The sealing of the valves under test is achieved using O-rings in the automatic sealing heads.

The control stand is mounted at a 90° angle to the immersion basin on a common base frame. Operation of all functions is carried out via the control stand, which is clearly labeled and positioned on the front panel. The clamping of the valve under test is motorized and performed in a column frame with an adjustable threaded spindle. The immersion of the clamping unit into the basin is controlled electrically via a two-hand operation for safety.

The required test pressure is available at the pressure inlet valve and can be read on the high-pressure (HP-air) or low-pressure (LP-air) gauges located on the front panel, or on the corresponding test gauge mounted on top of the control stand. The test gauges can be connected tool-free and without significant effort using METRUS quick-connect fittings.

The test bench is equipped with two bubble counters on the control panel for seat leakage testing, enabling precise observation during the testing process.

The METRUS CSV 100/400 Test Bench has been specifically designed for the testing of 2-way control valves with nominal widths ranging from DN 15 (1/2") to DN 400 (16"). Seat tests and casing tests can be performed using various test media.

The clamping unit of the CSV 100/400 can withstand loads of up to 1000 kN (≈ 100 t). The test pressure is set using the specially developed METRUS Precision Needle Valve V30.2 on the corresponding 2-way valve head.

All functions are controlled from the central console. The required test pressure is applied to the pressure inlet valves and can be read either from the test gauges on the control stand or directly on the PC via sensors.

The METRUS CSV 280/600 test stand was specially developed for testing 3-way control valves (mixing valves and distributors) with nominal diameters ranging from DN 100 (4") to DN 600 (24"). Valves in straight-through form can also be tested. Seat and body tests can be carried out with various media.

The clamping unit of the CSV 280/600 has a load capacity of up to 2800 kN (≈ 280 t). The test pressure is set, among other things, via the specially developed precision needle valves on the 3-way valve head.

All functions are operated from the control panel. The required test pressure is available at the pressure inlet valves and can be read off the test pressure gauge on the control stand.
