Valve test bench SPTE-1-1
Bench description
The horizontal test bench is combined with a pumping station and integrated
as a one-piece construction – a clamping device for sealing valves
and a pressurizing source.
It has small overall dimensions, which saves space in the test section
and does not require an additional investment in the purchase of a
pneumohydraulic station.
Purpose
■ strength and density tests of body parts materials and welds under
pressure of the test medium
■ gate tightness tests
■ environmental leakage tests on dynamic and static connection seal
■ functional tests
Tested products
■ gate valves
■ ball valves
■ stop valves
■ non-return valves
■ butterfly valves
■ plug valves
Type of connection
■ flanged
■ welded (at the customer’s request)
■ nipple joint
Advantages
■ all components coming into contact with water
are corrosion-resisting or have antirust coating
■ power hydraulic of the clamping device is actuated by the oil
pumping station, which lengthens the test bench lifetime
■ valves testing on gate tightness from both sides does not require
the tested valves adjustment, which significantly cuts the time for
the test preparation
■ the test bench is equipped with a tray for drained water
■ usage of high-pressure hoses with quick-release coupling (QRC)
allows to cut the testing time substantially
■ the test bench may be promptly adjusted to the face-toface
dimension of the valve due to the available electrically or
hydraulically actuated crossbeam
■ the method of the fastening of the tested valves allows to inspect
the leaks
■ by agreement with the customer, it is possible to equip the test
benches with self-sealing stopper plugs ensuring minimal axial
compression of the tested valves
