Valve test benches
Test benches for valves and more
EFCO is a manufacturer of valve test benches for liquid or gaseous test media.
Valves are used in technology and industry as switching, shut-off and safety elements in pipeline construction. Valves are used to direct liquid and gas flows in desired directions, to shut them off completely or temporarily if necessary, or to open them if operating pressures are too high.
Since valves are often subjected to very high loads in practice, they not only have to function perfectly, but are also subjected to high load tests before they are even used in practice.
Valve test benches provide indispensable testing services in engineering to carry out these load tests.
- Valve test benches are used wherever shut-off and control valves, butterfly valves, gate valves, safety valves, globe, angle, two-way and three-way valves are to be tested.
- Valve test rigs thus fulfil important functions by checking and ensuring the operational safety and perfect functioning of the valve types mentioned.
- The valves to be tested are firmly clamped in valve test stands. The test of the respective valve is carried out by pressurizing the test specimen with an internal pressure prescribed for the test. Liquid or gaseous test media are used.
Key features
- Gas, water testing
- Usually hydraulic tension
- High test pressures
- Closed water circuits (fresh water supply)
- Usually up to 385 bar (5580 psi) water and 300 bar (4350 psi) air
- Safety clamp with hydraulic clamping unit
- External test possibility
- Test documentation with EFCO Valve-DOC
- Easy operation
- Long service life
Horizontal test benches
Valve test benches for the clamping of 2-way through valves. The valves are clamped horizontally between 2 test tables.
This means e.g. for DIN flanged valves:
- Inlet/outlet flange = left/right
- Spindle/hand wheel drive = up/front
Advantages
- Underwater testing possible
- Suitable for large test specimens (easy loading and unloading)
Vertical test benches
Valve test benches for the clamping of 2-way straight through valves or safety valves.
This means e.g. for flanged valves:
- inlet flange = bottom
- spindle/hand wheel drive = forward
Advantages
- Especially suitable for safety valves
- Suitable for small test pieces
- Good venting
Test benches for manufacturers and customised test benches
Test benches for pressure testing of test pieces/fittings/housings with special requirements:
- Test sample size,
- Test piece shape,
- Test pressure,
as well as special requirements for the testing process (e.g. automatic operation).
Accessories for test benches
All EFCO test benches are equipped with standard accessories and their functions can be extended with optional accessories.
The accessories include
- O-ring sealing plates
- Polyurethane sealing sheets (Vulkollan)
- Safety plugs (especially for safety valves)
- Threaded adapter (for testing test pieces with threaded end)
