Valve Test Benches
Save Money, Increase Efficiency and Reduce Plant downtime with our range of valve test benches which are suitable for all valve testing requirements and budgets. We offer solutions for testing with liquid or gas and our 3 ranges of test benches all allow for testing at pressures of up to 14,500 psi. A wide range of optional extras are also available, giving the opportunity to select a bespoke solution from a standard range.
Manual Valve Test Benches can be used to test valves up to 12 inches in the enclosure and any size externally. Ideal for low volume pressure testing with both water and gas at pressures up to 14,500 psi (1,000 Bar). 2 test benches configurations are available: Relief Valve Test Bench and Universal Valve Test Bench.
ECO Valve Test Benches incorporate an innovative design which replaces tightening bolts manually, with an O-ring design to seal the valve on test using a hand pump. The design allows for a quicker test set up to the manual range so is ideal for higher volumes. Test pressures of up to 10,000 psi can be reached using liquid as the test medium. The range includes 3 models which allow for relief/safety and shut off valves to be tested.
The Hydraulic Clamping Relief Valve Test Benches are an industry recognised design. The integrated PLC informs the operator of the clamp force and test pressure required for any given size or class of valve. Until the correct clamp pressure is reached test pressure cannot be generated providing an excellent safety feature. Benches can be supplied at test pressures of up to 14,500 psi (1,000 Bar) using Gas, fluid or combined test mediums as standard.

Cycle Test Rigs
The Cycle Range test rigs are ideal for carrying out the repetitive pressure testing of equipment. Whether it be to test equipment to destruction or prove it lasts for a set amount of cycles, the inbuilt PLC can be set to automatically run a test. Variable settings include maximum and minimum pressure of a cycle, time pressure is held every cycle, % of set pressure which dictates pass/fail and number of cycles per test. At the end of each test the touch screen HMI will indicate Pass or Fail and all information can be extracted using a USB. The cycle test rig range also has a safety door locking system as standard, so whenever there is pressure in the system the door will automatically lock until the pressure is released.
Furthermore, the Cycle range has all the features of the ECO and Maxi Ranges and can carry out manual hydrostatic proof, burst and cycle testing up to 55,500 psi (3,828 Bar). The cycle range software and equipment can be added as an extra to both the ECO and MAXI ranges but is also available in a standard vertical configuration to allow for cycle testing of equipment such as cylinders and manifolds as well as hoses.
