• Safety Valve Test Bench is a very easy, safe,
    accurate and maintenance free operating work
    shop test unit for Testing & Calibration of
    pressure/safety relief valve (spring operated) in
    the range of 0.5’’ to 8’’ (DN – 15 to 200 mm)
    according to the common international test
  • Safety Valve Test Bench is designed to provide
    the operator with a maximum of easiness to
    calibrate the valves accurately.
  • As standard manufacture, the four way manual sliding clamps allow an appreciable gain of time but, on option, pneumatic or hydraulic Machined body/nozzle casting can be fitted on bench.
  • Unique – 4 claw clamping system, specially designed for quickly clamping all common types and sizes of safety valve up to 8’’. The specific configuration of the piping, fitting, and control ensure an
    strong and dynamic lift reaction and accurate test result, high quality, stainless steel gauges
    measure and display in pressure in kg/cm2 (g).
