Setting of pressure valve: …

The improvement enables an operator to be apprised of the actual opening pressure setting of the valve.

The telemetry signal is processed to produce observer intelligible data indicating the opening pressure setting of the valve.

It’s a shame, we would have liked a lower setting to offer a better level of comfort.

A sensor is implantable at the patient and responds to the actual opening pressure setting, by generating an NIR telemetry signal indicative of the actual setting.

the layout of this calibration curve and the detection of its evolutions,

For stainless steel calibration weights, a density of 8000 kg/m3 shall be used.

The rating means (8) consists of a perforated screw (9) screwed into the body.

A calibrating spring (13) enables to transmit to the mobile plate the pressure load exerted on the intermediate platen.

A flow capacity test on a pressure relief valve is to be conducted at a flow rating pressure of 120 per cent of the maximum set pressure.

The information produced enabled the flow chronology during these brief events to be identified, the flows to be quantified and a rating curve to be established.

Maximum system operating pressure should not exceed 90% of relief valve set pressure.
