Flange Pressure Gauges
A flange pressure gauge is fitted into the panel from the front and secured through its front ring. Three figures drive the selection: case diameter, measuring range and connection thread. Choose the range so the normal operating pressure sits around the middle third of the scale, because readings at either end of the scale lose accuracy.
FAQ
Frequently Asked Questions
Which measuring range should I choose?
One where the normal operating pressure sits in the middle third of the scale. With the working point at the bottom the reading is imprecise; at the top there is no reserve for pressure peaks. The range of each article is in its designation and in its technical data.
What sets the precision version apart?
It holds a tighter accuracy class and is used where the reading justifies a setting rather than merely showing presence. The accuracy class is listed in the technical data of every article.
Which connection is common?
The connection closes the type designation, frequently as a G thread. Check thread form and nominal size separately: a parallel G thread does not replace a tapered NPT thread, even where the size figure looks the same.

Hydac Pressure Switches
A pressure switch monitors a pressure and switches once a set value is exceeded or undershot. On the electronic EDS series, pressure range, output type and electrical connection are specified separately. A range chosen too wide costs resolution exactly where the working point sits.
Reducing Fittings
A reducing fitting sits between two threads of different size, one in the component and one on the line. Check thread form and nominal size separately, because parallel G threads and tapered NPT threads are not interchangeable. If one side is wrong, assembly fails or the joint leaks under operating pressure.
Counterbalance Valves
During lowering the counterbalance valve does the braking work, so the lowering speed is set by the control system and not by the load. If that braking action is missing or the valve is wrongly sized, the load sags on start-up and the lowering motion turns jerky.
Bladder Accumulators
A bladder accumulator is a hydropneumatic pressure vessel: inside the steel shell, an elastic bladder separates the nitrogen-precharged gas side from the oil side. When system pressure rises the accumulator takes in oil, and when it falls it gives the oil back. That is how you store energy, damp pulsations, absorb pressure surges or compensate for leakage losses. Four figures narrow the selection: nominal volume, permissible working pressure, port and the elastomer of the bladder, which has to suit the medium and the temperature. Typical nominal volumes range from about 4 to 50 litres with pressure ratings up to 350 bar. PTS supplies bladder accumulators from Parker Olaer, HYDAC and Bosch Rexroth from stock, plus mounting clamps, seal kits and replacement bladders, so an accumulator can be repaired instead of replaced outright.
