Technical Features
Test pressure (PT): PS x 1.43 bar.
Body: made in painted carbon steel.
Standard nitrogen valve : ⅝” UNF.
Constructive methodology: two different parts united whit a special threading that under condition of dynamic pressure tends to selfblock.
Working temperature for standard execution: from - 20°C to + 90°C.
Standard diaphragm: can be used with mineral oils and non corrosive fluids.
Installation: in every position.
Compression ratio:
- recommended: P2/P0 = 2.5.
- maximum : P2/P0 = 6.
Mechanical life: the number of cycles is inversely proportional to the increase compression ratio.
Available :
- HST..LT with diaphragm suitable for working temperatures to –40 °C.
- HST .. M: rechargeable with nitrogen valve M28x1.5.
- HST .. V: not rechargeable with a fixed nitrogen preload in the factory.
- HST .. S: separator of fluid.
- hydraulic execution ½ BPS.
According to: 97/23/CE-PED, 94/9/CE-ATEX Group II Cat 2, GOST-R (Russia), SELO (China).
