Advantages • Stem prevented from being ejected in the event of overpressure • Two stem seal to prevent leakage • Corrosion resistance, increased chemical compatibility thanks to chemical nickel plating • Can be operated at very low temperatures: -50°C • Compatible Fluids: Compressed air, water, gas • Working Pressure: 1/4" to 2": 0 to 40 bar • Working Temperature: -50°C to +170°C Reliable performance is dependent upon the type of fluid conveyed. Products have been tested at -50°C in static sealing and after 5 operations for a leak rate < 0,05Nl/h.
