High pressure cylinder valve specific applications - D488
- Non-rotating, thread less lower spindle.
- No particle shedding in gas wetted valve cavity.
- ring and fitted into gland nut guarantee a secondary sealing and exclude humidity
- Soft seat captivated to avoid extrusion and good sealing performances.
- Lower spindle design allows a smooth opening of the valve, and prevents adiabatic compression.
- Possibility to add a Residual Pressure Valve (RPV)
