| 488 Series Safety Valves | ||
|---|---|---|
|
Staitech offer a wide range of safety valves for steam, liquid and gas applications. In order to select an appropriate valve Staitech will require details of the flow medium, flow capacity and set pressure. All valves are PED compliant and tested in accordance with TUV requirements. The 481, 483, 488 and 646 series valves also meet ASME Section VIII criteria. The 488 series valves are intended for liquid and gas applications up to 16 barg. When fitted with an Perlast seat seal valves are also suitable for steam duty. All valves are fitted with an EPDM bellows which prevents media from entering the spring chamber during discharge. Three orifice sizes and three connection options are available for the 488 valve based on capacity requirements. Standard valves have a sealed gas tight cap with manual rotalift and pneumatic lifting devices also available. Available Options:
