| Selection | Restrictions (Alloy) | Installation Instructions |
| •Built-in stainless steel check valve (CV) | • Design pressure (PMA): 160bar • Maximum operating pressure (PMO): 69bar • Maximum operating temperature (TMO): 475°C | Keep the valve body vertical during installation to ensure vertical up and down movement of the bucket. |
| Operation in overheating condition | For superheated steam |
| Under normal working conditions, what generally enters the inverted bucket steam trap is saturated steam and condensate. Superheated steam may also enter, but its condensation rate is basically equal to that of the steam in the valve. Therefore, regardless of the superheat, the steam trap is always at saturated temperature (or slightly lower). | Do not select too large a valve orifice, limit the orifice size, it is advisable to specially grind the disc and seat, and lengthen the inlet pipe and check valve. Provide a header with sufficient diameter and length . Provide a sufficient length of inlet pipe so that the steam trap is lower than the main line. Do not insulate the steam trap or inlet pipe. |
