| •Built-in stainless steel check valve (CV) •Borne pass needle (BVSW) | • Design pressure (PMA): 100bar • Maximum operating pressure (PMO): 45bar • Maximum operating temperature (TMO): 450°C | • Design pressure (PMA): 100bar • Maximum operating pressure (PMO): 45bar • Maximum operating temperature (TMO): 343°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 oversize the orifice; limiting the orifice size is desirable. Specific grinding of the disc and seat, as well as extended inlet pipe and check valves. Provide a set with sufficient diameter and length. Provide sufficient length of inlet pipe so that the trap is lower than the main line. Do not insulate the trap or inlet pipe. |
