MONOFLANGE VALVE

摘要

A monoflange valve including a valve body having an inlet, an outlet, and an internal bore, and a valve assembly having a valve member disposed in the internal bore for cooperating with a valve seat to open or close a flow path through the valve body. The valve seat may be disposed in the internal bore at a central region of the monoflange body proximal the inlet for enhancing fluid flow through the monoflange body. One or more valve assemblies may be provided, each having a corresponding valve seat that may be located at the central region proximal the inlet passage. One or more projections may extend radially outwardly from the valve body, and the valve assemblies may have a sealing member welded to the corresponding projection at a location spaced radially outwardly from the valve body for facilitating welding and/or inspection of the weldment.

1. A monoflange valve assembly comprising:
a monoflange body having:
an axial inlet fluid passage disposed at a central region of the monoflange body,an outlet fluid passage fluidly connected to the axial inlet fluid passage, andan internal bore extending radially inwardly from a radially outer periphery of the monoflange body to a valve seat; and a valve assembly having a valve member disposed in the internal bore, the valve member having a sealing surface for engaging the valve seat; wherein the valve member is movable in the internal bore between a closed position in which the sealing surface engages the valve seat to close a flow path between the inlet fluid passage and the outlet fluid passage, and an open position in which the sealing surface disengages from the valve seat to open the flow path between the inlet fluid passage and the outlet fluid passage; and wherein the valve seat is disposed at the central region of the monoflange body between the inlet fluid passage and the outlet fluid passage to enhance fluid flow through the monoflange body.
