ABSTRACT:
The valve described herein, includes a hollow valve body having inlet and outlet passageways extending into the body and a valve member positioned in the body for movement between open and closed positions. A plurality of orifice members are disposed between the inlet and the outlet so that fluid flowing through the valve must pass therethrough. The orifice members are arranged so that fluid flow from inlet to the outlet must follow a tortuous path through a series of orifices. The orifices are sized to restrict fluid flow and thus reduce the pressure as the fluid flows through the valve. Also, the relatively long tortuous flow path is provided so that the pressure is reduced over a considerable distance with as little noise as possible. The orifice members are arranged so that the inlet to each series of members is through an annular space that is narrower than the smallest of the orifices so that any particle passing through the annular space will pass through the valve.
