Abstract
Fluid apparatus and related methods are disclosed. An example fluid apparatus includes a housing defining a fluid flow passageway between an inlet and an outlet. The housing has a first valve seat and a second valve seat positioned in the fluid flow passageway. The first valve seat is spaced from the second valve seat. A flow control member is positioned in the fluid flow passageway. The flow control member has a first disk and a second disk. The first disk is to engage the first valve seat and the second disk to engage the second valve seat.
Claims21
A fluid apparatus comprising:
- a housing defining a fluid flow passageway between an inlet and an outlet, the housing having a first valve seat and a second valve seat positioned in the fluid flow passageway, the first valve seat being spaced from the second valve seat;
- and
- a flow control member positioned in the fluid flow passageway, the flow control member including a first disk and a second disk, the first disk to engage the first valve seat and the second disk to engage the second valve seat.
An apparatus comprising:
- a housing defining a valve seat positioned in a fluid flow passageway between an inlet and an outlet;
- and
- a flow control member positionable in the fluid flow passageway, the flow control member including:
- a body;
- a disk coupled to the body, the disk having a center portion coupled to the body and a peripheral edge extending from the center portion;
- and
- a head portion to couple the flow control member to the housing.
An apparatus comprising:
- a bonnet having a cavity and defining an outlet;
- a valve body to be coupled to the bonnet, the valve body defining an opening including a first valve seat, a second valve seat and an inlet;
- and
- a poppet having a body and a head, the head to be positioned in the cavity of the bonnet and at least a portion of the body to be positioned in the opening of the valve body, the poppet having a first disk and a second disk spaced from the first disk, the first disk having a first aperture to receive the body of the poppet and a first peripheral edge to engage the first valve seat, the second disk having a second aperture to receive the body of the poppet and a second peripheral edge to engage the second valve seat, the head of the poppet being coupled to the bonnet via threads to enable adjustment of a preload of at least the first disk or the second disk.
