Abstract
A method for installing a valve for use in oil and gas production or similar applications includes inserting seats and biasing members into a cavity of the valve and causing the seats to moving axially apart from each other, such that the biasing members are compressed and the flow barrier of the valve may be installed between the seats.
Claims7
A method of assembling a valve comprising:
- inserting into a cavity of a valve body two seats and two biasing members disposed between the valve body and the seats, such that the seats are separated by a first axial distance;
- inserting into the cavity of the valve body a flow barrier with a first width greater than the first axial distance;
- moving the seats axially apart from each other, such that the biasing members are compressed and the seats are separated by a second axial distance which is greater than or substantially equal to the width of the flow barrier;
- and
- moving the flow barrier to a position between the seats, such that the biasing members exert an axial force causing the seats to engage the flow barrier.
