Abstract
A fluid regulator includes a balance port regulator valve and an actuator coupled to the regulator valve. The regulator valve has an inlet, an outlet, a valve port disposed between the inlet and the outlet, and a valve disc movable along a longitudinal axis between a closed position in which the valve disc sealingly engages the valve port and an open position in which the valve disc is spaced apart from the valve port. The actuator is responsive to fluid pressure to move an actuator stem along the longitudinal axis. A connector assembly operably and removably connects the valve disc to the actuator stem.
Claims19
A fluid regulator, comprising:
- a balanced port regulator valve having an inlet, an outlet, a valve port disposed between the inlet and the outlet, and a valve disc that is movable along a longitudinal axis between a closed position in which the valve disc sealingly engages the valve port and an open position in which the valve disc is spaced apart from the valve port;
- a valve stem that is coupled to the valve disc;
- an actuator coupled to the regulator valve and responsive to fluid pressure to move an actuator stem along the longitudinal axis;
- and
- a connector assembly that operably and removably connects the valve stem to the actuator stem, wherein a biasing member bears on the connector assembly to bias the valve disc away from the valve port.
A pressure regulator, comprising:
- a valve body having an inlet, and outlet, and a port between the inlet and the outlet;
- a balanced trim assembly having a valve stem, a valve disc that is coupled to a first end of the valve stem, and a connector assembly that is coupled to a second end of the valve stem;
- an actuator stem that is removably coupled to the connector assembly and is configured to be moved in response to fluid pressure at the outlet;
- a biasing member that bears on a surface of the connector assembly to bias the valve disc away from the port.
