Abstract: Apparatus for independently controlling the seating force in a rotary valve are described herein. An example apparatus includes a rotary valve having a flow control member and a dual-acting actuator operatively coupled to the rotary valve. The actuator has first and second ports to receive a pressurized control fluid to change a position of the actuator. The example apparatus further includes a valve controller operatively coupled to the actuator to control the pressurized control fluid in response to a position of the rotary valve. The example apparatus further includes a pressure limiter operatively coupled to the valve controller and fluidly coupled to the first port of the actuator. The pressure limiter is to reduce a pressure of the pressurized fluid provided to the first port of the actuator to reduce a seating force of the flow control member when the rotary valve is in a closed position.

Title: Low profile remote trigger for hydrostatically set borehole tools
Inventor: O'CONNOR KEVEN
IPC: E21B41/00
Filed: 2017-08-09
Abstract: A pin whose movement triggers setting of the borehole tool, is initially held by a collet that is supported off a surrounding housing. A spring is supported off the pin and would push a housing that locks the collet to the pin axially to unsupport the collet but for the presence of a Kevlar® wire that has an associated heater. The wire pulls the housing that locks the collet against the spring bias and has an end attached to the pin. Melting the wire allows the spring to move the housing that traps the collet to the pin. At that point hydrostatic pressure can move the pin to either open a port on the borehole tool to set it hydro statically or to move an actuation rod attached to the pin to set the borehole tool mechanically or with a combination of mechanical and hydraulic force.
