Abstract: A device for monitoring a seal assembly includes a body having a central axis and a through-passage, a piston slidably disposed in the through-passage and biased towards one end of the body by a biasing member, and a signaling assembly coupled to the body. The signaling assembly includes an indicator and a switch coupled to the indicator. The through-passage and the piston are exposed to a fluid pressure in the seal assembly. The piston is configured to translate axially in the through-passage to transition the switch between a first position and a second position, allowing the switch to transition the indicator between a deactivated state and an activated state.

A hydraulically-actuated wrench has a head with a multi-faceted portion that engages the corresponding multi-faceted segment of the torque transfer tool. The wrench's hydraulic cylinder rotates the wrench head upon actuation. The multifaceted segments can be splined. Also disclosed is a reaction tube against which the wrench can be braced prior to actuation of the cylinder.

Abstract: A gate valve comprises a valve body having an internal working fluid passage with a longitudinal axis and an internal gate chamber extending transverse to the working fluid passage. In addition, the gate valve comprises a gate disposed in the internal gate chamber and movable within the gate chamber between a closed position obstructing fluid flow through the working fluid passage and an open position allowing fluid flow through the working fluid passage. Further, the gate valve comprises an internal sealing arrangement coaxially disposed in the working fluid passage and extending between the valve body and the gate to form a barrier between the internal working fluid passage and internal gate chamber. Still further, the gate valve comprises an internal venting passage extending from the internal gate chamber to the internal working fluid passage for selective venting of fluid pressure from the internal gate chamber to the internal working fluid passage.
