A valve assembly is provided, the valve assembly comprising a body that defines a fluid flow path between an inlet and an outlet with a frangible member between the inlet and the outlet across the fluid flow path so as to block fluid flow The valve assembly also includes means for rupturing the frangible member, means for biasing the rupturing means into contact with the frangible member and means for retaining the rupturing means away from the frangible member. A magnet is spaced apart from the retaining means a non-magnetic sleeve is disposed between the magnet and the retaining means. The non-magnetic sleeve block a magnetic field provided by the magnet. Also included are means for removing the non-magnetic sleeve, wherein, when the non-magnetic sleeve is removed, in use, the magnetic field attracts the retaining means to release the rupturing means to cause rupture of the frangible member.

A conduit locking device includes a housing having a first end, a second end, and a sidewall disposed between the first end and the second end. The conduit locking device may further include a slide engaged with the sidewall of the housing, the slide including an extension arm and an end portion structurally configured to engage with an inner wall of a conduit. The slide may be extendable via the extension arm from a first position substantially adjacent to the sidewall of the housing to a second position disposed away from the sidewall of the housing, where, when in the second position, the slide is configured to retain the conduit locking device at a fixed position within the conduit through the engagement of the end portion with the inner wall of the conduit.

A packer ring and activation system for use in a pipeline pressure isolation system utilizing a packer, a packer support ring, a primary wedge, and a plurality of secondary wedges for use with a pipe engagement, sealing and testing system.

The device (1) allows the locking of a plug (2) to a fitting (3) and comprises: two locking blades (10), having the outer edge (10B) in an arc of circumference, arranged symmetrically opposite and coplanar to a annular groove (31) of the plug (2), sliding parallel to the latter; actuation means (4) defined by a toothed pinion (13) with which two racks (120) provided in the locking blades (10) are engaged, determining for the same corresponding and synchronized translations in opposite directions, so that the arched edges (10B) are displaced outwards to engage said annular groove (31), locking the plug (2) to the fitting (3). The toothed pinion (13) has a hexagonal head (130) at the top which is engaged by an operating member (15).

A gripper assembly for a pipeline plug includes an actuator plate that includes at least two actuator wedges, a bowl that includes at least two bowl wedges, circumferential wedge sets, and gripper units. Each circumferential wedge set and gripper unit is positioned between the actuator plate and the bowl. Each circumferential wedge set includes a first circumferential wedge and a second circumferential wedge. Each circumferential wedge set is positioned such that an actuator wedge and a bowl wedge engage between the first and second circumferential wedges. Each gripper unit includes a gripper body positioned between and abutting a first circumferential wedge of a first circumferential wedge set and a second circumferential wedge of a second circumferential wedge set. Linear compression between the actuator plate and bowl causes circumferential movement of the circumferential wedges, which in turn causes radial expansion of the gripper units.

A mechanical plug includes first and second plug portions and an elongate member. The first plug portion includes a first endwall and a first sidewall. The first sidewall includes a female section extending in a direction along a longitudinal axis of the mechanical plug. The second plug portion is movable relative to the first plug portion. The second plug portion includes a second sidewall, a second endwall coupled to the second sidewall, and a seal. The second sidewall includes a male section extending in a direction along the longitudinal axis. The seal surrounds a portion of the male section in a region along the longitudinal axis between the second endwall and the female section. The elongate member is coupled to the first and second plug portions. Actuation of the elongate member moves the first plug portion and the second plug portion toward each other to compress the seal.

A cup-shaped cover of a pedal travel simulator, hydraulic accumulator, or a damper chamber, using a radially resilient connecting ring, which protrudes into a groove of the cover and into an opposing groove of a receptacle of a hydraulic block of a traction slip controller of a hydraulic vehicle braking system, to fasten inseparably at the hydraulic block.
