A valve lock for a linear valve system includes a housing including a passage configured to receive a rod of a linearly extendable valve member of the linear valve system, and a collet assembly received in the housing, wherein the collet assembly has a central axis extending parallel the rod of the valve member, a radially inner configuration with respect to the central axis of the collet assembly, and a radially outer configuration relative to the central axis of the collet assembly, wherein the lock includes an unlocked configuration associated with the radially outer configuration of the collet assembly, and a locked configuration associated with the radially inner configuration of the collet assembly and which locks against the rod of the valve member and thereby prevent the rod from travelling in at least one axial direction.

A valve assembly including a valve arranged to move between open and closed positions by rotating an operating member about an axis is provided. An actuation unit includes a torsion spring, a trigger member, and a driving member. The driving member engages with the operating member to drive rotation of the same. The torsion spring applies a first torque to the driving member around the axis in a first rotational direction. An external second torque opposite the first torque resets the valve to the open position in which the driving member is held by a latching mechanism. The latching mechanism is arranged to hold the driving member only when the valve is in the open position. An external force applied to the trigger member releases the driving member from the latching mechanism, the first torque thereby rotating the driving member to mechanically bias said valve to the closed position.

A standoff comprising a handle that is adjustably associated with a bracket, with the handle self-latching in relation to bracket at a desired position and at a desired quantifiable torque in relation to the bracket.

Disclosed is a friction ring including a body and a contact member. The body is configured to couple the friction ring to at least one of a faucet assembly or a faucet valve assembly. The contact member is disposed on the body. The contact member is configured to slidably engage with a valve stem of the faucet valve assembly. The contact member is further configured to press against the valve stem to increase a frictional force between the contact member and the valve stem over a full range of movement of the valve stem.

A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

A valve arrangement comprises a rotatable part 32 rotatable relative to a stationary part 12, wherein one of the rotatable part 32 and the stationary part 12 includes an abutment surface 36a, 36b engageable with a stop associated with the other of the rotatable part 32 and the stationary part 12, wherein the stop comprises a stop pin 40 of hollow, substantially cylindrical faint

The invention relates to shut-off valve for controlling flow of a pressurised gas. The shut-off valve comprising a body defining a passage extending between a gas inlet channel and a gas outlet channel, a sealing element, and an emergency stop mechanism. The sealing element arranged to, in a first position, close the passage, and in a second position, open the passage to allow gas to flow between the gas inlet channel and the gas outlet channel through the passage. The invention also relates to a method for controlling flow of a pressurised gas with a shut-off valve and a method for activating an emergency stop of a shut-off valve.
