An actuator mounting kit and method for mounting an automatic valve actuator to a manually operated valve. The mounting kit includes a mounting bracket and a stem driver. The mounting bracket is connectable to the valve and has a bottom portion with a stem aperture through which a valve stem is extendable and a tongue matingly engageable with a slot of the valve body. The mounting bracket has an upper portion with a driver aperture aligned with the stem aperture. The stem driver has a first end matingly engageable with the valve stem and a second end extendable through the driver aperture in a way that the actuator is matingly engageable with the second end of the stem driver when the actuator is connected to the upper portion of the mounting bracket.

A valve including a flow control assembly having an adaptive, floating closure member is provided. In one embodiment, a ball valve includes a floating closure member having a shoulder enclosed within a recess of the valve body. The recess is larger than the shoulder of the closure member and allows axial movement of the closure member with respect to the valve body and along a flow path through the valve. Additional valve systems, devices, and methods are also disclosed.

A system includes a ball valve with a housing having a fluid passage, a ball disposed within the housing along the fluid passage, and a stem coupled to the ball. The stem is configured to move the ball between an open position and a closed position relative to the fluid passage. The stem is disposed in a first opening on a first side of the housing. The stem is removable from the first opening, through at least one opening in the ball, and out through a second opening on a second side of the housing.

A ball valve is provided. The ball valve includes at least one load varying mechanism provided in the static body assembly. The load varying mechanism includes a biasing member pressing one of the ball seat seals against the outer surface of the ball of the ball valve with a variable sealing load force applied on the ball, toward the ball and coaxial with the direction of the fluid. The load varying mechanism also includes a movable member operatively connected to a cam and to the biasing member, a rotation of the cam translating the movable member coaxially to the direction of the fluid, in order to variably load the biasing member toward or away from the ball, based on the different positions of the ball.

A top entry ball valve comprises a housing with a central cavity communicating with two bores which define a flow path through the housing. A ball valve element is provided and comprises a through bore. The ball valve element is rotatably mounted within the central cavity for rotation about an axis for selectively aligning the through bore with the housing bores. The ball valve element further comprises first and second flat surfaces on opposite sides of the ball valve element. The flat surfaces are perpendicular to the axis. The top entry ball valve further comprises first and second seats which are configured to provide a seal between the ball valve element and the central cavity. First and second protective rings are provided for receiving and supporting at least a portion of the first and second seats.

A top entry trunnion mounted rotary ball valve defining a main valve body having an upstream and a downstream ball seat assembly, the ball seat assemblies further including a soft insert seal, a ball seat, a seat retainer and a plurality of compression springs in between the ball seat and the seat retainer. A guiding groove on a cylindrical surface of each of the ball seats, having a first end and a second end at an axial distance equal to or more than a measure of retraction required so as to get a mechanical clearance to remove or assemble the ball member. Each ball seat is retracted in a recess against a force Fc of the compression springs and the mechanical clearance is created between the ball member and the soft insert seal, to remove or assemble the ball member and or any component from inside the valve body.

A fluid valve, in particular for a motor vehicle and/or a temperature control system, having a housing and a valve body disposed in the housing so as to be rotatable about a rotation axis. The housing has a first port and a third port disposed on opposite side of a normal plane in relation to the rotation axis and a second port which is radially spaced apart from the rotation axis and in the direction of the rotation axis is disposed between the first and the third port. The valve body in at least one rotary position connects at least two ports of the housing to one another, and in at least one other rotary position does not connect the two ports to one another.
