There is provided a valve assembly, the valve assembly including a body (8) in which there is housed at least one valve ball (22, 24), a movement assembly (32, 34) for moving the ball between closed and open positions with respect to a channel which passes through the body. At respective ends of the valve body there is provided sealing means (38) including a valve seat, biasing means to bias the valve seat towards contact with the ball, and at least one annular member engaged with the valve body to retain the valve seat, biasing means and at least one ball in the valve body and form a modular unit. Positioned in the valve body outwardly of each of the sealing means, there is provided a fitting means (50) engaged with the valve body and the form of the fitting means is selected and fitted to the modular unit independently of the said at least one annular member.

A rotary valve includes a first ball valve including a first stem extending from a first proximal stem end to a first distal stem end outward from the first ball valve. The first stem including a first slotted opening extending from the first distal stem end into the first stem. The rotary valve includes a second ball valve including a second stem extending from a second proximal stem end to a second distal stem end outward from the second ball valve. The second stem including a second slotted opening extending from the second distal stem end into the second stem, wherein the second stem extends towards the first stem. The rotary valve includes a drive key located within the first slotted opening and the second slotted opening. The drive key extending from the first slotted opening of the first ball valve to the second slotted opening of the second ball valve to operably connect the first ball valve to the second ball valve. The drive key has a non-uniform thickness.

A first flow channel of a flow channel switching valve includes a first portion that is connected to a valve body and that is linear, a second portion that is connected such that the second portion is perpendicular to the first portion and that is linear, and a lid member that is joined such that the lid member covers an opening of a tip end of the first portion. The first flow channel also includes a pair of projecting portions that is disposed such that the projecting portions interpose the first portion therebetween in a radial direction and face each other, and a connecting portion that couples the pair of projecting portions with each other. The pair of projecting portions includes a planar surface portion that faces the valve body direction.

A motorized ball valve has valve body with an actuator bracket receiver. The actuator bracket receiver has a pair of rails. The ball valve also includes a valve stem extending through the actuator bracket receiver and an actuator operably connected to the valve stem. A mounting bracket is connected between the actuator and the valve body to support the actuator. The mounting bracket is captured between the pair of rails of the actuator bracket receiver to offset torsional forces generated by the actuator.

A compact manifold ball valve having a valve body, valve ball, valve stem and two piece retainer system; the valve body including a valve chamber having first and second ends, and a first flow passage intersecting the valve chamber and valve ball. The valve ball can be trunnion supported and include pair of movable seat assemblies that can be used to seal the valve ball to the valve body. A two piece retainer can be used to hold in place the valve components, the two piece retainer including a first section which moves only linearly along with a second retainer piece that is a threaded ring that rotationally locks in place the first section of the two piece retainer. The two pieces of the retainer can be symmetrically located about the centerline of the flow passage of the valve body.

There is provided a valve assembly, the valve assembly including a body (8) in which there is housed at least one valve ball (22, 24), a movement assembly (32, 34) for moving the ball between closed and open positions with respect to a channel which passes through the body.
