A valve assembly including a valve having an opening and closing mechanism for controlling the flow of a fluid through the valve controlled by an actuator and an actuator mounting bracket secured to the valve. The actuator mounting bracket includes upper and lower clamps securing the valve actuator to the valve regardless of the valve position.

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 enageable with the second end of the stem driver when the actuator is connected to the upper portion of the mounting bracket.

A ball valve includes a body and a ball subassembly. The body includes a first bore extending partially through the body from a first flange of the body along a first axis, the flange defining an opening, a second bore extending in along a second axis from the first bore to a second flange, wherein the second axis is transverse to the first axis, and a third bore extending along the second axis, opposite the second bore, from the first bore to a third flange. The ball subassembly is configured to be inserted into first bore of the body through the opening. The ball subassembly includes a ball having a ball bore extending through the ball. The ball is configured to rotate about the first axis to open and close the ball valve such that the ball bore is substantially aligned with the second axis when the ball valve is open, and wherein the ball bore is substantially transverse to the second axis when the valve is closed.

A top entry trunnion mounted rotary ball valve suitable for safe in-line maintenance, comprising a main valve body having an upstream and a downstream ball seat assembly, the ball seat assemblies further comprising 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 the 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 the measure of retraction required so as to get the mechanical clearance adequate to remove or assemble the ball member, the angular span between the first end and the second end of the guiding groove can be less than 180 degrees or more than 360 degrees, depending on the overall size of rotary ball valve, in order to be able to manually retract in the ball seats. Each ball seat is retracted in the recess, with the aid of a guide assembly, by using a straight rod, 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 or all components from or inside the valve body. An angle of grove a, which is an angle between the flange and the guide groove, is kept of relatively of low value for big sized valves whence an angular span of guiding groove becomes relatively higher so that the required axial distance, which is equal to or more than the measure of retraction required so as to get the mechanical clearance adequate to remove the ball member, is attainable between the first end of the groove and the second end of the groove, by a Force Ft apply-able by a person of normal physique, and vice versa for a small sized valve. The rotary ball valve cannot be put in operation inadvertently if the ball seats are in retractable or retracted position.

A valve and method for producing a valve for regulating a fluid, the valve including a valve housing with a central part and two connection ends, the connection ends extending away from the central part. Internally of the central part, there is arranged a valve body with a through-going aperture that is arranged in a valve seat and connected to a valve spindle, the valve spindle being arranged in a spindle guide stub on the valve housing. The valve housing is made from a plastically deformed tubular item and includes a collared spindle guide stub with at least one projection, the projection or projections extending in continuation of the spindle guide stub. This projection can be used as a lock ensuring that the valve spindle is retained in its intended position, and at the same time, such projections can form stops at the extreme positions of the valve body.

A modular stop is provided for ball valves, such as those used as drill stem safety valves. The modular stop can be a replaceable component in valves for use with stems used to rotate a ball valve in the valve's body. The modular stop can bear the wear associated with the operation of ball valves and when the modular stop has exceeded its usable service life, it can be replaced without replacing the whole of the valve body. The modular stop can be used in new valve manufacture as well as in the retrofitting or remanufacturing of existing valves.

A seal carrier for a ball valve includes a carrier body to be located between a ball and a portion of a valve body. The carrier body may have an annular channel for carrying a ring seal in a side to be located proximate the ball. A spring is located at a peripheral portion of the carrier body. An end portion of the spring is configured to abut against the portion of the valve body, and the spring is configured to provide a compressive force between the portion of the valve body and the ball in a direction parallel with the direction of fluid flow through the ball valve assembly. A ball valve assembly may include such seal carriers. Methods of forming such seal carriers are also included.

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.

Disclosed embodiments include ball valves with an asymmetric seal and seat, to minimize seal wear. In embodiments, a seal is disposed upon a ball with a first and second section, where the first section of the seal is disposed at a different angle from the second section. A seat has a first and second section at different angles that correspond to angles of the first and second section of the seal, respectively, such that the seal fully contacts the seat when the ball is in a closed position. When the ball is rotated to an open position, the different angles of the first and second sections allow the second section of the seal to clear the first section of the seat without contact.

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.
