The gate channel has a central longitudinal axis and a ridge defining a perimeter of the third opening. The valve cover can fit over the third opening and, under force on the valve cover, exert a clamping force on the ridge. The clamping force has a first force component perpendicular to the central longitudinal axis and a second force component parallel with the central longitudinal axis. The first force component of the clamping force is toward the gate channel. The ridge includes a first surface configured to mate with a first surface of the valve cover.

A butterfly valve includes a body, a gear assembly, a shaft, a Scotch yoke actuator on the shaft, and a gear box cover. The body has a fluid conduit and a gear platform supported on and over the fluid conduit. The shaft passes through the gear platform. The gear assembly is supported on the gear platform and includes a valve stem with a first threaded portion and includes a pin nut with a second threaded portion engaging the first threaded portion. The Scotch yoke actuator engages the pin nut. The gear box cover defines an internal cavity sized to house the gear assembly.

Butterfly valve

A control valve body has a flow passage including an inlet, an outlet, a first portion, and a second portion, the first portion having a first axis centered through the inlet, a first bend, and a second axis, the second portion having a third axis centered through the outlet, a second bend, and a fourth axis, the fourth axis perpendicular to the second axis. The first portion is to an upstream side of a junction of the first portion and the second portion, and the second portion is to a downstream side of the junction. The second axis is centered through the junction. An opening to the second portion has a fifth axis aligned with the second axis.

Control valve

A seal includes a first elastomeric ring and a second elastomeric ring. The first elastomeric ring has an annular cavity, and the second elastomeric ring is in the annular cavity. In another embodiment, a seal includes a first elastomeric element and a second elastomeric element. The first elastomeric element has a length extending along an axis, a first surface facing radially outward with respect to the axis, and a second surface facing radially inward with respect to the axis. The second surface defines a cavity extending along the axis. The second elastomeric element is in the cavity and has a first surface facing radially outward with respect to the axis.

Seal with first elastomeric element and second elastomeric element

A cam ring for a pipe connector includes a first axial side, a second axial side opposite the first axial side, a radially outward-facing side, a radially inward-facing side, and a cam element extending a circumferential length along the radially inward facing-side. The cam element includes a first cam section and a second can section, the cam sections respectively have first and second radially facing cam surfaces adjacent respective first and second axially facing cam surfaces. The second radially facing cam surface has a second radial depth lesser than a first radial depth of the first radially facing cam surface. The second axially facing cam surface has a second axial location closer to the first axial side than a first axial location of the first axially facing cam surface. A gripper for a pipe connector includes a body and teeth with an arc shape.

Pipe connector cam ring and gripper

A gripper for a pipe connector includes a body, a first tooth, and a second tooth. The body has a first side, a second side adjacent the first side, a third side adjacent the first side and opposite the second side, and a fourth side adjacent the second side and the third side and opposite the first side. The first tooth extends from the fourth side of the body at a first distance from the first side of the body perpendicular to the first side of the body. The second tooth extends from the fourth side of the body at a second distance from the first side of the body perpendicular to the first side of the body. The second distance is less than the first distance.

Pipe connector, gripper, and gripper teeth

A butterfly valve includes a body and a gear box cover, the body having a fluid conduit and a gear platform supported on and over the fluid conduit, the gear platform configured to support a gear assembly for actuating a valve disk between an open position and a closed position, the gear box cover defining an internal cavity, the internal cavity sized to house the gear assembly, the gear box cover configured to be removably mounted to the platform such that the internal cavity is between the gear box cover and the platform.

In embodiments, a gate valve includes a valve body including a flow passage from a first opening to a second opening, and a gate channel having a first end intersecting the flow passage and a second end delineated by a third opening. A valve cover fits over the third opening. A cap fits over a valve cover opening. In embodiments, a valve cover includes a body with a second sealing surface protruding from a first sealing surface, both around an opening of the body. A cap has a third sealing surface to mate with the first sealing surface, and a fourth sealing surface congruent to the second sealing surface. In embodiments, a valve cover cap includes a body with a first sealing surface on an end of a wall. Pin flanges each have a pin hole having a pin hole axis oriented perpendicular to a center axis of the wall.

In embodiments, a gate valve includes a body including a flow passage from a first opening to a second opening, and a gate channel from the flow passage to a third opening, the gate channel having a central longitudinal axis and a ridge defining a perimeter of the opening. A valve cover can fit over the third opening and exert a clamping force on the ridge, the clamping force having a first force component perpendicular to the central longitudinal axis and a second force component parallel with the central longitudinal axis. In embodiments, a valve cover includes a first mating surface configured to extend over an opening of the gate valve, a first clamping section extending at a first non-parallel angle from a first side of the first mating surface, and a second clamping section extending at a second non-parallel angle from a second side of the first mating surface.

A pipe connector includes a body, a cam ring, a seal element, a push ring, and a gripper. The body has an aperture through an outer surface. The cam ring is configured to be located around the outer surface. The seal element is configured to be seated around an inner surface of the body. The push ring is configured to be slideably located within the body, and to have an aperture configured to be aligned with the aperture of the body. The gripper is configured to be located through the aperture in the body and into a first depth of the cam element. The cam ring is configured to rotate, moving the gripper axially to draw the push ring against the seal element and to move the gripper radially to grip the pipe.
