The invention relates to a 3-port valve for passing fluids therethrough, having a valve body, a port, a first sub-port and a second sub-port, with the port being adjoined by a main line which ends in a connecting region, said first sub-port having a first sub-port line that is connected to the connecting region, said second sub-port having a second sub-port line that is connected to the connecting region, with at least one valve member being arranged in the connecting region, which valve member can be displaced along a valve member axis between an opening position and a closed position thereof in the connecting region, so that, in a first valve position, the port is fluidically connected to the first sub-port, in a second valve position, the port is fluidically connected to the second sub-port, in a third valve position, the port is fluidically connected to both the first and second sub-ports, in a fourth valve position, the port is fluidically connected neither to the first sub-port nor to the second sub-port. The invention is characterized in that the valve body is formed from a high-tempered steel, or other suitable material, with the valve body being produced from a solid ingot and with the connecting region, the main port, the first sub-port line and the second sub-port line having been machined into the steel ingot. Heat transfer medium lines for passing a HTM therethrough are also machined into the same valve body to regulate the temperature of the fluid. Simultaneously or alternatively, electric heating cartridge receptacles may be machined into the valve body ingot.

A serviceable valve carousel system may include a valve carousel housing having a valve carousel receiver, a valve service port, an integrated first port adapter, and an integrated second port adapter. A rotatable valve carousel may be rotatably disposed within the valve carousel housing. The rotatable valve carousel may include a substantially cylindrical portion, a removable valve lumen, a valve cap receiver, and a removable valve cap having a substantially radiused portion compatible with a substantially radiused portion of the substantially cylindrical portion of the rotatable valve carousel. The rotatable valve carousel is rotatable between a first state that allows fluid communication through a removable valve at least partially disposed within the removable valve lumen and a second state that allows the removable valve cap and removable valve to be removed and replaced via the valve service port without use of tools while maintaining a sewage connection.

A manual operator a hydraulic operator is connected to move a gate within a gate valve body between a valve open and a valve closed position. The manual operator is used to operate the gate valve when the hydraulic operator is not used. On the other hand, a handwheel for the manual operator can be removed when the hydraulic actuator is used to operate the gate valve.

A valve assembly, comprising: a valve housing body extending along a longitudinal axis X between a first end and a second end and defining a cylindrical passage therethough from the first to the second end; a fluid inlet at the first end for receiving a pressurized fluid; and a fluid outlet provided in between the first and second end of the housing body; and a piston provided in said cylindrical passage, said piston being axially movable between a first position wherein said fluid outlet is blocked by said piston such that the piston blocks the flow of fluid from the inlet to the outlet, and a second position wherein said outlet is not blocked by said piston and a fluid flow path is formed from the inlet to the outlet.

The present invention discloses a gate valve with a first side and a second side relative the throughbore. A circular body cavity is on the first side and a rectangular body cavity on the second side and a portion of the first side whereby the gate is operable to move up and down within the body cavities. Due to the rectangular body cavity, the seats are slimmer than the gate. A skirt assembly is used which is inserted over the gate to cover the gate opening when the gate is moved to the closed position to prevent debris and other contaminants from entering the body cavity. Four U-shaped seals are mounted to provide that the gate valve is a bidirectional gate valve with upstream sealing having back up downstream sealing in case an upstream seal fails.

A fluidic valve includes a valve seat, a valve sealing body placeable at the valve seat when the fluidic valve is closed and being displaced with respect to the valve seat when the fluidic valve is open, a force transmission element coupled with the valve sealing body, and an actuator mechanism configured for actuating the force transmission element for triggering the valve sealing body to carry out an additional movement different from an opening movement and a closing movement of the valve sealing body.

A valve stem arrangement for use in an adjustable choke, the valve stem being configured to prevent damage to components of the adjustable choke during downstream overpressure conditions. The valve stem generally connects a valve gate to an actuator for moving the valve gate within the choke. A set of shear screws couple components of the valve stem together. During overpressure conditions, the shear screws shear, permitting retraction of the valve gate towards an open position, thereby relieving loads on various choke components.
