To prevent nuisance marine growth in a valve, particularly a ball valve, used to regulate a flow of seawater, a compound for lubricating and preventing nuisance marine growth is provided in the valve. The nuisance marine growth preventing compound includes a substantially uniform mixture of marine grease and an antifouling agent. The compound is introduced into the valve such that the compound is provided between and contacts a valve body and a ball that regulates the flow of seawater within the valve, and inhibits nuisance marine growth at a space between the ball and the valve body which is occupied by the compound.

Disclosed herein is a valve apparatus for vehicles that is configured such that the sealability of a valve body can be markedly enhanced. The valve apparatus includes a valve body, a valve member and a sealing unit. The valve body is provided with at least two ports and has an internal space communicating with the ports. The valve member is rotatably installed in the internal space so as to open or close the ports. The sealing unit is provided to seal at least one of the ports. The sealing unit includes a sealing body airtightly installed on an inner surface of the corresponding port, and at least one elastic element integrally provided on a first end of the sealing body. The elastic element axially applies elastic force to the sealing body so that a second end of the sealing body comes into airtight contact with the valve member.

A valve actuator includes a motor, an AC power source, a DC braking system, and a control system. The control system is configured to control the AC power source to apply an AC voltage to the motor to drive a valve toward a closed position. The control system is configured to disconnect the AC voltage from the motor before the valve reaches the closed position. The control system is configured to control the DC braking system to apply a DC voltage to the motor to stop motion of the valve.

A Centering Electronic Rotary Valve (CERV) includes an adapter structure having an arcuate shaped adapter top interface portion and an arcuate shaped adapter bottom interface cavity, wherein the adapter structure defines an adapter input channel and at least one adapter output channel. The CERV includes a stator structure having an arcuate shaped stator top interface portion and an arcuate shaped stator bottom interface cavity, wherein the stator structure defines a stator input channel and at least one stator output channel, wherein the stator input channel is aligned with the adapter input channel and the stator output channel is aligned with the adapter output channel. The CERV includes a rotor rotatably associated with the stator and having a rotor channel that communicates the stator input channel with the stator output channel.

The disclosure relates to a container cap valve dispenser that may be assembled to a 5-gallon bucket and/or bulk container lid for ease of use of dispensing liquids and flowable solids such as paint, soap, coffee, etc. The device is a two-piece valve assembly that embodies at least one type of valve means of fluid control. It comprises, but is not limited to a valve assembly that includes a ball assembly, a valve body and a container cap and/or end connection. The ball assembly may rotate with respect to the valve body to open or close the valve with the use of a valve stem and/or handle. The device is configured to disassemble and reassemble as needed.

A valve can include a valve body, a rotatable gate, a neck extending from the valve body, a shaft extending from the rotatable gate and through the neck, and a seal assembly configured to rotatably seal the shaft to the neck. The seal assembly can include a first stage seal having a first working temperature and coupled to the shaft at a first stage seal location, and a second stage seal having a second working temperature and coupled to the shaft at a second stage seal location farther from the valve body than the first stage seal location. The first working temperature can be higher than the second working temperature, and the seal locations and the first stage seal can be configured to prevent a second stage operating temperature at the second stage seal location from exceeding the second working temperature.
