Valve

A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Ball Valve

A ball valve is a flow control device which uses a hollow, perforated and pivoting ball to control fluid flowing through it.

A ball valve is a shut-off valve that allows, obstructs, and controls the flow of liquids, gases, and vapors in a piping system by rotating the ball having a bore inside the valve. The ball is mounted against two seats and has a shaft that connects it to the operating and control mechanism that rotates the ball.

Butterfly Valve

A butterfly valve is a valve that isolates or regulates the flow of a fluid.

The closing mechanism is a disk that rotates. Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow.

Check valve

Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.

Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns, the valve will close to protect the piping, other valves, pumps etc.

Control Valve

A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller.

Control valves are used in many processes to control flow, pressure, temperature or other variables. The type of valve used will depend on the size of the pipe, the overall pressure that the system operates, the flowing media, process conditions, and other factors.

Cryogenic Valve

Cryogenic valves are kept in a natural closed position to keep cryogenic gasses or other medium secure and safely contained.

In the oil and gas industry, cryogenic valves serve in the control of liquified gasses such as liquid nitrogen, methane, and helium. Because of the ease and safety of non-pressurized storage and transport, these elements cool to cryogenic temperatures, so they remain in the liquid state.

Gate Valve

A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid.

A gate valve is the most common valve for water supply systems. It represents a linear-motion isolation valve and has a function to stop or allow the flow. Gate valves got their name from the closure element sliding into the flow stream to provide shutoff and, therefore, acting like a gate.

Globe Valve

A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body.

Unlike the gate valve, globe valve can be used for regulating flow or pressures as well as complete shutoff of flow. It may also be used sometime as a pressure relief valve or as a check valve. Compared with a gate valve or ball valve, the globe valve has considerably higher pressure loss in the fully open position.

What are valve standards?

Many kinds of valves are used in the industrial process, and to ensure proper functionality, compatibility, and safety for end-users, EPC, or engineering, every country has particular organizations to make standards.

The major standard organizations include the American National Standards Institute(ANSI), American Petroleum Institute(API), The American Society of Mechanical Engineers(ASME), British(BS), China valve standards(GB, JB, HG), and so on. THINKTANK provides standard resources for all interesting valves friends study.
