A ball valve is defined as a quarter-turn valve with a spherical closing element held between two seats. Because of their quick opening and good shut-off characteristics, ball valves are widely used as on/off valves in chemical processing and other industries. Ball valve body designs are typically one-, two-, or three-piece, or all-welded. Larger valves with heavier balls (e.g. - on pipelines) may use trunnions to help support the ball and prevent damage to the soft internals. These valves are also available in a double block and bleed configuration.
A butterfly valve is a quarter-turn valve which has a circular disc as its closing element. The standard design has the valve stem running through the center of the disc; later designs offset the stem so that the disc &#;cams&#; into the valve seat. Advantages include less wear and tear on the disc and seats and tighter shut-off capabilities. Many design types are available, including inexpensive Teflon or resilient seats for use in water (treatment) plants, etc. More expensive metal seats can be used where high temperatures or aggressive chemicals are encountered. So-called &#;high-performance&#; butterfly valves offer zero-leakage designs and have been applied in both the chemical and hydrocarbon processing industries.
Some special designs are also available for specific applications:
A plug valve is a multi-purpose valve is designed to operate in the fully open or closed position. They are used in chemical, petrochemical, pulp and paper, pharmaceuticals, fossil fuel, nuclear power, water treatment and purification systems. Some special applications would be hydrofluoric acid, fire safe, chlorine service, sampling, leak detector, buffer systems, converging and diverging applications and oxygen service.
The basic style is the two-way plug valve, which allows the flow to move normally from left to right or vice-versa. Other configurations are the three-way, four-way, and five-way designs, which would allow mixing, converging, and diverging of flows. These valves are also available in a double block and bleed configuration.
Plug valves are manufactured with lubricated or non-lubricated designs. The lubricated design is sealed with grease (lubricant), whereas the non-lubricated design is sealed with a resilient sleeve, fully retained around the top, bottom, and around the ports. They can be ordered in full or reduced port, operated by lever, gear, or power source, and in many various materials suitable for most applications.
Gate valves are the most common of all commodity valves. It derives its name from the gate-like closure element, which operates in a perpendicular plane to the flow stream. Mainly used in industrial piping, this valve is designed strictly for a fully open or a fully closed operation. Although normally handwheel operated, they can be easily adapted for bevel gear, electric motor, or cylinder actuators. The gate valve exhibits low resistance to flow because of its straight-through flow path and is used where minimum pressure drop (ΔP) and bi-directional flow are required. Many various materials for body and trim combinations can be specified to comply with almost any on/off service.
A globe valve is designed to regulate or throttle flow. The closure element of a globe valve is a plug that can be of many various shapes and forms; popular shapes include a flat disc, conical, parabolic, and spherical. Each design is tapered differently to perform a liner, quick-opening, or equal percentage flow characteristic in relation to flow calculations. The tortuous flow path is parallel to the seat, requiring tremendous closing torques with the larger globe valves due to its unbalanced trim design. Therefore, the size of globe valves is usually limited to the nominal size of 12 inches. Because of the change of the flow path through the valve, this valve causes high resistance to flow.
A safety relief valve is a quick-opening valve using a diaphragm plate with an adjustable spring set at the relief pressure. When the pressure reaches a set point, the valve opens and alleviates critical overpressures in a pipeline that could cause severe damage, including explosions.
They are designed in a variety of types and sizes, and are used in a variety of industries. They are important part of any safety system that helps prevent accidents.
