What is a ball valve?
A ball valve is a type of quarter turn valve that uses a rotating metal ball with a hole in the middle to control the flow of liquid or gas within a system. Ball valves are often used in industrial applications due to their simple design, low cost, and reliability.
The operation of a ball valve is based off the concept of an on/off switch, it can be opened to allow flow and closed when no flow is required. This can be achieved by using different types of handles such as levers or cranks which rotate the ball’s position inside its cavity from 0° (closed) to 90° (open). The position indicator on some designs also allows for easy visual confirmation whether the valve has been left open or closed after operating.
What is a ball valve used for?
A ball valve is a quarter-turn valve that functions as an on/off switch for the flow of fluids and gases. It consists of a hollow, perforated sphere which is connected to two outlets and passes through an actuator handle. This handle controls the opening and closing of the valve by turning the ball inside. Ball valves are used in residential, commercial, industrial, agricultural, medical and many other applications due to their simple design compared to other valves available on the market.
Ball valves find use in simple shut-off applications such as controlling water flow from faucets or toilets; they can also be found in larger pipe systems where precise control over pressure or flow are needed such as controlling pumps or regulating cooling systems in industry processes.
The flexibility of this type of valve lies largely with its construction: since it operates via a quarter turn operation – making them much simpler than gate or globe type valves – they provide excellent sealing capabilities when closed over long periods without any deterioration.
Furthermore they allow for tight shut off with minimal maintenance over time due to their single moving part than can easily be accessed during service intervals if necessary. When open however their unique body design ensures flows remain low turbulence meaning less pressure drops across them meaning more efficient operation cycles with lower operating costs overall.
What is the ASME standard for ball valves?
The American Society of Mechanical Engineers (ASME) sets the standard for ball valves used in various industries. The ASME B16.34 is a standard that covers ball valves, butterfly valves, and check valves with flanged or butt-welding ends. This document provides guidelines for materials, dimensions, pressure ratings, testing requirements and other design parameters related to the manufacture of these products for use in both commercial and industrial environments.
What is the API standard for ball valve?
API Standard 6D is the globally accepted standard specification for ball valves used in the petroleum and natural gas industries. The standard mandates specific requirements that must be met for a ball valve as regards performance, testing, design and materials.
Performance requirements include quality factors such as operating pressure-temperature ratings, valve strength tests (excess torque), leakage rates of both sides of stem seal rings under both static and dynamic conditions, sealability against gas/liquid at varying pressures. It also sets maximum allowable limits on body seat tightening torque and hardness surface roughness Ra value which are essential to producing good sealing effect between body nose seat & ball plug cavity.
