Motorized valves use an electric motor to open or close the valve, making them ideal for large or remote fluid control applications. They work the same as manual valves, with the motor being the only difference. Different types of valves use different mechanisms, and motorized valves have electrical limits to prevent over-advancement. A motorized valve […]
Bicuspid aortic valve disease is a congenital birth defect where the aortic valve only has two leaflets instead of three, causing blood to flow back into the heart and potentially leading to symptoms later in life. Surgery is often required to replace the defective valve. The cause of the disease is not fully understood, but […]
A bicuspid aortic valve, which has two cusps instead of three, can be benign or lead to heart problems. It is often not noticed until later in life and may require antibiotics during dental procedures. Symptoms vary and can lead to aortic stenosis or regurgitation, which may require medication or surgery. The aortic valve, which […]
A foot valve is a check valve used with a pump to keep it primed and filter fluids. It allows fluid to flow in one direction and prevents air from entering the line. The valve is covered with a basket or cage to keep debris out, but it may need cleaning over time. Brass, plastic, […]
Valve actuators automate valve operation in industrial process industries. Hydraulic actuators are commonly used for butterfly valves, while electric actuators are used for gate valves. Linear actuators are used for control valves. Handwheels allow for manual control. Used in industrial process industries including water, oil and power plants, valve actuators provide automated operation of valves […]
A flanged gate valve has integral flange plates at each end, allowing it to be easily added to existing pipe flanges. It features a circular disc that controls fluid flow and is commonly used in industrial settings. The valve can be mounted by aligning the holes in the flanges and tightening bolts. It is typically […]
The ball valve is a ball-shaped in-line device with an orifice in the center that allows product to flow easily when oriented correctly. Flanged ball valves have mating connections or flanges that allow for quick and easy replacement. ASME regulations ensure interchangeability. The valves come in many configurations and are mostly used in industrial plumbing […]
Control valve actuators precisely position valves for adjustable control in the chemical process industry. Pneumatic actuators are preferred due to simplicity and low cost, but electro-hydraulic and electric actuators are also used. Valves can be air-to-open or air-to-close, and engineers must consider instrument air leakage for process safety. Manual actuators are cheaper but less accurate. […]
Zone valves regulate temperature in different areas of a building using hydronic systems. Each zone valve has a motor unit connected to a valve body, with electronic valves being common in homes. Large buildings use compressed air or vacuum-operated valves controlled by centralized systems. A zone valve can be used to regulate the temperature in […]
A gas valve regulates gas flow and is made of brass to avoid sparks. Gas fittings use a counter-clockwise thread to prevent unsafe valves from being installed. Bubble testing and Teflon tape ensure quality connections. Locking lugs and push-down valves are safety features to prevent accidents. A gas valve is a device used to regulate […]
A flow control valve regulates liquid or gas flow and can be mechanical or non-mechanical. Hydraulic mechanisms are used for automatic control valves, while external devices regulate others. Safety and altitude valves are examples of flow control valves. A flow control valve is a mechanical device used to regulate and control the flow of a […]
Fluid valves are used in piping systems to regulate and control the flow of hazardous or pressurized materials. They can be operated manually or electronically and are often used for isolation and maintenance purposes. Gauges and flow meters are commonly used in conjunction with fluid valves for monitoring and regulation. A fluid valve is a […]
A saddle valve is an inexpensive way to create a side stream from a main water stream. It consists of a clamp, tee, and stem. It’s used to supply water to appliances such as ice makers, coolers, filters, and humidifiers. The valve is installed on a nearby cold water line and the position is chosen […]
A saddle valve is a cheap way to create a side stream from a main stream of water, often used to supply water to appliances. It consists of a two-piece clamp, a tee, and a stem that opens or closes the valve. Self-tapping saddle valves have a screw-like point that pierces the tube. The valve […]
A thermal expansion valve regulates refrigerant pressures in air conditioning and refrigeration systems. It controls the varying levels of refrigerant as the temperature changes and is where liquid is released to become a gas and start the cooling process. The valve includes a thermal bulb that expands and contracts with temperature changes, allowing more or […]
Ball check valves allow material flow in one direction using a spring-loaded ball inside a valve body. They are simple and used in fuel and water pumping systems. They can be made of metal or ruby, and some have replaceable internal components. Double ball check valves prevent backflow contamination. A ball check valve is one […]
A valve cone is a component of a cone valve that can be dynamic or fixed. Dynamic cones control fluid or gas flow by adjusting the cone’s position, while fixed cones affect flow by forcing it around the cone. Different types of cone valves are used in plumbing and drainage systems. A valve cone is […]
A valve cone is a component of a cone valve that can be dynamic or fixed. Dynamic cones regulate fluid or gas flow by being raised or lowered, while fixed cones affect flow by restricting it and causing dispersion. Cone valves are used in plumbing and drainage systems. A valve cone is the defining and […]
Seismic valves automatically shut off natural gas service during an earthquake to prevent gas leaks and potential fires or explosions. They are mandatory in some regions and can be installed in the pipeline leading to a facility. Overflow sensors and methane detectors are also used as precautions. Gas appliances should be docked and gas meters […]
Choosing the best check valve depends on materials needed and ease of maintenance. Materials must be compatible with the product and valves should quickly stop reverse flow. Different types of valves have varying pressure drops and maintenance requirements. Regular testing and disassembly for cleaning may be necessary. Choosing the best check valve, that is, a […]
