Vacuum relief valves prevent damage to piping systems caused by vacuum forces. They open when pressure drops dangerously low, allowing materials such as fluids, gases, and air to compensate for the pressure drop. Valve materials match those of the piping system for proper sealing. Vacuum relief valves are installed within systems that have a significant […]
A valve room is a separate facility that houses valves connected to inverters in a plant. It maintains ideal temperature and humidity for efficient valve use and is built to withstand severe weather conditions. It includes electrical systems and may have heating and cooling equipment in an adjacent facility. Valve room is a term used […]
Light valves, such as liquid crystal (LC), digital micromirror device (DMD), and light grid valve (GLV), reflect or allow light to pass through. LCs polarize light and are used with a polarizer, while GLVs modulate diffraction of light. DMDs use hinge-mounted arrays of microscopic mirrors to turn on or off, with one chip for each […]
Valve float occurs when lifters fail to follow the camshaft profile due to weak valve springs, causing misfires and power loss. It can damage the engine and lead to catastrophic failure. Stronger springs and advanced cam profiles can help eliminate valve float in racing engines. When an internal combustion engine experiences valve float, the lifters […]
A solenoid valve coil uses a wire wound around a ferromagnetic core to create a magnetic field that moves a valve plunger. It can operate on different voltages and is available in various constructions. Different configurations include tape-wrapped, encapsulated, and connector types. A solenoid valve coil, which typically has copper or aluminum wire, is often […]
A compressor moves air, gas or liquid through a machine’s components. Superchargers use a cylinder chamber with a piston that changes pressure to move air through the machine. Compressor valves control the flow of air, with intake valves allowing substance into the cylinder and exhaust valves controlling the flow out. Different types of compressor valves […]
Ball valve actuators are mechanical devices used to remotely or automatically open and close ball valves. They are part of a family of quarter-turn actuators and are powered by electric motors, compressed air, or oil. Ball valves are commonly used in various industries and require only a 45-degree turn to open or close. Ball valve […]
Thermal valves respond to temperature changes, assisting high-pressure machines and preventing breakdowns. There are two types: expansion and exhaust. They increase efficiency and safety, found in household items and industrial machines. Expansion valves use a temperature-sensitive bulb to adjust coolant flow, while safety valves have a spring to control gas release. A thermal valve is […]
Pilot valves control fluid flow in various systems, with some equipped with a dead man’s switch for safety. They work through self-cleaning orifices and can reduce pressure to prevent pipeline rupture. Another type controls gas flow to appliances, maintaining pressure and flow balance. A pilot valve is a valve that controls the flow of some […]
A shuttle valve allows two fluid inlets to flow to a single outlet, used for mixing or alternating materials. It can provide backup fluids during emergencies and is commonly associated with hydraulic fluid or compressed air. Different types exist, and factors such as size, pressure, and temperature must be considered when selecting one. They are […]
A relief valve relieves excess pressure in pneumatic or steam lines, preventing dangerous explosions. It is adjustable and rebuildable, and some emergency valves require manual resetting. Machines like air compressors and pneumatic presses use relief valves to operate safely. Steam engines also use relief valves to prevent overpressure. A relief valve is a device used […]
A reversing valve directs refrigerant flow in a heat pump, allowing it to function as both a heating and cooling system. It works by reversing the roles of the evaporator and condenser. Reversing valve failure is common and should be repaired by a professional. A reversing valve is an important element within a heat pump […]
Pneumatic valves use compressed air to open and close, and can be manually operated. They are designed for specific applications and can be customized. They are typically made of lightweight materials and are used in low pressure applications. Pneumatic valves are popular for supplying power to different parts of a machine and can control the […]
Float valves control fluid levels in tanks by opening and closing a valve in response to changes in the fluid level. They are used in toilets, animal waterers, plant watering systems, and aquariums. The basic valve includes a balloon float attached to an arm that closes the valve when the water level rises. The valve […]
A four-way valve controls fluid flow in different directions using a single valve. It can have one inlet and three outlet ports or two inlet and outlet ports. They can be manually operated or powered by air, hydraulic fluid or electricity. They are used in various applications such as industrial controls, air conditioning systems, and […]
Rotary valves use a rotating circular seal to change the path of liquids or gases, taking up less space than linear valves. They are used in plumbing, manufacturing, combustion engines, musical instruments, and the human body. Examples include ball valves, butterfly valves, and rotary feeders. Some combustion engines use a sophisticated type of rotary valve […]
A flapper valve is a simple one-way valve that prevents fluid or gas from flowing back into the tube. It has many applications and is easy to maintain, making it an attractive option for remote areas. The valve is remotely operated and comes in various sizes and designs. The flap component can be made from […]
A flapper valve is a one-way valve that allows fluid or gas to flow in one direction and prevents flow in the opposite direction. It is simple, efficient, and easy to maintain, making it ideal for various applications. The valve is remotely operated and comes in different sizes and designs. The flap component can be […]
Water solenoid valves control the flow of water through a piping system using a piston or tappet valve and a solenoid coil. When the solenoid is activated, the valve opens, allowing water to flow through. They are used in smaller water supply systems and can be made of various materials. Solenoids are typically mounted on […]
A solenoid valve is activated by electricity and becomes a hydraulic solenoid valve when fluid is introduced. They are used in various applications and can be powered by AC or DC. Different types are not interchangeable. Replacement varies based on the application. A solenoid valve is a voltage actuated valve, which means that it is […]
