Solenoid valve actuators use an electric current to open or close valves, and are used in remote or continuous control situations. They can control various types of valves, from simple quarter-turn ball valves to complex control valves. The actuator contains an electromagnet that moves a control arm or valve stem. In explosive or flammable environments, […]
A globe valve controls or stops liquid or gas flow through a pipe with a disc or plug closing the seat. It can handle flow in either direction and can be sealed using an actuator. It restricts flow and offers good control. It can close with or against product flow and causes a pressure drop […]
A double check valve prevents back siphoning and contamination of fresh water supplies. It consists of two non-return check valves mounted in one housing for redundancy and efficient seating. Backflow contamination is a major source of freshwater contamination, and check valves rely on a spring- or gravity-loaded plunger or diaphragm to allow fluids to flow […]
Hydraulic valves control liquid or gas flow in pipes and are made of metal or thermoplastic. Plumbers use different techniques to join pipes and valves, and local building codes govern their size and materials. Gate and globe valves are common types, and some valves have additional devices for special functions. A hydraulic valve is a […]
Dump valves rapidly release material and can be fitted to various devices for safety reasons. Relief valves are used to manage pressure and discharge hazardous loads. They can be custom-designed and fitted with filters. Blow-off valves maintain safe pressure levels in turbocharged cars. Relief valves are labeled with instructions for easy use in emergencies. Trained […]
A lever valve is a simple device used in plumbing systems to shut off the flow of liquid, gas, or sewage. It consists of a lever, valve housing, and a ball. Lever valves are ideal for emergency shutoffs and require only a quick 90-degree turn to shut off the flow. They are also easily visible […]
A master valve is an automatic valve installed near the main water line of an irrigation system to prevent water leakage from leaky zone valves. It opens and closes with the zone valve and can cause premature failure of plastic pipes. A flow sensor can further reduce water losses caused by leaks. A master valve […]
A thermostatic mixing valve (TMV) mixes hot and cold water safely, prevents scalding, maintains a constant temperature, prevents bacterial growth, and has built-in safety mechanisms. TMVs are used in central heating systems, controlling water temperature in buildings, and individual taps. They prevent sunburn by creating a uniform blend of water and don’t rely on water […]
Irrigation valves regulate water flow in sprinkler systems for parks, golf courses, and home lawns. Globe valves are common in commercial systems, while anti-siphon valves are used in residential applications. Plastic and brass materials are used to make valves. Multiple sprinkler valves allow water to reach different areas at different times, and a master valve […]
Diaphragm valves use a flexible membrane to control flow and can be powered by air, solenoids, or hydraulics. They come in two types, weir and straight, and are used in various industries. They can be made from plastics or metals and are named for their uses. A diaphragm valve is a control device that uses […]
A diaphragm valve uses a flexible membrane to control the flow of gas, fluid, or sewage. It can be operated pneumatically, hydraulically, or manually and can be made from various materials. There are two types of diaphragm valves: weir and straight. They are used in various industries and applications, including sprinkler systems and paintball guns. […]
A pneumatic solenoid valve uses electrical energy to open a valve under positive or negative air pressure. It works through electrical induction and can act as a safety valve in industrial systems. They come in different sizes and complexities, with some controlling multiple inlet and outlet ports. A pneumatic solenoid valve is a type of […]
A pneumatic solenoid valve is an electromechanical device that opens a valve under positive or negative air pressure. It works using electrical induction and can be used as a trigger for larger solenoids. They are often used in automated industrial plants and come in various sizes and complexities. They can withstand high pressures and temperatures. […]
A shunt valve is used in a ventriculoperitoneal (VP) shunt to treat hydrocephalus. The valve regulates the flow of cerebrospinal fluid (CSF) from the brain to other parts of the body. There are two types of shunt valves: adjustable and fixed pressure. The neurosurgeon chooses which type based on the patient’s condition. Symptoms of excessive […]
An overflow valve maintains pressure in pipes and can act as a safety device. It senses pressure and has a coil spring mechanism to regulate it. It’s important to select the appropriate valve, install a safety shutoff valve, and protect from particulate matter. Shutoff valves should be placed upstream and downstream, with a bypass line […]
Mitral valve collapse is a common heart valve problem that causes blood to flow backward, known as mitral valve regurgitation. It can be caused by two malfunctions in the valve flaps and is diagnosed through listening to the heart or using an echocardiogram. Symptoms are often benign, but severe cases may require surgery or beta […]
Pressure relief valves are safety devices that prevent dangerous pressure buildups in pressurized systems. They can be set to open at a specific pressure or temperature and are required by law for safety reasons in many regions. A classic example is the valve fitted to a water heater that “vents” if the temperature or pressure […]
An expansion valve, typically a thermal expansion valve, is used in HVAC systems to reduce pressure. There are two types for air conditioners: thermostatic expansion valves and capillary tubes. The valve is part of the evaporator and is necessary for the cooling process, which involves the use of refrigerated gas passing through coils and an […]
An expansion valve reduces pressure in HVAC systems. The two main types are thermostatic expansion valves and capillary tubes. The valve is part of the evaporator and is necessary for the cooling process to work efficiently. An expansion valve is a piece of equipment that reduces pressure in a system. The most common form of […]
Motorized valves use an electric motor to open or close and are ideal for large or remote fluid control applications. They have the same internal mechanisms as manual valves, with the only difference being the inclusion of a motor and gear assembly. Rotary motorized valves have the fastest actuation times and are commonly used on […]
