Isolation Valves: Ball, butterfly, diaphragm, gate, pinch, piston, and plug valves. Regulation Valves: Ball, butterfly, diaphragm, globe, needle, pinch, and plug valves. Safety Relief Valves: Pressure release and vacuum relief valves. Non-Return Valves: Swing check and lift check valves.
The most prevalent forms of automated valves can be divided into three groups. They are self-actuated, linear, and rotating. Within each of these categories, there are a multitude of valve types, each with its own set of advantages.
A butterfly valve is a type of valve in a piping system or an air management system that has a disc-shaped flap that can be rotated by hand. The valves are usually mounted on pipe or ducting, and they may be used to regulate the flow of fluid, air, steam, or gas.
An HVAC system uses a pump to move water through its pipes. The pump can be powered by electricity or an engine, which is connected to a power plant. In order for the pipes to be cleaned, the pressure level must be maintained within certain parameters. This means that when air is pumped into a room, it must be forced through the pipes at high pressure.
The flow of water in pipes is controlled by HVAC valves. Valves govern the flow of water, gas, and air in major components of an HVAC system such the water chiller, cooling water pumps, air handling units, and fan coil units.
