What is a four -way valve?
The four -way valve uses a number of ports to control fluid flow in different directions using a single valve. The design can have a single input port with three development ports or two input and output ports for control of flow from two different sources. These valves can be manually operated or powered by air, hydraulic fluid or electricity. Three output ports for different storage tanks or piston control on a hydraulically operated device can be connected to the discharge pipe. The valve can have a hand control arm or a powered engine or drive for moving the valve assembly. The internal valve ports open and close and broadcast the liquid in the desired direction. The internal design can allow two fluids to be moved at the same time or one flow of fluid can be opened and the other is closed. The valve dual port control can be manual or powered, in the same way as one port.
There are a number of possible applications for a four -way valve. Industrial aboutGovernment elements use them to open and close other valves to feed chemical processes. They can be used to control steam flow to heated equipment or buildings. A hydraulic four -way valve can control a design device such as soles or cranes, opening, closing or moving devices with hydraulic pistons.
Air conditioning systems use a four -way heat pump valve. The heat pump extracts heat from the outside and releases it inside the building. In heating mode, the valve reverses the flow of refrigerant with indoor and outdoor coils. The discharge gas from the compressor is sent to the inner coil and the heat is extracted to warm the interior. Switching the thermostat to cooling will move the valve, the achoolet will flow in the direction needed to cool the interior.
pools may contain four -way valves to control water flow for filtering, discharge and flushing. They turn offThe pool pumps will usually flow through the pool filter to clean the water. Changing the four -way valve to the drain position can allow the pool level or the pool drained. The third position on the valve will send water in the opposite direction through the filter to stretch the filter medium. Four -way valves can reduce the cost and complexity of the pool system by allowing one pump to provide multiple functions.
