What is a diverter valve?
A diverter valve is a type of processing valve that allows you to control or direct flow from one inlet to one of or more outlets. This provides a simple way to add auxiliary components to your system. Diverter valves are also great for flow control and converging two lines into one. They are mainly used for handling powders, slurries, and dry solids. Handling liquid service is also possible for some types of diverter valves.

What is a diverter valve and its parts?
Valve Body
This is the main part (usually of steel or aluminum) that houses, holds, and maintains the internal components. The valve body of a diverter valve is usually constructed to resist hydraulic pressures. The body has partitions or dividers that support the internal parts.
Spool
The spool is an internal component that moves within the valve body to regulate the flow of hydraulic fluid. It often has a variety of channels (or ports) fabricated into it. The spool shifts positions in order to control which channels are open or closed. Thus diverting the flow to different outlets.
Bonnet
The bonnet is the external part of the valve that acts as a cover to the valve’s orifice. It can be solely a cover to seal and sometimes support and protect the internal components like seat, disk, and stem keeping them in place.
Actuator
The actuator of a diverter valve runs the disk properly. It also runs the assembly. The actuator can be manually operated or by the solenoids, levers, motors, and pneumatic operators. They are typically positioned outside the diverter valve’s pressure boundary.
Ports
The inlets and outlets of hydraulic fluids in the valve body. The ports are the entry and exit path where fluids can enter and leave. The number of ports and the configuration is dictated by what type of application the diverter valve is going to be used for.
Seat
Sometimes it’s called a seal ring and it is one of the internal components of a valve that comprises the trim. The seat holds and maintains the disk in place.
Springs
The spring is used to return force assisting in the positioning and movement of the diverter valve’s internal components. They ensure the valve returns to its normal position or state by providing balanced force and supporting actuation mechanisms.
Disk
The disk opens or closes the flow path directing and diverting fluid flow to the appropriate outlet by seating against a valve seat. It is also considered as the trim component giving the shape of the diverter valve. The disk is also essential when it comes to the modulation of flow rates of water through the pipes by adjusting positions. Disks also assist with pressure control by flow regulation of different outlets.
Stem
The stem connects the actuator (manual or automated) to the internal moving components of the valve (the disk or spool). Its main function is to transfer force from the actuator enabling control of the valve’s operation. The stem also allows linear or rotational movement of the disk (depending on the valve design) regulating the flow of hydraulic fluid.
Packing
The packing separates the internal parts and external components protecting them from potential damage-causing actions. This may be made of a variety of materials and it also holds and maintains against leaks.

Tub Diverter Valve
The tub diverter valve’s function is to redirect the water from the tub spout to the showerhead. What is a diverter valve and its types? Without further ado, here are the three types of tub diverter valves:
Three-valve Diverter
The three-valve diverter is found between taps of a two-tap faucet. The water (from the hot and cold faucets) is set to the right temperature then a third faucet (or lever) is engaged. The third faucet (lever) diverts the water through the valve and out through the showerhead.
Two-valve Diverter
The two-valve diverter is found in the center of the faucet having two L-shaped valves. The water temperature between the taps of a two-tap faucet is adjusted by a single dial or knob. The water is directed from the bath tub spout to the showerhead by turning the handle.
Tee-diverter
The tee-diverter is a plain valve that is a part of a tub faucet. It has a straight handle that directs water to the showerhead when you pull up.
Shower Head Diverter Valve
The Shower Head Diverter Valve is made for multiple shower heads and is usually found in gyms or pool showers, or any place where more than one shower head is fitted in the bath.
What is a diverter valve and the other types?
These are specialty diverters like a diverter valve pool or a 4-way shower diverter valve used in pool plumbing or specialty shower fixtures.
What is a diverter valve and its functions?
Here are the functions of diverter valves in hydraulic systems:
Flow Control
What is a diverter valve in flow control? Diverter valves aid in controlling the movement of hydraulic fluid in a way that you can actually manipulate or control the amount of liquid sent into the different components in a system. The diverter valve plays an essential role when it comes to controlling the actuators, motors, or cylinders to manage their velocity and force.
Directional Control
As diverter valves direct the flow of hydraulic fluid, they then supply movement direction in a hydraulic cylinder. Directional control plays a crucial role in controlling different components of a machine or system.
Component Isolation
What is a diverter valve when it comes to component isolation? Diverter valves permit the isolation of particular hydraulic components or circuits. This allows channeling fluid through a set of components while keeping another inactive or idle. This is most crucial for effective and efficient optimization of the functioning of complex hydraulic systems.
Function Sequencing
What is a diverter valve and its essence in function sequencing? There are systems that use diverter valves in order to sequence different hydraulic operations. Through control of the sequence in which hydraulic components are activated or engaged, a diverter valve aids to sequence different hydraulic operations.
Pressure Regulation
There are particular types of diverter valves that control and regulate the pressure level in hydraulic systems. These types of diverter valves may use pressure relief mechanisms in order to ensure that the system is protected from conditions of overpressure.
Hydraulic Power Distribution
Diverter valves allocate power effectively by channeling the flow of hydraulic fluid to parts that need it most immediately. This guarantees that the different sections of such a system receive enough amounts of power to ensure proper functioning.
Emergency Operation
What is a diverter valve and how does it help in certain emergencies? Emergency operations can be one of the applications for diverter valves. Diverter valves allow manual or automatic bypass of the hydraulic fluid in case of system failure or emergency.
Multi-functional Control
What is a diverter valve and its multi-functional control? Numerous hydraulic systems in different machines have dual functionality. Diverter valves are important in systemizing and controlling these functions by allowing the operator to change different aspects of the operations.
Aside from disadvantages mentioned above, if there is small leakage and it is some distance away, there may not be enough differential pressure to move the shuttle.
