There are two primary methods used within hydraulic valves. Some control hydraulic fluid flow by using a spool, bore and different ports, while others use one or more poppet valves. Both of these types of hydraulic valves are designed to control or change the direction of hydraulic fluid flow.
inside the valve is a ball with a hole cut right through the center this ball is connected to the handle when the part with the hole is parallel with the pipe itself the water flow is unrestricted and flows freelyhe gate valve has much the same function as the ball valve in that it is used to restrict the flow of water only the gate valve is generally used for larger applications again the name explains the function
