The thread ball valve with brass and stainless steel material is used for the garden hose. The ball valve for garden hose is a quarter turn valve that to check the flow through, using a sphere with holes and turns. The hole of the sphere is off when it is flush with the flow and rotated 90 degrees by the valve arm.

Electric actuated butterfly valve is generally used in environmental protection, food, light industry, oil and other industries,electric butterfly valve is also used in HVAC and refrigeration industry, but also can be used in the industrial field and water treatment, electric actuated butterfly valve is widely used because of its own advantages, but there are advantages and disadvantages.

The stainless steel flanged ball valves produced by milestone valve company have two-piece and three piece valve body structures. The middle flange is connected by bolts and the seal is made of nickel base alloy. There is no PTFE bearing on the upper and lower valve stems to reduce friction and save labor. There is no adjusting plate at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Stainless steel flanged ball valves can be used for strong electrolytes, organic solvents, acids, gas and other general working materials, as well as standard end materials, such as CO2, hydrogen peroxide, methane gas, butadiene and so on.

Wafer type butterfly control valve are used for isolating and regulating flow. The closing mechanism is a disc that allows for quick shut off, much like a ball valve. Wafer type butterfly control valve are light in weight so they require less support. Unlike the ball valve, the disc is always present within the flow, therefore a pressure drop is always induced during flow, regardless of valve position. The disc is typically rotated a quarter turn when the valve is fully opened, but the valve may also be opened incrementally in order to throttle flow.

A water main gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A water main gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve. The seat and the gate together perform the function of shutting off the flow of fluid.

Thread Ball valve in the pipeline is mainly used to cut off, distribution and change the flow of media, it only needs to rotate 90 degrees of operation, small rotation torque can be closed tightly.When fully open or fully closed, the sealing surface of the ball valve and valve seat is isolated from the medium.
