A gate valve is a cheaper alternative to a ball valve, although by only a few dollars. Depending on the size, a gate valve costs around $5 and a ball valve is usually under $10.

Both types of valves have the same purpose, which is to control the flow of water. The design of each, however, is vastly different.
A gate valve has a round knob on top that you turn. This motion raises or lowers a gate inside of the housing to stop or start the flow of water. These valves are prone to failure as they age because they can corrode.

A ball valve is a man among boys. Instead of a knob, it uses a lever. This valve has positive stops machined in that allows the lever to move only 90 degrees. When the lever is parallel to the pipe, the valve is open and water will flow. If the lever is perpendicular to the pipe, the valve is closed.
If you were to cut a ball valve open, you would see that the lever is connected to a ball with a hole bored through the center of it. This is where the water passes through. Turning the water on and off is only a matter of throwing the lever 90 degrees.

Because of the round handle on a gate valve, it’s hard to tell if the valve is open or closed, and when the valve is broken, you end up turning the knob one way and then the other without accomplishing anything. In some cases, the gate will corrode and separate from the lifting mechanism and drop. It will come to rest at the bottom of the valve and cut off the flow of water.
The long and short of it is if you are going to replace the valve, spend a few extra dollars and install a ball valve. water filter

This sediment prefilter housing and cartridge is designed for 1″ main water lines, with 15 gpm peak recommended flow. The replaceable pleated cartridge removes sediment, silt, sand, dirt and cysts down to 1 micron (lasts about 6 months). Housing accepts any industry-standard 9 3/4″ long by 4 1/2″ diameter cartridges. Inlet and outlet are 1″ female pipe threads.

The Melt blown micro-fiber is self-bonded and formed a 3D pore structure. Diameter and density of micro-fiber can be varying from inner to outer of the filter diameter. Melt Blown Depth water filter Cartridges is designed to have continuously graded pore structure provide both pre-filtration and final-filtration.

We are supplying different kinds of water filters, ball valve, the countertop filter series are made from AS and ABS, they are suitable for the family,hotel and restaurant.You can choose proper water filter cartridges. Proper water filter cartridge can remove odor, smell, color, and even organic chemicals. And the water filters can be assembled in different stages, such as 3 stages and 5stages as usual. It is depended by the people requirements.

• In reduced port ball valves, flow through the valve is one pipe size smaller than the valve’s pipe size resulting in flow area becoming lesser than pipe. But the flow discharge remains constant as it is a Multipler factor of Flow discharge(Q) is equal to Area of Flow (A) into Velocity (V). A1V1=A2V2 i.e the Velocity increase with reduced Area of flow and Velocity decreases with increased area of flow. Bibcocks

• A V port ball valve has either a ‘v’ shaped ball or a ‘v’ shaped seat. This allows the orifice to be opened and closed in a more controlled manner with a closer to linear flow characteristic. When the valve is in the closed position and opening is commenced the small end of the ‘v’ is opened first allowing stable flow control during this stage. This type of design requires a generally more robust construction due to higher velocities of the fluids, which would quickly damage a standard valve.

• A trunnion ball valve has a mechanical means of anchoring the ball at the top and the bottom, this design is usually applied on larger and higher pressure valves (say, 4″ and above 600 psi and above).

Pressure Reducing Angle Valve made of cast brass can be adjusted to restrict pressures up to 175lbs. Locking pin device restricts full opening of valve by untrained personnel. Pin may be removed by fire personnel to allow full open valve.

Gate Valve made of cast brass for use on standpipes, fire pumps or hydrants. Has a straightway pattern, non rising stem and is rated at 300lbs.

Single Hydrant Gate Valve made of cast brass for use on standpipes, fire pumps or hydrants. Has a straightway pattern, non rising stem and is rated at 300lbs. U.L. Listed and FM Approved.
