FREE-VALVE's flange foot valve is a kind of energy saving valve, usually installed at the bottom of the suction pipe of pump. The functions of foot valve are designed to stop water from going backwards when the pump shuts off and only allow the water flow forward . As many inlet and stiffeners are designed on the valve bonnet , the valve is not easy to clog . The foot valve is usually applied at suction pipe . The valve disc usually designed as signal disc ,and connection method is flange . Features 1.Flange foot valve is composed of valve body, disc, cover,strainer basket, sealing ring and other parts. 2.The disc is moved up and down under fluid pressure drop between inlet and outlet to realize the valve opening and closing. The valve opens under the pressure of the fluid. 3.When the pump stops working, the valve will be shut off quickly under pressure of outlet pipe , and the liquid will not flow back to the water source, which will help the water suction pump and save water loss. 4.Flow area is 2 to 3 times of the pipe area about stainless steel or carbon steel strainer basket. Technical Specification: 1.Size Range: NPS2~NPS20,DN50~DN500 2.Applicable Temperature: 0~300 3.Connection Type: Flange or screw 4.Sealing material: soft sealing or hardness sealing 5.Material of main partsWCB,stainless steel 6.Test standardGB/T13927,API598 Application: FREE-VALVE's flange foot valve is designed for using in irrigation as well as other pumping applications where water may be dirty due to suspended silt and sand. It offers extremely low head loss. Valve body is cast steel construction. Ports are female screw or flange for easy installation.

Product Advantages: Ball valve is a new valve widely used in recent years, it has the following advantages: 1.The fluid resistance is small, and its resistance coefficient is equal to the same length of pipe section. 2.Simple structure, small size and light weight. 3.Tight and reliable, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum system. 4.Easy to operate, fast to open and close, from full open to full close as long as the rotation of 90 , easy to remote control. 5.Easy maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient. 6.When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium, which will not cause erosion of the sealing surface of the valve when the medium passes through. 7.Wide range of applications, from small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.Valves of this type shall generally be installed horizontally in pipelines.
