Aplications
Foot valves are commonly used in ponds, swimming pools, wells and almost anywhere there is a pump.
The surface or opening of the foot valve is larger than that of the pipe, thereby minimizing pressure loss (energy dissipated due to friction along the pipe).
Our metal seated gate valves serve to stop or give complete passage to a fluid, they are bidirectional, and they open and close the circuit using a wedge with a conical design.
They have a concave housing at the bottom of the valve where sediments, impurities from the network are lodged and remain embedded in the wedge and are then released. These will be cleaned during maintenance or repair.
They are suitable for installation in those points where they must remain normally closed because, when the wedge fits into the body, they present good tightness under any circumstance and offer great durability. We will also use them when it comes to handling compressible fluids such as steam so that slow closing does not cause hydraulic phenomena that could damage the valve and the general system.
PTFE packing for excellent sealing effect and anti-corrosion properties. PTFE (Teflon®) is a very chemically resistant material with great climatic resistance, high resistance to ozone and high resistance to the degradation effects of acetones, petroleum, and tar.
They are installed in pipelines as isolation valves. Do not use them as control or regulation valves. To close we will make a rotating movement of the steering wheel clockwise and counterclockwise to open. As these are external spindle valves, operation is carried out by means of an ascending threaded spindle that rises and falls together with the wedge as the valve is operated, which provides a visual indication of the position of the valve and allows the spindle to be greased. . A spindle nut placed on the top of the wedge is fixed by pins to the spindle so that the assembly moves up and down at the same time.
They are used when a small head loss and total pitch are needed. When it’s all open, it usually does not present obstruction to the passage of the fluid, which gives a low pressure loss. As they are completely open, the design allows the use of devices to clean the interior of the pipelines. The manually operated valve being slow in operation will also prevent effects of water hammer.
