Sanitary check valves are mainly used to prevent the backflow of fluids. These valves only allow flow in one direction. In fact, they are one of the few valves that can be automated to open and close without help. Unlike other types of valves, check valves continue to operate even after the plant has lost air, electricity or manual control of the crew in operation. They are widely used in a series of processes in the health industries. Check valves are everywhere. You may have a check valve in your home, but you do not know it.
Sanitary check valves with butt-welded ends are used in the installation of pipes to prevent the reverse flow of fluids. For this reason, they are also known as check valves. The valves can be used in the pharmaceutical, chemical, beverage and food industries. This is because they were built with easy-to-clean materials and allow fluid flow from one end to the other. They can be used in pumps, cooling towers, pressure pumps, nitrogen purge lines, sump pumps and many others. The valves make it easy to maintain a high level of hygiene thanks to its corrosion resistant material. When the pressure below the valve exceeds that of the valve plug and the force of the spring, the valve opens and fluid can flow in one direction.
The valve has been designed with stainless steel material to avoid contamination by corrosion and rust. It has also been constructed with a smooth surface to allow a fluid flow of fluids. This feature is particularly important in industries that use highly viscous fluids. The valve itself is self-draining. The bottom valve has been designed to wash fluids that may get stuck in the valve. The stainless steel material is also hard enough to withstand high pressure, temperature, and volume. The seats and seals are also made of materials approved by the FDA.
