The foot valve, also known as the check valve, is a low-pressure flat valve. Its function is to ensure the one-way flow of liquid in the suction pipe, so that the pump can work normally. When the pump stops working intermittently, the liquid can not be returned to the water source box. The suction pipe is filled with liquid to facilitate the start of the pump.
The foot valve is an energy-saving valve, generally installed at the bottom end of the water pump underwater suction pipe, which restricts the liquid in the water pump pipe from returning to the water source, and functions as an inaccessible. There are many water inlets and ribs on the bonnet, which are not easy to block, and are mainly used in pumping pipelines. The role of waterways and supports. The calibers are single-lobed, double-lobed, multi-lobed, flanged and threaded.
The foot valve is welded to the bottom of the container to achieve optimum venting, cleaning and disinfection. In addition, the working medium can be well mixed according to the various process requirements in the operation process. The foot valve is as close as possible to the bottom wall of the tank to achieve a dead angle effect.
1. The structure is ideal both in terms of flow rate and process requirements, and there is no turbulence in the case of emptying.
2. Interfaces for all current international standards, such as welded, clamped or threaded.
3. The valve body materials are US304.SUS316L. Of course, other alloy steels can be used according to customer requirements.
4. The surface of the valve body can be mechanically polished or electropolished according to customer requirements, and the precision can reach 0.25um.
5. The foot valve can be equipped with manual or pneumatic. Each pump should be equipped with a foot valve. The bottom valve is usually installed below the water surface, while the water-type bottom valve is installed above the water surface. It is an updated product of the old-style bottom valve. It is an ideal water diversion equipment and can also replace vacuum pumps and vacuuming devices.
