Ductile Iron Cast Steel Soundproof Silent Check Valve For Water Pipeline Use
Product introduction:
Foot valve, also names bottom valve, which is a type of check valve that plays a role in preventing medium backflow during installation. Mainly used in mechanical equipment for treating slurry such as water pumps, the foot valve is usually installed at the bottom of the underwater suction pipe of the water pump to prevent slurry backflow. The bottom valve is equipped with multiple inlet ports on the valve cover and a filter screen to reduce the inflow of debris and reduce the probability of blockage of the foot valve. Although foot valves are equipped with anti clogging screens, they are generally suitable for cleaning media. foot valves are not suitable for media with high viscosity and particles.
Foot valve is an energy-saving valve that is generally installed at the bottom of the underwater suction pipe of a water pump, limiting the liquid inside the pump pipe from returning to the water source and playing a function of only entering but not exiting. There are many water inlets and reinforcing ribs on the valve cover, which prevent blockage and are mainly used in pumping pipelines. The function of waterways and supports. There are single lobe, double lobe, and multi lobe types of diameters, with flange connections and threaded connections.

Product features:
1. The structure is ideal both in terms of flow rate and process requirements, and there will be no turbulence during emptying.
2. It can provide all current international standard interfaces, such as welded, clamp, or threaded.
3. The valve body material is all US304.SUS316L, and other alloy steels can also be used according to customer requirements.
4. The surface of the valve body can be mechanically or electrically polished according to customer requirements, with an accuracy of up to 0.25um.
5. The bottom valve can be equipped manually or pneumatically. Each water pump should be equipped with one bottom valve, which is usually installed below the water surface, while the water-based bottom valve is installed above the water surface. It is an updated product of the old bottom valve, an ideal water diversion equipment, and can also replace vacuum pumps and vacuum pumping devices.
6. The bottom valve is designed reasonably, with advanced manufacturing technology and convenient installation, use, and maintenance. And it has the advantages of low friction resistance, long service life, energy conservation, etc. It is widely used as a supporting facility for water pumps in industries such as petrochemicals, chemicals, textiles, printing and dyeing, metallurgy, mining, drainage and irrigation.
