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.
