Cast Ductile Iron Flanged Foot Valve with check type structure PN10
1.Designed for long service life
Ductile iron body maintains the anti-corrosive properties of cast
iron while achieving a yield strength comparable to carbon
steel.Ductile Iron also offers higher pressure/temperature ratings
than cast iron .carbon and stainless steel units are also available
2.Minimal Head Loss
Head loss is minimized by providing a large cross-sectional area
which exceeds that of the adjacent pipeling .additionally,the
spring-loaded,canted guided disc id designed with very low carcking
pressure which reduces the amount of energy required to open the
3.Quick closure to reduce weater hammer
Silent shut-off is achived via the fully automatic.spring assisted
disc that closes near zero flow velocity.the lightweight ,center
guided disc design creates a ositive shut off prior to flow
reversal and helps to keep slamming and surges to a minimum.
4.Numerous screeen options
The standard screen construction material is type-304 stainless
steel. iddition, a wide variety perforations,meshes,and materials
are readily available.screens can be basket shaped or cone shaped.
Cast Ductile Iron Foot Valve with check type structure PN10 PN16
1. A foot valve is a special type of check valvethat has a built-in
strainer.It is installed at the intake side of a suction pipe and
pump.its popose is to pprevent the loss of prime when the liquid
source (wet well) is lower than the pump.prime is desined as the
charge of loquid required to begin pumping action and priming is
the process of fillling the pump and suction pipe with liquid.
2.The check valve part of the foot valve opens when the pump starts
to allow liquid to enter the suction pipe and pump.when the pump
stops the check valves closes and prevents the liquid from
emptying.thus the foot valve eliminates the need too prime the pump
each time it is started.the strainer component of the foot valve
helps to romove unwanted debris from the liquid that may cause
damage to the pump.
