12 Inch Double Flanged Water Supply Gate Valve
Cast Iron Gate Valve Introduction:
Resilient seated ductile iron gate valve also commonly known as a
sluice valve. The gate valve is manually operated by a rising stem
handwheel operation made in accordance with AS2638.2. AS4087 PN16
flanged (compatable with table D/E). Great for use in waste water,
water treatment and fire industries. Outside stem and yoke,
clockwise to close. All Bolt holes are silicone filled to avoid
water pooling and corrosion. Gate valve features oversized SS431
shaft & stem, Bronze wedge nut, double shaft seals and twin lip
seals to prevent ingress and egress of media and foreign material.
This ensures the longest possible life of the valve as well as
unrivalled performance.

Cast Iron Gate Valve FEATURES
⊙ Treating with rubber
Both inner and outer are coated with advanced knowledge of rubber vulcanization then making
sure of the elasticity of rubber ,and make sure the exact geometry dimension. Rubber and ductile
cast iron valve hand together hardly. This can avoid fall-off due to long-term use.
⊙ Anti- corrosion
Both inner and outer are coated with non-toxic powder epoxy resin to strengthen the capacity of Corrosion resisting and raise the quality
of water supply.
⊙ Ruggedization
The older ductile iron valve is easy to rupture after being impacted by nonego. It can stop
rupture depend on the good mechanics capability of ductile iron .
⊙ Three “○” sealed ring
With the three “O” – rings, the leakage can be greatly reduced and the “O” – ring can be
replaced under this condition with pressure and without stopping water. The thrust axletree
reduces the frictional resistance and lowers the operational torque. And it can be switch seal
ring without opening and closing.
⊙ Rigid round body
The body is founded minutely, the rigid geometry size ensure inner sealing of valve without
any process.
⊙ Light weight
This body is made of ductile iron, it is 20%-30% lighter than the olds. Easily to fixing and
servicing.
Cast Iron Gate Valve Applications :
This valve widely applied in the liquid pipes for opening or closing fixing in such
water, sewage disposal, electric power, energetics pipe , chemical, shipping, energy sources etc.
