electric cast steel gate valves and electric iron gate is belong to product of series of electric valve. Their electric actuator configuration are the same, the main price difference lies in the body itself.

this second product from casting process perspective is not the same series, the price is more expensive than cast iron cast steel. So a lot of time need to use large diameter pipe gate valve, considering the price because, will choose to cast iron gate valves.

cast iron and cast steel has the following difference:

1. Different brightness, cast steel material is shiny, dark grey cast iron, cast iron inside of gray iron and nodular cast iron and different, brighter than grey cast iron ball.

2。 Particles of different appearance. The high density of cast steel castings and generally to the naked eye can't see the particles. Grey iron and ductile iron particles can be seen. Grey iron particles.

3。 Knocking sound different. Cast steel collision sound is & other; Just throughout the &; And the voice of the cast iron will be a little bit more boring.

4。 Gas cutting. Steel surface rough, riser, gate area is large, must be removed with gas cutting. Cut continuously cast iron with gas cutting.

5。 Toughness is different. Steel toughness is close to steel, ductile cast iron.

6。 Although both have the same as the iron carbon alloy, but hesitate contains carbon, silicon, phosphorus, sulfur and the percentage of different chemical elements, crystal has different metallographic organization structure, and shows the different mechanical properties and process performance.

summary: electric cast steel gate valve mechanical properties is higher than electric cast iron gate valves, cast steel gate valve performance was worse than cast iron gate valves, cast iron gate valves is much cheaper than cast steel gate valves. as a domestic high-end valve manufacturer, always respond to national policy and called for, committed to researching, developing and manufacturing electric butterfly valve, stainless steel ball valve, discharge valve, electric gate valves, stainless steel gate, stainless steel valve, stainless steel check valve, high pressure gate valves high-quality let customer trust of good Industrial Valves, the valve to keep traditional valve product sales profits to escort for the innovation research.
