Description

Guokun Casting, of Baoding Hebei is an ISO 9001-2008 registered iron and steel foundry & supplier of high quality carbon steel, cast iron and machined castings used in power, mining, railway, agricultural, tillage, truck, automobile, pump, valve, motor, pipe fittings and gear industry. Baoding Guokun has been specialized in the designing and manufacturing of various valve components for ball valve, gate valve, globe valve, butterfly valve, through conduit gate valve, knife gate valve, bellow valve, strainers and flow control components.

What is a valve disc?

The valve disc is an important movable component within a valve that controls the flow of fluid by either allowing it to pass through or block it, depending on its position; essentially, it’s the valve components that directly regulates the fluid flow by creating a seal against the valve seat when closed.

A broad line of materials is offered and fabricated in Baoding Guokun.

Steel material ranges from cast steel, forged steel to special alloy steel like Monel, Duplex. The main material of valve disc is stainless steel 304, 316, CF8 or CF8M.

Cast iron materials in GG20, GG25 or ductile iron of GGG40, GGG50, etc.

Aluminum, brass, copper and bronze valve parts can be produced in our factory.

Cast iron valve disc

Cast iron is mostly made of iron, with some carbon and a small amount of silicone. Cast iron is often used for valve discs due to its excellent wear resistance, good machniability, high strength, and relatively low cost. Ductile iron is an iron alloy made of nodular graphite, which has higher strength and toughness than gray cast iron. Baoding Guokun casting factory choose the ductile iron to produce valve plate because the ductile iron discs are low cost, low switching torque, good sealing and high wear resistance. But cast iron valve disc is only suitable for weakly corrosive fluid medium such as water, air, oil, etc. If you need corrosion resistance valve disc for acid, alkali, salt, seawater, sewage and other strong corrosive fluid meidum, please choose the stainless steel plate produced by Baoding Guokun. And we also can produce the nickel aluminum bronze valve disc by using investment casting or sand casting process.

GGG40, also known as ASTM A536 Grade 60-45-12, is a grade of nodular cast iron and has a predominantly ferritic structure. This cat iron offer good machinability, impact resistance, elongation properties, high electrical conductivity and excellent toughness.

What’s metal casting techniques for GGG40 cast iron valve disc?

Sand casting: Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages. Baoding Guokun can produce various sand cast parts in cast iron, ductile iron, gray iron, low-carbon steel, mild steel, alloy steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc
