Valve Casting
Valve Casting Foundry
JC Casting is a valve castings manufacturer with its own foundry. We provide all types of valve castings. Valves are Importance Industrial System. It is the critical component of pipeline delivery systems. valves alter the passage section and direction of a given medium’s flow into another area. Its functions include cutoff, throttling, regulation, diversion, and overflow relief.
Sizes of valves produced can range anywhere from one cubic inch up to 18” long by 18” wide by 8” high. Weights can vary anywhere from 1.5 ounces to 50 lbs. All variations are produced at our foundry.
JC Casting Company’s production process, equipment, experience, and expertise are optimal for casting valves and valve-related components.
Benefits of Valve Castings
- Design flexibility:The valve castings shapes can be designed flexibly
- Wide materials selection. Castings allow you to choose from many alloys as well as have the flexibility for internal and external configurations to suit your particular needs.
- Less expensive secondary operations by choosing an optimal casting process.
- Elimination of material waste. valve castings are cast to size.
Valve Casting Process
- Sand Casting
- Lost Wax Investment Casting
- Lost Foam Casting
A green sand-molding method is used for our valve casting processes, and it typically includes these steps:
Production of a core used to create internal passages of the valve casting. This core is made of heat-activated resin-coated sand.
Mounting a pattern designed for the customer’s specific applications onto an automatic molding machine.
Using the pattern, the machine makes the mold automatically, filling chambers above and below the pattern with sand, and squeezing the sand against the pattern to form the inner geometry of the mold.
Setting the core into the mold and closing the mold to be prepared for pouring.
Pouring the molten metal into the mold and forming the valves.
Giving the mold time to cool down and removing the castings from the sand.
Types of Valve Castings
At JC foundry we focus on the following types of valve body castings and casting components:
- Check valves: Consist of two openings in the valve body; one for fluid to enter and the other for fluid to exit. These are used in a wide variety of applications.
- Gate Valve Casting
- Globe Valve Casting
- Foot valves: A form of check valve, installed at the bottom of a pump suction line inside of a wet well.
- Pressure relief valves: Safety valves used to control or limit the pressure in a fluid system.
- Valve components – Such as poppets, strainers, and washers used to regulate and control fluid flow.
- Ball valves: This valve controls the flow of liquids using a rotary ball.
Difference Between Valve Casting and Valve Forging
Valve forging and valve casting are the two primary casting methods of creating metal valves. The main difference between casting and forging is in the way the metals are shaped. While valve forging involves shaping the metal into the desired form while the metal is still solid, valve casting involves pouring liquid metal into a mold of the valve.
