Functions of Cast Stainless Steel Valve Body

Cast Stainless Steel Valve body is the main structure of the valve, with following key functions:

As an outer shell of the valve, precisely positions the other parts which will be installed on it, such as vale stem, valve disc, valve seat, ensuring precise opening and closing of the valve.
Sealing. Valve body is in direct contact with the flowing medium, it works together with other parts (gaskets, bonnets, pipes, etc.), keeps the valve good sealing performance even in high pressure or high temperature.
As a fluid channel. The specific designed channels inside of the valve body can control volume, direction and distribution of liquid flow, and achieve functions such as connection, disconnection, throttling or diversion.
Connection. Flanges on the valve body provides fix structure for vale and pipeline.

Production Defects and Prevention Measures of Cast Stainless Steel Valve Body

Investment casting involves many complex processes, it's easy to cause defects if any process without good control, thus may lower the performance and reduce service life of the valve.

After decades of experience manufacturing cast stainless steel valve body, Shata has rich experience in defects identification and prevention:

Defects	Reasons	Prevention Measures
Porosities	Uneven cooling during solidification process	Optimization design
		Pouring temperature control
		Cooling Speed Control
		Add chill irons
		Add ceramic cores
		Special way as company secret
Cracks	Excessive stress during casting, cooling or heat treatment	Accurate control of production parameters
Cracks	Wrong material used	Apply correct heat treatment with different materials
Inclusion	Impure molten steel	Control purity of molten steel
	Impure molten steel	Control smelting parameters to ensure fully deoxidizes
	Insufficient mold cleaning	Clean mold and pouring system thoroughly before casting
Sand Sticking	Improper mold shell treatment	Use high temperature resistant materials and strictly control the viscosity, density and mixing ratio of the coating
	Improper mold shell treatment	Ensure mold shell evenly coated with sand
	High pouring temperature	Adjust pouring temperature
	Fast pouring speed	Adjust pouring speed
Air Holes	Poor permeability of mold shell	Reasonably design the number of layers according to size and weight of valve body
	Too much gas in molten steel	Extend smelting time
	Too much gas in molten steel	Control smelting temperature
Shrinkage Holes	Unreasonable gating system	Optimize the size and position of riser with efficient compensation
	Unreasonable solidification sequence due to uneven thickness	Change to uniform wall thickness (if allowed by customer)
		Directional cooling and cooling speed control
	Improper pouring temperature	Adjust pouring temperature
