Product Description
The products shown here is only to present the scope of our business activities. We can manufacture no standard parts according to your drawing or sample.Sanitary Stainless Steel Butterfly Valve with Pull type handle 304/316LA butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates.A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
There are different kinds of butterfly valves, each adapted for different pressures and different usage. The zero-offset butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating. The high-performance double offset butterfly valve, used in slightly higher-pressure systems, is offset from the centre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear. The valve best suited for high-pressure systems is the triple offset butterfly valve. In this valve the disc seat contact axis is offset, which acts to virtually eliminate sliding contact between disc and seat. In the case of triple offset valves the seat is made of metal so that it can be machined such as to achieve a bubble tight shut-off when in contact with the disc.
Advantages of Stainless Steel Casting
- Sizes: 0.1 in to 24 in
- Weights: a few grams to more than 50 pounds
- Surface: very smooth finish
- Tight tolerances
- Reliable process controls and repeatability
- Design and casting versatility
- Efficient production
- Affordable tooling
- Material variety
Investment Casting vs. Die Casting
Investment casting has significantly cheaper tooling and is a more cost-effective option for lower quantity production runs. Additional benefits include a larger alloy selection and the ability to cast larger pieces.
Investment Casting vs. Sand Casting
Investment casting provides a better surface finish and allows for greater design flexibility including the ability to cast thinner walls, create tighter tolerances and create more intricate coring.
Investment Casting vs. Machining
Investment casting can significantly reduce the cost and lower the production time per piece. This is accomplished by producing near net shape parts, while greatly reducing the amount of material waste. In some instances, multiple fabricated parts can be produced as a single casting.
