JC’s Bronze Valve Series

Bronze gate valve
- Advantages: Simple structure. Low fluid resistance. Suitable for frequent operation.
- Applicable scenarios: Commonly used for cutting off or connecting media such as water, steam, and oil. Suitable for large-diameter pipelines.
- Features: Small opening and closing torque. Low flow resistance. But the height is large, not suitable for regulating flow.
Bronze ball valve
- Advantages: Quick opening and closing. Good sealing. Extremely small fluid resistance. Easy to operate.
- Applicable scenarios: Suitable for pipelines such as water, gas, and oil that need to be quickly cut off or connected. Especially suitable for high-pressure or high-temperature media.
- Features: Compact structure. Can be sealed in both directions. But not suitable for regulating flow.
Bronze stop valve
- Advantages: Good sealing performance. Accurate flow regulation. Easy maintenance.
- Applicable scenarios: Suitable for media such as water, steam, and oil that need to adjust flow or high pressure.
- Features: Large flow resistance. Large opening and closing torque. But the sealing surface wear is small.
Bronze check valve
- Advantages: Automatically prevent medium backflow. No manual operation required. Simple structure.
- Applicable scenarios: used in pump outlets, compressor pipelines and other places where it is necessary to prevent the backflow of the medium.
- Features: One-way flow. Pay attention to the flow direction of the medium during installation. Not suitable for media containing solid particles.
Bronze angle valve
- Advantages: Compact structure. Small space occupation. Can change the flow direction of the medium.
- Applicable scenarios: Suitable for pipeline corners or places with limited space. Commonly used in water heaters, heating systems, etc.
- Features: Has the adjustment function of the stop valve. But the flow resistance is large.
Advantages of JC production process
Precision casting process (investment casting)
Process flow:
1.Mold making: Use aluminum alloy mold to make wax mold
2.Wax mold assembly: Assemble multiple wax molds into a wax mold tree
3.Shell making process:
– Dip coating special silica sol slurry
– Spread zircon sand/mullite sand
– Repeat 3-4 times to form a 5-8mm thick shell mold
4.Dewaxing: 160-180℃ steam dewaxing to obtain a complete shell
5.Baking: 850-1100℃ high temperature baking for 2-4 hours
6.Pouring: 1500-1550℃ copper alloy molten liquid pouring
7.Post-processing: shell vibration, cutting, shot blasting, machining
Technical advantages:
- Dimensional accuracy can reach CT4-6 level (GB/T6414)
- Surface roughness Ra3.2-6.3μm
- Minimum wall thickness can reach 1.5mm
- Complex inner cavity structure can be cast
- Material utilization rate is more than 90%
Precision casting bronze valve casting features:
- High surface finish
- High dimensional accuracy (up to CT4-6)
- Suitable for valves with complex structures
- Reduce subsequent processing
Sand casting process
Process flow:
1.Mold preparation: metal mold
2.Molding and core making:
– Use furan resin sand for molding
– Sand mold hardness can reach 85-90 (B-type hardness tester)
3. Box assembly and pouring:
– 1450-1500℃ copper alloy pouring
– Equipped with a special pouring system
4. Cooling and unpacking: natural cooling for 4-8 hours
5. Cleaning and processing: shot blasting, grinding, machining
Technical features:
- Wide range of single piece weight (0.5kg-200kg)
- Mold life up to 5000-10000 times
- Short production cycle (first piece can be completed in 3-5 days)
- Suitable for variable batch production (1-10000 pieces)
- Cost is 30-50% lower than precision casting
Sand casting bronze valve casting features:
- Suitable for large and medium-sized valve production
- Low mold cost
- Short production cycle
- Suitable for batch orders
