Product Description

Technical Specifications

Valve Type:	Flange ball valve	Structure:	2PCS type
Standard:	BS5351	Workmanship:	Investment casting
Sealing Direction:	Single-directional	Sealing Grade:	Zero leakage
Temperature:	-20°C < T < 120°C	Operation:	Handle

Characteristics

The ball valve features exceptional sealing performance. The seat sealing ring is crafted from PTFE/RPTFE material, ensuring a tight fit with the ball. As medium pressure increases, the sealing force follows, providing high reliability for critical applications.

Key Advantages

Low Fluid Resistance: Ball valves offer the lowest resistance among all valve types, minimizing energy loss even in reduced diameter configurations.

Superior Sealing: Elastic valve seat materials adapt to pressure changes to maintain zero leakage.

Easy Operation: Quick 90-degree rotation allows for fast opening and closing with minimal operating torque, suitable for both manual and automated control.

Packing & Delivery

All products are secured in Standard export wooden cases to ensure safety during international transit.

Application Scenarios

This ductile iron soft seal ball valve is a cost-effective solution for low to medium pressure environments. It is widely used in:

Municipal water supply and drainage systems

HVAC (Heating, Ventilation, and Air Conditioning)

Mining and non-corrosive industrial pipelines

Frequently Asked Questions

Q: What is the manufacturing standard for this flange ball valve? A: This valve is manufactured according to the BS5351 standard, ensuring high quality and international compatibility.

Q: Can this valve handle high-temperature media? A: The working temperature range is -20°C to 120°C, making it suitable for most standard water, HVAC, and industrial fluid applications.

Q: What does "Zero Leakage" sealing grade mean? A: It means the valve achieves a complete bubble-tight seal in the designated flow direction, preventing any fluid loss when closed.

Q: What materials are available for the valve body? A: We offer multiple material options including WCB (Carbon Steel), CF8 (304 Stainless Steel), and CF8M (316 Stainless Steel).

Q: How is the valve operated? A: It is designed for manual operation using a sturdy handle, requiring only a 90-degree turn for full opening or closing.

Q: Is it suitable for corrosive fluids? A: The ductile iron version is best for non-strong corrosion working conditions. For corrosive media, we recommend choosing the CF8M stainless steel body.
