Reliable Flow Control for Water & Sewage Infrastructure
Water works butterfly valves are essential components in public water supply, sewage, and marine water systems, where reliability, durability, and ease of operation are critical. SW Valve's water works butterfly valves are specifically engineered for heavy-duty operation in large-diameter pipelines, supporting stable performance in drinking water, wastewater, and seawater environments.
Product Overview
SW Valve's water works butterfly valves are designed to meet international waterworks standards while ensuring long service life and safe operation under demanding conditions.
- Size Range: DN50 to DN2400 (4 inch to 96 inch)
- Coating: Epoxy painting with internal rubber lining
- Body & Disc Material: Cast iron
- Seat Materials: EPDM, NBR, FPM
- Stem Material: Stainless steel
Pressure Performance
The valve is engineered to perform reliably across a wide range of diameters and operating pressures:
- Up to 25 bar for DN80 ~ DN600
- Up to 16 bar for DN650 ~ DN1000
- Up to 10 bar for DN1200 ~ DN4000
This pressure zoning ensures structural safety and sealing reliability even in large-scale municipal pipelines.
Connection Standards
SW Valve's water works butterfly valves are compatible with a wide range of global flange standards, allowing easy integration into existing infrastructure:
- BS 4504 PN10 / PN16
- DIN 2501 PN10 / PN16
- ANSI B16.1 Class 125LB
- ANSI B16.5 Class 150LB
- MSS SP-44 Class 150LB
- AWWA C207 Class D & E
- ISO 2531 PN10 / PN16
- KS / JIS 10K, 16K, 20K
This extensive compatibility is especially valuable for public infrastructure projects and retrofit work.
Applications
SW Valve's water works butterfly valves are widely used in:
- Municipal water supply systems
- Sewage and wastewater treatment plants
- Drinking water distribution networks
- Seawater intake and discharge systems
- Industrial water pipelines
The valve is designed for smooth operation even under heavy loads and frequent cycling conditions.
Actuation Options
To support various operational environments, SW Valve offers multiple actuation options:
- Manual lever operator
- Manual gear operator
- Pneumatic actuator
- Hydraulic actuator
- Electric motor actuator
This flexibility allows the valve to be used in both manual field operation and automated water management systems.
Engineering Strength of SW Valve Water Works Butterfly Valves
SW Valve focuses on long-term durability and operational safety for water infrastructure projects.
- Thick epoxy coating and rubber lining for corrosion protection
- Stable seat design for consistent sealing in low-pressure systems
- Robust cast iron body suitable for buried and exposed installations
- Stainless steel stem for corrosion resistance and mechanical strength
- Low operating torque for easy operation, even at large diameters
These features reduce maintenance frequency and extend service life in public utility environments.
How SW Valve Differs from Typical Chinese Manufacturers
Although many Chinese manufacturers offer low-cost water works butterfly valves, significant differences exist in quality consistency and lifecycle performance.
- Coating Quality: SW Valve applies controlled epoxy thickness and curing processes to prevent peeling and corrosion.
- Material Consistency: Verified cast iron quality and stainless steel stems ensure predictable strength and durability.
- Sealing Reliability: Precisely fitted rubber seats reduce leakage and deformation over time.
- Dimensional Accuracy: Accurate machining ensures proper flange alignment and easier installation.
- Standards Compliance: Full alignment with AWWA, ANSI, DIN, JIS, and ISO standards with documented testing.
- Operational Longevity: Designed for long-term municipal use, not short-term cost savings.
- Technical Communication: Clear English documentation and responsive support for international buyers.
For American buyers and public utilities, these differences translate into lower maintenance costs, reduced leakage risk, and higher system reliability.
Conclusion
SW Valve's water works butterfly valves are engineered for the realities of water and sewage infrastructure-large diameters, frequent operation, and long service life. Through robust materials, corrosion-resistant coatings, and global standard compatibility, SW Valve delivers dependable solutions for municipal and industrial water systems.
Compared to many low-cost alternatives, SW Valve offers American and global buyers long-term value, operational stability, and confidence-making it a trusted partner for critical water infrastructure projects.
