Shanghai Sote Valve Co., Ltd., a trusted industrial valve manufacturer based in Shanghai, China, presents our High Performance Stainless Steel Wafer Butterfly Valve with Full Bore Design. Engineered for demanding industrial pipe applications, this valve delivers exceptional flow control efficiency and long-term reliability. Our full-bore design minimizes pressure drop while the corrosion-resistant stainless steel construction ensures durability in harsh environments. With over 15 years of specialized manufacturing expertise, we provide valves that meet rigorous operational standards across multiple industries.
Core Technical Advantages:
Zero Flow Obstruction: Full bore design maintains pipeline ID for unrestricted flow and reduced turbulence
Corrosion Resistance: 316 stainless steel body withstands chemicals, seawater, and extreme temperatures
Bidirectional Sealing: Precision-machined disc with dual-offset design ensures bubble-tight shutoff
Low Torque Operation: Optimized disc profile reduces operating torque by up to 40% vs standard designs
Multi-Application Ready: Compatible with water, steam, oils, and mild chemical media
Technical Specifications:
| Parameter | Specification |

Operational Benefits: The valve's wafer-style installation reduces flange preparation time by 60% compared to lug-type valves. Our proprietary disc-edge sealing technology extends service life by preventing particle embedment in sealing surfaces. Available with lever, gearbox, or pneumatic actuator configurations, these valves provide flexible control solutions for:
Cooling water systems in power plants
Bulk material handling in mining operations
Process piping in chemical manufacturing
HVAC distribution networks
Marine and offshore applications
Why Choose Our Butterfly Valves: Shanghai Sote Valve has supplied over 500,000 industrial valves to global customers since 2008. Our production facility features CNC machining centers with ±0.01mm precision tolerance control. Each valve undergoes 3-stage quality verification including material spectrometry, pressure testing, and operational torque measurement. With 24-month standard warranty and lifetime technical support, we ensure your piping systems operate at peak efficiency.
FAQ Section:
Q1: What is the difference between wafer and lug-style butterfly valves?
A: Wafer valves are installed between flanges using through-bolts, while lug valves have threaded inserts for direct flange mounting. Wafer designs are lighter and more cost-effective for standard applications.
Q2: Can this valve handle abrasive slurries?
A: For slurry applications, we recommend specifying PTFE-seated versions with hardened disc edges. Standard EPDM seats are suitable for non-abrasive media.
Q3: What actuation options are available?
A: Manual lever (up to DN200), gear operator (DN150+), pneumatic actuators (double-acting or spring-return), and electric actuators (optional).
Q4: Is the valve suitable for food-grade applications?
A: Yes, with FDA-compliant EPDM seats and electropolished internals upon request.
Q5: What is the lead time for DN400 valves?
A: Standard sizes ship within 15 working days; non-standard sizes require 25-30 days.
Q6: Do you provide test certificates?
A: Yes, each valve ships with material test reports and factory acceptance test certificates.
Q7: Can the valve be installed in vertical pipelines?
A: Yes, installation in any orientation is possible with proper disc positioning.
Q8: What maintenance is required?
A: Annual inspection of seat surfaces and stem lubrication is recommended for continuous service.
