As infrastructure grows more complex and industries demand higher efficiency and reliability, valve technology must evolve to meet these challenges. Whether in municipal water networks, industrial pipelines, or wastewater treatment systems, valves play a critical role in ensuring flow control, pressure regulation, and system safety. Among the most crucial components are double offset high performance butterfly valves, double orifices air valves, and ductile iron double eccentric butterfly valves.
These cutting-edge designs from WTS Valves combine durability, operational efficiency, and precision—making them indispensable for a wide variety of applications.
The Role of the Double Offset High Performance Butterfly Valve
The double offset high performance butterfly valve is a major advancement in valve engineering. Unlike traditional concentric butterfly valves, this model features two offsets in its design: one at the shaft axis and another at the seat plane. This geometry reduces wear on the sealing surface, enabling tighter shutoff and longer service life.
Key Features:
- Bi-directional sealing capability
- Resistant to high temperature and pressure
- Suitable for HVAC, chemical, oil & gas, and power industries
- Reduced operating torque for energy savings
Because the disc moves away from the seat during operation, friction is minimized, making the valve especially well-suited for applications requiring frequent cycling and minimal leakage.
Double Orifices Air Valve: A Small Device With a Big Job
Air valves might seem minor, but their function is essential for maintaining the health of a pipeline system. The double orifices air valve performs two vital roles: releasing air pockets during system start-up and admitting air during pipeline drainage or vacuum conditions.
Without proper air control, trapped air can cause flow disruptions, increased energy consumption, and even catastrophic pipe bursts. WTS’s design includes a large orifice for high-volume air discharge and a smaller orifice for continuous low-flow venting—ensuring the system remains balanced at all times.
Benefits:
- Prevents pipeline surges and vacuum damage
- Improves pump efficiency and flow accuracy
- Durable build for corrosive and high-pressure environments
- Automatic dual-action for different flow conditions
Ductile Iron Double Eccentric Butterfly Valve: Strength Meets Precision
In applications that demand a robust valve capable of withstanding high-pressure conditions while delivering precise control, the ductile iron double eccentric butterfly valve is the ideal choice.
Its double eccentric structure, where the shaft is offset from both the pipe center and the valve seat, provides a cam-like closing action. This allows the disc to quickly disengage from the seat with minimal wear. The ductile iron body ensures durability and resistance to mechanical stress, making this valve perfect for waterworks, fire protection, and industrial processing.
Highlights:
- ANSI and DIN standard compatibility
- High sealing integrity and low maintenance
- Resilient seat and corrosion-resistant coatings
- Long-term reliability under cyclic loads
Choosing the Right Valve for Your Application
Each valve type serves a unique purpose in flow control systems:
| Valve Type | Best For | Advantages |
|---|---|---|
| Double Offset High Performance Butterfly Valve | Industrial pipelines, HVAC, power plants | Bi-directional sealing, minimal wear, high-pressure tolerance |
| Double Orifices Air Valve | Water transmission pipelines, irrigation, wastewater systems | Prevents surges, balances air flow, enhances efficiency |
| Ductile Iron Double Eccentric Butterfly Valve | Municipal water systems, fire protection, industrial lines | Robust build, tight shutoff, extended service life |
Investing in the right valve improves system reliability, reduces downtime, and ensures compliance with safety and operational standards.
