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, pipelines industriels, or wastewater treatment systems, valves play a critical role in ensuring flow control, régulation de pression, and system safety. Among the most crucial components aredouble offset high performance butterfly valves, double orifices air valves, et 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
Le vanne papillon haute performance à double excentrationis 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.
Caractéristiques clés:
Bi-directional sealing capability
Resistant to high temperature and pressure
Suitable for HVAC, chimique, huile & gaz, 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. Le double orifices air valveperforms 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.
Avantages:
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
Vanne papillon excentrique double en fonte ductile: Strength Meets Precision
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:
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.

Les vannes de papillon sont des composants clés dans de nombreux secteurs comme le traitement de l'eau, Systèmes CVC, et traitement chimique. Ils sont caractérisés pour leur structure non ponctuelle, petite taille, et fonctionnalité d'arrêt rapide. Néanmoins, the process of selecting the appropriate butterfly valve type plays a critical role in the system’s effectiveness, sécurité, et durabilité. Dans ce guide, we will specify three types, namely U Type Butterfly Valve, Extension Stem Butterfly Valve, and PN16 Butterfly Valve, and discuss the applications of each.
1. U Type Valve papillon
Le U Type Valve papillonis a popular choice in industrial applications that require a tight shut-off and reliable performance. It features a U-shaped body design, offering high strength and durability, making it suitable for handling water, gaz, and chemical pipelines.
Key features:
High sealing performance
Corrosion-resistant materials
Lightweight and compact design
Simple installation and maintenance
This type of butterfly valve is ideal for industries like water treatment, traitement chimique, et systèmes CVC, where reliable flow control and space-saving solutions are important.
2. Extension Stem Butterfly Valve
For applications where valves need to be operated from a distance or in deep underground installations, le Extension Stem Butterfly Valveis the perfect choice. It comes with an extended stem that allows easy manual or automated operation, even in hard-to-reach places.
Key features:
Customizable stem length
Suitable for buried or elevated pipeline systems
Compatible with manual, électrique, or pneumatic actuators
Available in various pressure ratings and sizes
This valve is commonly used in water distribution, fire protection systems, and industrial piping networks that require remote valve operation for safety and convenience.
3. PN16 Butterfly Valve
When working with higher-pressure systems, le PN16 Butterfly Valveoffers the strength and reliability required. “PN16” indicates that the valve can handle a nominal pressure of 16 bar, making it suitable for medium to high-pressure pipelines.
Key features:
Double eccentric design for reduced wear and tight sealing
Worm gear operation for precise flow control
High-performance sealing suitable for water, huile, et du gaz
Durable ductile iron construction
This type of butterfly valve is widely used in industries like oil and gas, la production d'énergie, and large-scale water supply projects, where maintaining pressure integrity is critical.
Conclusion
Selecting the right butterfly valve depends on the application, pressure requirements, and installation environment.
