The WB14(E) knife gate valve from Stafsjö Valves is a bi-directional valve with full bore, designed for reliability, efficiency and durability. The valve, manufactured from robust ductile iron or stainless steel (WB14E) and equipped with advanced sealing systems, offers excellent flow characteristics and tight sealing performance. This makes the WB14(E) a versatile choice for a wide range of industrial applications.
The WB14(E) knife gate valve is designed to optimize flow with a blind spot-free design, having full-bore passage. Its seat is in level with the bore, which minimizes pressure drops and prevents media build-up during operation. This superior design ensures the valve operates smoothly, even with challenging fluids such as sludge, or biomass. The result is not only an efficient flow but also reduced maintenance and enhanced operational longevity.
At the heart of the WB14(E)’s performance is its bi-directional zero-leakage sealing capability. The valve features casted gate guides that support the blade throughout its entire motion, ensuring smoother operation and precise control. A perimeter resilient seat offers a tight seal, regardless of pressure direction. For added durability, the single-piece valve bodies up to DN 300 come with stainless steel-reinforced seats, which provide long-term reliability under demanding conditions.
From DN 350 onward, the valve incorporates a two-piece body design, maintaining its robust performance even at larger sizes. This bi-directional functionality, combined with exceptional sealing, ensures operational flexibility across various industrial applications.
The WB14(E) valve’s top works are engineered for smooth cycling and reliable shut-off, independent of the valve position. Stainless steel tie rods encapsulated within structural beams enhance the strength and alignment of the gate. This robust construction not only improves valve performance but also reduces the likelihood of operational issues over time. All automated WB14(E) valves come equipped with stainless steel gate guards, which ensure safe and efficient operation in automated systems.
Stafsjö has equipped the WB14(E) with a state-of-the-art sealing system that ensures both internal and external leak prevention. This system is crucial for plant efficiency, media containment, and personnel safety.
Key components of the sealing system include:
One of the key strengths of the WB14(E) knife gate valve is its modular design. It can be customized with different materials, actuators, and automation accessories to meet specific application requirements. Additionally, the valve’s fully lugged design makes it suitable for dead-end service, providing versatility in challenging operational environments.
The WB14(E) series also includes variations to cater to specific needs. The WB11, for example, offers a semi-lugged design for DN 50 to DN 300 sizes, while the WB12 features a square fully flanged body in DN 150 to DN 200. For applications requiring stainless steel construction, the WB14E is available as a high-performance alternative.
The WB14(E) knife gate valve is an excellent choice for industries handling fluids such as water, sludge, and biomass. Its robust construction and advanced sealing systems make it suitable for a wide range of applications, including
Stafsjö Valves’s WB14(E) knife gate valve stands out as a reliable, efficient, and versatile solution for industrial processes requiring bi-directional flow control and zero-leakage performance. Its robust design, advanced sealing system, and modular capabilities make it a valuable asset in demanding environments. Whether handling abrasive sludge, high-temperature fluids, or sensitive media, the WB14(E) delivers consistent performance and operational reliability, ensuring long-term efficiency and safety for any application.
