Características de la válvula de compuerta de cierre a presión
Advanced Seat Design
The Through Conduit Gate Valve features an advanced seat design that provides a tight seal both upstream and downstream. The seat is designed to be in full contact with the gate whether the valve is open or closed, which minimizes wear and extends the valve’s lifespan. This design also helps prevent leaks, making the valve reliable for critical applications where a secure seal is essential.
Sealant Injection System
This system allows for emergency sealing if the primary seal is compromised. By injecting a sealant, operators can quickly restore the valve’s sealing capability, allowing a continuous operation even in challenging conditions. This feature adds a layer of safety and reliability, particularly in high-stakes environments.
Block and Bleed Capability
This feature allows the valve to completely isolate the downstream side of the valve, even under full pressure. It also enables the bleeding of the valve cavity to check for leaks or to safely depressurize the valve. This capability is crucial for maintaining safety and operational efficiency in complex systems.
Ventajas de la válvula de compuerta de cierre a presión
Seguridad reforzada
The advanced features of the Through Conduit Gate Valve, such as the block and bleed capability, significantly enhance safety. By allowing the isolation of valve sections and the ability to safely release pressure, the valve reduces the risk of accidents. This is particularly beneficial in environments where safety is a top priority.
Rendimiento fiable
NTVAL’s Through Conduit Gate Valves provide reliable performance under various conditions. The advanced seat design and sealant injection system ensure valve integrity, even with wear, damage, or harsh environments, reducing downtime and maintenance for smooth, efficient operations.
Durabilidad a largo plazo
The materials and design features of the Through Conduit Gate Valve contribute to its long-term durability. A sturdy seat design and an effective sealant injection system allow these valves to be built to last. This durability means fewer replacements and repairs, providing a cost-effective solution over the lifespan of the valve.
