Product Description

 

Introducing a remarkable series of Zero-Leakage ball valves, expertly engineered for unparalleled performance in demanding service applications characterized by high temperature and/or high pressure conditions.
Experience the superior durability of our ball and seat, which are meticulously hard-coated with either chrome carbide or tungsten carbide, ensuring exceptional resistance to erosion and abrasion.
At SNT, we pride ourselves on utilizing the state-of-the-art HVOF coating system. Our proprietary mate-lapping technique guarantees a flawless 100% sealing, complemented by live loading to ensure zero emissions. The innovative design ensures the ball remains in constant contact with the seat, effectively wiping away contaminants. This self-cleaning mechanism prevents any interference or damage from contaminants, making this valve an ideal choice for slurry service and abrasive service applications.
