Product Description

Introducing a remarkable range of Zero-Leakage ball valves, perfectly engineered for superior performance in a diverse array of service applications. Designed to withstand extreme conditions, these valves excel even under high temperatures and high pressure environments, making them indispensable for demanding industrial needs.
Each ball and seat within our valves are fortified with robust coatings of chrome carbide or tungsten carbide. These materials are meticulously selected for their outstanding resistance to erosion and abrasion, ensuring prolonged durability and reliable performance even in the harshest conditions.
At SNT Machinery, we leverage an advanced HVOF coating system, coupled with our proprietary mate-lapping technique, to guarantee impeccable sealing and 100% zero emissions. The innovative live loading feature keeps the ball firmly seated, effortlessly wiping away contaminants. This self-cleaning mechanism not only ensures uninterrupted operation but also protects against potential interference and damage from abrasive materials. Consequently, our valves are ideally suited for both slurry and abrasive service applications, setting a new standard in reliability and efficiency.

 

Our Advantages
