Product Description

Discover the ultimate in reliability and innovation with our High Temperature Control Valves and Ball Valves designed for Heavy Duty Use. This state-of-the-art series guarantees unrivaled Zero-Leakage performance, tailored specifically for demanding service applications characterized by extreme temperatures and high pressure conditions.
Craftsmanship meets durability with our advanced ball and seat construction, meticulously hard-coated using superior chrome carbide or tungsten carbide. These materials are renowned for their exceptional erosion and abrasion resistance, ensuring longevity and robust performance across diverse environments.
At SNT Machinery (Qingdao) Co., Ltd., we utilize the cutting-edge HVOF coating system. Our proprietary mate-lapping technique ensures impeccable 100% sealing. Additionally, our innovative live loading design guarantees zero emissions. The ball remains in constant contact with the seat, effectively wiping away contaminants through a self-cleaning action. This feature makes our valves ideal for slurry and abrasive service applications, as it prevents damage and interference from harmful particles.

 

Our Advantages

Structural Features

Our special packing combination is engineered to meet the transmission requirement of 100 ppm, while simultaneously reducing friction by 20% against the stem, ensuring optimal performance and longevity.

1. The innovative anti-blowout design prevents the stem from blowing out, thereby averting potential damage and enhancing safety.

2. The expertly designed structure of the seat ring, featuring a wave spring and dual-scraper, actively cleans the ball surface and maintains a robust seal for superior operation.

3. Our dual-sealing mechanism guarantees exceptional leakage class, ensuring that the flow does not come into contact with the spring, thereby maintaining excellent integrity.

4. The sealing performance of our soft seat is remarkably stable and reliable, offering consistent and dependable service.

5. Our advanced design features draining and sweeping capabilities that effectively prevent the valve from jamming, keeping it clean and operational.

6. Fully compliant with API 607 standards, our valves provide exceptional fire-proof and anti-static functions, ensuring your safety and peace of mind.
