Product Description

This series provides Zero-Leakage ball valves in several service applications with high temperature and/or high pressure.
The ball and seat are hard coated with chrome carbide or tungsten carbide, which has high erosion abrasion resistance.
SNT use HVOF coating system.They are mate-lapped based on our own technique to ensures 100% sealing.Live loading also ensures zero emissions.The ball never leaves the seat and wipes contaminants away. This self-cleaning action prevents the interference and damage from contaminants. Therefore, this valve is suitable for the slurry service and the abrasive service.

 

 

 

Our Advantages

SNT Ball Valves design specifications meet all kinds of internatonal standards as ASME B 16.34-2009 ASME B16.10-2000 and API 589-2009.etc., and this series of products is widely used in petrol, chemicalindustry, lightindustry, phamacy, paper-making. metallurgy.powerstation etc.

They have charactures as below,
Simple structure offers quick-disassembly
Due to periodic maintenance of all valves. our ball valves offer ease of maintenance with non-tight fit design to save the servicing time.

Advanced sealing guarantees security
Multi-layer combined sealing of stem and body can offer the double sealing via the combination of O-ring and graphite or PTFE
This design can meet TA-Luft/Shell SPE 77/312 standards.

Long service life achieves cost-effectiveness
For metal sealed ball valves, the advanced processing is used for ball and seat ring as spray welding, spraying. fusion welding etc. to ensure the hardness of HRC58-73 and binding force of 80-40MPa,meanwhile the on-off times can be more than 100 thousands and leakage class is ANSI VI.

Modular design offers convenience
The modular design of inner sealing can offer interchangeability of soft and metal seat to ensure.

Multiple connection types offer comfortable usage.
The connection type includes flanged type(RF. FF, FM, G, RJ) screw - thread type and BW type, which are international common and offer convenient usage.

Rich experience in application offer the reliability.
SNT Valve has be widely used in petroleum, chemical industry, light industry, pharmacy, paper-making, metallurgy, power station etc. We have good reputation in the market and afford the reasonable solution on basis of service conditions.
 

Structural Features

Special packing combination can meet the smission requirement of 100 ppm meanwhile reduce the friction by 20% to stem

1. The design of anti-blow out canprevent the stem from blowing out to cause damage.

2. The structure of seat ring of wave spring and dual-scraper can clean ball surface and keep sealing.

3. Dual-sealing can guarantee the leakage class by making flow not to contact spring.

4. The sealing performance of soft seat is more stable and reliable.

5. The design of draining and sweeping can prevent valve form jammed by cleaning.

6. Comply with API 607 standards with the functions of fire-proof and anti-Static.
