Versatile Two Way Flow Pneumatic Turbo Welded Ball Valve for Industrial

Highlight: Turbo welded ball valve

Product introduction:

Full welded ball valve, which are widely used in underground pipelines of city gas, central heating, natural gas pipeline and pressure regulating station.Over the past 30 years,through continuous research and innovation, and the improvement of product quality.It has won the trust and praise from over30 countries.

Full welded ball valve, due to the overall structure of the valve adopts the structure of full welding process,to make the valve inside and outside of the seal has been greatly improved, because the valve for pipe or A105 forging, make the body itself did absolutely zero sand holes, there will be no body leakage, etc., not only reduce the cost of the project construction, also save time.

Product technical parameters:

Product features:

1. Fully welded structure: The valve body is fully welded to eliminate external leakage, with a compact design for convenient

installation.

2. Low torque operation: Self-lubricating PTFE metal bushing reduces friction, enabling effortless operation.

3. Double block and bleed (DBB): When closed under pressure from both sides, medium in the valve cavity can be

discharged through the blowdown valve.

4. Dual piston effect sealing: Both valve seats are sealed by pressure. In case of upstream seat leakage, downstream

pressure automatically compensates to ensure sealing.

5. Reliable sealing design: Floating seat combined with spring preload and pressure assistance achieves bidirectional

sealing. The composite sealing structure features a primary seal to prevent particle damage and a secondary rubber seal

for zero leakage, with optional polymer seals embedded as needed.

6. Emergency grease injection protection: Pressurized grease injection system addresses sealing surface leakage, while a

bottom check valve prevents medium seepage.
