Shanghai Liangzheng ValveD81X-16Q Fire Clamp Groove Handle Butterfly Valve

The D81X and D381X groove butterfly valves are suitable for pipeline systems in petroleum, food, papermaking, hydropower, ships, water supply and drainage, smelting, energy, and other industries. They can be used as regulating and throttling devices on various corrosive and non-corrosive gas, liquid, semi-fluid, and solid pipelines and containers. They are particularly widely used in high-rise building fire protection systems and other pipeline systems that require displaying the valve's open/close status.

Product Features:

1. Quick installation with groove clamp fittings and corresponding pipe components. No welding required during construction, eliminating the need for secondary galvanizing and reinstallation. Improves installation speed.

2. Lightweight clamp fittings with fewer bolts, easy to install, and no special skills required.

3. Unique C-shaped rubber sealing ring achieves triple sealing.

4. Safe installation using groove-type clamp fittings and corresponding pipe components. Only mechanical assembly is needed, with no welding or open flames, ensuring no weld slag contaminates the pipeline. Ideal for construction in fire-prohibited environments.

5. Economical due to quick installation, no special skills needed, and low rework rates. Overall installation costs are 30-50% lower compared to flanges.

6. Space-saving design: Groove-type clamp connections occupy about 70% of the space required by flanges. With fewer bolts and no directional constraints, they are especially suitable for construction in confined spaces.

7. Simple maintenance: With reliable product quality, proper installation ensures pipelines pass pressure tests on the first attempt, operate safely, and generally require no maintenance. Components do not need replacement for decades.

8. Wide applicability: Groove-type clamp fittings can connect various metal pipes, including seamless steel pipes, galvanized steel pipes, welded steel pipes, stainless steel pipes, and copper pipes.

9. Enables flexible pipeline connections: Flexible groove-type clamp fittings create a flexible system that absorbs length displacement caused by temperature changes and allows for certain angular deviations in pipes.
