Pneumatic Grooved Butterfly Valve

The Pneumatic Grooved Butterfly Valve is a high-speed automatic pipeline control valve that combines grooved quick-connect structure with pneumatic drive technology. Designed for fast switching, frequent operation and industrial automated piping systems, this valve uses compressed air as power source to realize rapid opening and closing, which is more efficient and safer than manual and electric valves for high-frequency working conditions. With standard grooved ends, it requires no welding or flange installation, greatly shortening construction period and facilitating pipeline disassembly, maintenance and renovation. It is widely adopted in fire protection, water treatment, HVAC systems and general industrial fluid pipelines.

The valve body is manufactured from high-strength ductile iron with electrostatic epoxy powder coating, delivering excellent anti-corrosion, rust-proof and wear-resistant performance. The precisely polished stainless steel disc ensures smooth fluid flow and avoids scale accumulation and medium erosion. The high-elastic EPDM rubber liner provides reliable bidirectional zero-leakage sealing. Featuring outstanding aging resistance, pressure resistance and temperature adaptability, the sealing structure remains stable after thousands of repeated switches, fully meeting long-term continuous operation requirements of industrial pipelines.

Equipped with a high-performance pneumatic actuator, the valve achieves ultra-fast on-off action with stable and precise operation. The pneumatic drive structure features simple principle, strong explosion-proof capability and no electric spark risk, making it inherently safer than electric valves in flammable, dusty and humid environments. Users can install solenoid valves, limit switches, positioners and air filter regulators to realize automatic switching, signal feedback and proportional flow regulation. The whole pneumatic system responds sensitively with low failure rate and strong anti-interference ability, suitable for unattended automatic control stations.

Adopting advanced grooved connection technology, the valve is lightweight, compact and easy to install in narrow pipe wells, ceiling concealed pipelines and densely arranged piping areas. The standardized grooved structure ensures precise matching with conventional grooved pipe fittings, enabling quick assembly and disassembly without damaging the original pipeline. Compared with flanged valves, it saves installation space, reduces construction cost and greatly improves project efficiency. The built-in self-locking and anti-vibration structure effectively prevents disc displacement caused by water hammer and medium impact.

With standard pressure grades of PN10 and PN16 and complete diameter range from DN50 to DN300, this pneumatic grooved butterfly valve is commonly used in fire linkage systems, municipal water supply and drainage, central air-conditioning circulating water, factory process water, sewage treatment and automated industrial fluid systems. It supports frequent cyclic operation and is highly adaptable to complex working conditions.

In conclusion, the Pneumatic Grooved Butterfly Valve integrates fast grooved installation, zero-leakage sealing and high-safety pneumatic automatic control. With fast response, explosion-proof performance, low maintenance cost and long service life, it serves as an ideal automatic control solution for modern intelligent and safety-oriented pipeline engineering.
