A pneumatic actuated wafer butterfly valve is a quarter-turn flow control device that combines a compact wafer-style body with a pneumatic actuator for automated operation. The wafer design allows the valve to be sandwiched between two pipe flanges, saving space and reducing overall weight compared to flanged or lug designs. The pneumatic actuator delivers fast, reliable response–making this valve an excellent choice for automated process lines, remote-controlled systems, and applications requiring frequent cycling.
As a direct OEM/ODM manufacturer with over 19 years of export experience, Tianjin Worlds Valve Co., Ltd. delivers fully customizable pneumatic wafer butterfly valves–materials, sizes, pressure ratings, flange standards, coatings, and actuator configurations–all tailored to your exact specifications. Our products are exported to more than 50 countries and backed by ISO 9001 (certified by LRQA), CE, UKCA, WRAS, and ACS certifications.

1. Wafer Type Design–Compact & Economical
Space-Saving–The wafer body is sandwiched between two pipe flanges, requiring minimal face-to-face space and reducing overall pipeline length.
Lightweight–Up to 40% lighter than flanged or lug designs, simplifying handling and reducing structural load on piping systems.
Cost-Effective–With less material and simpler machining, wafer valves offer excellent value for general-purpose industrial applications.
2. Body Material–CI (Gray Iron)
Reliable Strength–Gray iron provides adequate mechanical strength for PN10/PN16 service in water, oil, and gas applications.
Excellent Machinability–The material allows precise casting and tight dimensional tolerances, ensuring reliable flange sealing and smooth disc operation.
Economical Choice–CI offers a cost-effective solution for general industrial service where high impact resistance is not required.
3. Disc Material–DI with Nylon Coating
Superior Wear Resistance–The nylon coating protects the ductile iron core from abrasion, extending disc life in water, wastewater, and mildly abrasive media.
Corrosion Protection–Nylon coating resists corrosion and chemical attack, making the disc suitable for a wide range of industrial fluids.
Smooth Surface–The low-friction nylon surface reduces operating torque and ensures smooth disc movement, minimizing actuator sizing requirements.
4. Pneumatic Actuator–Fast Response & Automation
Rapid Operation–Pneumatic actuators deliver fast open/close cycles, ideal for automated process control and emergency shut-off applications.
Flexible Configuration–Available in double-acting (air-to-open/air-to-close) or spring-return (fail-safe) designs to suit your safety requirements.
Accessory Integration–Easily fitted with limit switches, solenoid valves, positioners, and air filter regulators for complete automation.
Hazardous Area Ready–Pneumatic operation is inherently explosion-proof, making it suitable for ATEX or other hazardous environments.
5. ISO 5211 Top Flange–Standardized Mounting
Universal Compatibility–The ISO 5211 top flange accepts a wide range of pneumatic, electric, or hydraulic actuators without custom brackets.
Easy Upgrade–If your automation requirements change, simply swap the actuator without replacing the valve body.
Simplified Maintenance–Standardized mounting reduces downtime during actuator replacement or servicing.
Pneumatic actuated wafer butterfly valves with CI body and nylon-coated DI disc are trusted across a wide range of industries:
Water Supply & Distribution–Pump discharge, distribution mains, zone isolation.
Wastewater Treatment–Sewage lines, aeration systems, effluent discharge.
HVAC Systems–Chilled water, hot water, cooling tower circuits .
Industrial Processing–Cooling water, process fluids, chemical dosing.
Fire Protection–Fire water lines, sprinkler systems, deluge valves.
Irrigation–Agricultural pump stations, landscape irrigation.
