DINKONDA GLOBAL Power Plants Special Q47F Series Pneumatic Gear Rack Actuator (double Acting/single Acting Spring Reset) Metal Sealed Floating Ball Valve

DINKONDA GLOBAL Power Plants Special Q47F Series Pneumatic Gear Rack Actuator (double Acting/single Acting Spring Reset) Metal Sealed Floating Ball Valve

Product Overview
Q47F pneumatic fixed ball valve adopts a fixed ball body, upper and lower shaft support structure, equipped with double acting pneumatic gear rack actuator, matched with solenoid valve, air filter pressure reducing valve, and valve position feedback limit switch. By driving the actuator to rotate 90 ° with compressed air, the pipeline medium can be quickly cut off or connected; The metal hard seal structure is resistant to high temperatures and erosion, suitable for high-temperature steam and media containing dust particles. It is widely used in process pipelines such as chemical, metallurgical, power plant, and gas industries.

Structural Composition
Valve body, valve cover, fixed ball, upper and lower valve shafts, metal hard seal valve seat, valve stem, packing assembly, flange connection end, pneumatic actuator, solenoid valve, air filter pressure reducing valve, valve position signal feedback device.
1. Valve body: WCB cast steel/304/316 stainless steel optional, strong rigidity, stable pressure bearing;

2. Sphere: Fixed ball structure, medium pressure borne by upper and lower supporting bearings, small opening and closing torque, suitable for large diameters;

3. Sealing pair: metal hard seal, resistant to high temperature and erosion, suitable for media containing solid particles;

4. Pneumatic actuator: gear rack type, double acting (can be reset by a single acting spring), fast action response;

5. Complete set of accessories: solenoid valve, air source triple piece, limit switch, can be connected to DCS control system, remote feedback of valve switch status.

Core Features
