Product Standards

Installation and maintenance for long diaphragm life.

Valve InspectionClean the valve seat and remove debris or sharp burrs before installing the diaphragm
Bolt TighteningTighten bonnet bolts gradually in a star pattern to distribute pressure and prevent edge leaks
Air QualityUse dry, oil-free compressed air to reduce chemical degradation of the synthetic rubber
Pressure ControlKeep pressure within 0.2–0.7 MPa; exceeding 87 psi shortens diaphragm fatigue life
Temperature ControlKeep service temperature below 80°C to prevent premature diaphragm damage
Maintenance ResultCorrect installation restores rapid pulsing, reliable closure, and efficient baghouse cleaning
