The ZJHM Pneumatic Diaphragm Sleeve Control Valve is a high-performance, large-capacity control valve featuring sleeve guidance. Its large guidance area ensures excellent stability, enabling rapid in-line replacement of internal valve components for efficient maintenance that saves labor and time. Widely adopted for its stability and straightforward maintenance, this pneumatic diaphragm sleeve control valve incorporates a pressure-balanced plug design. This eliminates most static unbalanced forces on the valve disc while providing damping effects to reduce fluid-induced vibration. It is particularly suitable for applications requiring low leakage rates and operating under significant pressure differentials across the valve.
