Pneumatic Bellow Seal Cage Guided Control Valve

Product Information

The valve core of the pneumatic bellow seal cage guided control valve adopts the pressure balance structure. The control valve adopts the cage guided core, and the pressure balance valve core is suitable for occasions with large pressure difference. The upper high-pressure ring is replaced with a balanced sealing ring, and the traditional double-seat sleeve valve structure is changed to a single-seat sleeve structure. 

These improvements further increase the leakage levels of sleeve regulators. The use of corrugated tube and packing double-sealed bonnet eliminates the possibility of medium leakage. This pneumatic bellow seal cage guided control valve is suitable for flow and pressure control of toxic or precious media. The opening and closing force is small, and the working condition of high pressure difference can be controlled by a small actuator thrust. The sealing performance is good, and the allowable pressure difference is large.
