④ Double seal
design(bellows+packing)
⑤ Sealing surface overlay welding
alloy layer
Roughness ≤0.5um
⑥ German coated sand casting
Surface finish:
12.5~25 microns
Conical seal:The sealing surface has self-cleaning function and is not easy to adhere to impurities, which can achieve linear sealing.
Balanced disc seal:Small disc relieves pressure and drives large disc to open easily.
Flat soft seal:The surface of the soft seal can prevent the sparks when opening and closing,it's suitable for gas media and corrosion resistance conditions.
