YHCF Pneumatic Lining Plastic Single Seat Control Valve - Regulating valve

Product Characteristics

Corrosion resistance, which can resist almost all media (in- cluding concentrated nitric acid)

Make sure there is no leakage. Double sealing with bellows and packing, good sealing performance

Make sure there is no internal leakage. The valve core and
valve seat are soft sealed, so the leakage rate is low, and the leakage level reaches Class VI
