Product description
Chlor-alkali Pneumatic Single-seat Regulating Valve
The regulating valve is an anti-corrosion straight single seat regulator. The inner wall of the valve body and the valve assembly that are in contact with the fluid are lined with a corrosion-resistant, aging-resistant polyfluorinated ethylene propylene using a high-pressure injection molding process, and a PTFE bellows is added to form a seal. The stroke of the spool is proportional to the seat passage, and the medium flow can be accurately adjusted in the approved stroke.
Design Feature:
1.Innovative packing design, good sealing performance, small friction, reducing maintenance strength.
2.Special top structure design avoids friction and death between the valve cage and the valve core, stable and reliable.
3.Axial pressure fixation of the valve shaft, good concentricity, very sticky,tight closure,zero-leakage.
4.Standardized components design, interchangeability, easy combined installation, reducing the cost of use.
