HTSW Bellows control valve
HTSW bellows sealed single-seat control valve belongs to CV3000 series control valve products.
The spool adopts an up-directed single-seat plunger type structure and the upper valve cover adopts a bellows sealed structure to prevent the media in the pipeline from leaking out from the stem and packing seal. Bellows are made of high quality stainless steel, corrosion-proof and long service life. The packing will be aging and wear phenomenon with the use of time, and the bellows formed a double seal, reliability greatly improved. The valve body flow channel is S-shaped, small flow resistance, large flow. Especially suitable for strong corrosive, toxic, radioactive media. Assembled with ZHA multi-spring film actuator, compact structure, large output force.
Product Features
1,Single seat plunger type spool, small leakage, small allowable pressure difference.
2,The control mechanism can be equipped with a straight stroke electric actuator to form a single seat electric bellows seal control valve.
3,Bellows and packing double seal, effectively prevent media leakage.
