Pneumatic Globe valve adopts the double-acting cylinder, the use of upper air intake cavity or inferior vena intake to remote control valve, easy to operate, flexible. Cylinder using medium: compressed air,. Pneumatic valve has simple structure, convenient maintenance; Working stroke is small, open shutoff time is short; Pneumatic cut-off valve disc and seat sealing surface USES the taper sealing, close the small friction, scouring resistance, reliable sealing. Pneumatic cut-off valve seat can be for replacement type seat, can be arbitrary combination and shut down a pair of sealing surface material, in order to satisfy the requirement condition, prolong service life.
Main structure features :
Disc and seat sealing surface using iron base alloy or department too vertical (Stellite) cobalt-based hard alloy surfacing and become, wear-resisting, high temperature resistance, good corrosion resistance, abrasion resistance, long service life.
Pneumatic cut-off valve stem through surface nitriding treatment and conditioning, with good corrosion resistance and abrasion resistance.
Can be used in a variety of pipe flange and flange seal face type, can meet the needs of all kinds of engineering and the user requirements.
Pneumatic cut-off valve body materials, variety complete, packing and gasket can be reasonable selection according to actual working condition or the user requirements, can be applicable to all kinds of pressure, temperature and medium conditions.
Pour sealing adopts screw connection seal seat or ontology austenitic stainless steel welding and become, reliable sealing, can change the packing without downtime, convenient and quick, do not affect system to run the valve adopts double-acting cylinder, use the upper air intake cavity or inferior vena intake to remote control valve, easy to operate, flexible. Cylinder using medium: compressed air,. Simple structure, convenient manufacture and maintenance; Working stroke is small, opening and closing time is short; Closed (disc) and valve seat sealing surface USES the taper sealing, closing force is small, scouring resistance, reliable sealing. Seat, seat for replacement type can be any combination and shut down a pair of sealing surface material, in order to satisfy the requirement condition, prolong service life.
