Description

WAFER TYPE BUTTERFLY VALVE PTFE SEAT – KTN 266IT

The KTN 266IT is our butterfly valve with a wafer type connection  and seat made of teflon (PTFE) and disc in polished stainless steel CF8M, resistant to wear and corrosion. The polished surface prevents dirt from adhering , it also gives it the property of being able to work with various media such as: wastewater, wastewater, seawater, air vapor, food, oils, medicine, alkalis, salt, etc. The range is from DN 50 to DN 300 . pressure range: PN16 . The working temperature range covers -35ºC to + 200ºC .

VÁLVULA DE BOLA BRIDAS DIN EN ACERO INOXIDABLE
Two-piece wafer structure
Epoxy coated two piece body, all bodies meet ASME Class 150 and DIN 3840 pressure ratings. The extended neck design in all valve sizes allows for 2” piping insulation and provides easy access for mounting actuators. The locating holes in the wafer version provide quick and precise alignment during valve installation eliminating disc interference with adjacent pipe.
Resilient seat design

The inner seat is machined with a curvature from the center to the edge, this unique seat geometry minimize the contact forces between the disc and seat as the disc aproaches, or opens from closed position. As a result the valve permits lower torques and reduces seat wear. FDA aproval PTFE.

Polished disc
The disc is made of CF8M polished stainless steel for is resistance to wear and corrosion. Polished surface prevents dirt from caking.
Butterfly spring disc
Two seats of spring discs imposes elastic force on the press sleeve and compacts the O ring and the seat, improving axial sealing and providing bearing stress for the seat and disc to cover elasticity shortage of the PTFE seat. This effectively prevents the media leakage from the valve cavity.
Top stem bushing
A top stem bushing is retained by a stainless steel ring, is provided to absorb actuator side thrusts and assures smooth interaction between upper shaft and lower shaft.
Seat energizer
A resilient seat energizer is extended completely around the seat, including the disc hub. This provides sufficicient uniform force for bubble tight shut off.
