Description

PTFE LINED DISC WITH FDA COMPLICANCE WAFER BUTTERFLY VALVE – KTN 266ITT

The KTN 266ITT is our butterfly valve with a wafer type connection, seat and ptfe disc . The ptfe seat and disc give the valve great resistance to corrosion . The range is from DN 40 to DN 300 , replacing the sleeve with a reducing handwheel from DN 250 , suitable for driving practically any medium. Its pressure range: PN16 . The working temperature range covers -35ºC to + 155ºC .

Features

PTFE LINED DISC WITH FDA COMPLICANCE WAFER BUTTERFLY VALVE – KTN 266ITT

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.

PFA lined disc

The disc is made of stainless steel encapsulated with a thick layer (minimum 3 mm) of pure PTFE/PFA, which increases resistance to wear and corrosion against the most acidic fluids. Compliant with FDA standard.

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.
