CBF01-TL01-Operation and Maintenance Manual download Extended Stem Lug & Tapped Butterfly Valve with Hand Lever Actuation Direct-Mount Isolation-1 (1)

Key Features:

1. Threaded Lug Body with Tapped Holes

Direct bolt-to-body mounting eliminates nuts, reducing installation time by 40% vs. standard lug valves.

Class 150 tapped holes prevent thread stripping during thermal cycling.

2.Extended Stem for Accessibility

stem extensions position hand lever above insulation/obstacles, compliant with ISO 5211 height standards.

sealed stem bushing prevents grit ingress in dusty/marine environments.

3. Low-Torque Hand Lever Actuation

Forged stainless steel lever (304 SS) with 4:1 mechanical advantage reduces operating force to ≤50 Nm at PN16 pressures.

4. Zero-Leakage EPDM/PTFE Sealing

Double-offset EPDM seat achieves EN 12266-1 Class A shutoff (tested at 1.1x PN16).

Optional PTFE seat for chemical resistance (-20°C to 200°C).

5. Corrosion Defense System

Body: Ductile iron with 250µm epoxy coating.

Disc:You can choose 316L stainless steel with a surface that has undergone electropolishing, which has strong corrosion resistance.
