Manual PTFE Wafer Type Butterfly Valve with Lever Handle

ce

SLVCN Lever Operated PTFE Wafer Type Butterfly Valve is designed for on-off control of corrosive media – acids, alkalis, salts, oxidizing liquids, and aggressive chemicals. The PTFE seat provides exceptional chemical resistance and a low-friction sealing surface, making this valve a reliable choice for chemical, pharmaceutical, water treatment, and corrosive fluid applications.

PTFE seat – zero leakage, no swelling, long life
Unlike rubber seals, PTFE does not swell or degrade in aggressive chemical environments. The precision-machined PTFE seat delivers bubble-tight shut-off and consistent performance over years of service.

Multiple body materials for different corrosive conditions
Choose from ductile iron (GGG40/GGG50), cast iron (CI), carbon steel (WCB), or stainless steel (CF8/CF8M/CF3M). Match the valve to your specific media – from mild chemicals to highly oxidizing acids.

Lever handle – quick 90° quarter-turn operation
Instant opening or closing with a simple quarter-turn. Ideal for frequent manual operation and tight spaces. No tools required.

Wafer type design – compact and cost-saving
Fits directly between ANSI, DIN, or JIS flanges with fewer bolts – saving space, weight, and installation cost.

ISO 5211 mounting pad – ready for future automation
Designed as standard. Upgrade to worm gear, electric, or pneumatic actuator anytime – no valve replacement, no piping modification.

100% factory tested and certified
Each valve undergoes individual pressure and seat leakage testing before shipment. MTC, Certificate of Origin, and ISO9001 certification are available. OEM customization is offered for special markings, handle color, or specific materials.
