Lugged High Performance Butterfly Valves, 316 Body, Worm Gear Operator


APPLICATION:

Adamant Valves is a professional manufacturer of soft seat, metal seat and fire-safe high performance butterfly valves, our valves are with double offset design, reach bi-directional bubble tight shutoff (zero leakage) by the use of a patented seat. Our High Performance Butterfly Valves are designed for critical applications in food and beverage processing, chemical industries, petrochemical industries, power plants, district heating. They provide exceptionally long and trouble-free service life, reducing total cost of ownership. Adamant valves are rigorously tested to meet demanding industry performance requirements. High Performance Butterfly Valves are designed for shutoff and throttling control of liquids and gas. The dynamic PTFE/RTFE seat provides bubble-tight shutoff in both directions.  The unique disc design provides lower torque and longer cycle life.

PRODUCT FEATURES:

PRODUCT FEATURES:

Lugged type butterfly valve with double eccentric design
Suitable as end of line valve up to nominal pressure
Replaceable, resilient carbon fibre reinforced RTFE seat
Operators: hand lever, worm gear operators, electric or pneumatic actuators
Face to face dimensions acc. to EN 558-1 series 20 (DIN 3202/K1)
Tight shut-off design
Excellent corrosion resistance
ISO 5211 mounting pad, permits direct mount actuation for both manual (lever and gear), pneumatic and electric actuators
Double offset configuration with conical angled disc design. Maximize flow and minimize resistance providing high Cv.
Seat available in either PTFE/RTFE or Metal. Both soft seats and Metal seats are interchageable.
Internal travel stop design to prevent over travel of the disc, minimizing possible seat damage
The heavy duty handle and 10 position notch plates allow for positioning the valve disc to precise angle stops
