Feature

Design Standard

1 Wafer & lug bodies butterfly valve for bi-directionaldead-end service are offered as standard in fullANSI Class 150 and 300 ratings.The design of Double offset sealing assure smoothlow-torque operation and reduce seat wear.Extended neck length allows adequate insulationand is easily accessible for mounting actuators.

2 Valve has a disc stopper to prevent disc over-travel of disc, minimizing possible seat damangewith extending the service life of valve operator.

3 The disc has been hydromechanically designed tomaximize flow and minimize resistance, providinga high Cv value.The disc is spherically machined and handpolished disc edge provides bubble-tight shut-offat minimum torque.

4 One piece through stem design achieves highstrength and posive disc control Optionalmounting Plate is available to internationalstandard.Non-lubricated, Coated bearings securely supportthe stem and minimize bearing friction andoperating torque.

5 Securing the butterfly disc to the valve shaft andpermitting accurate disc closure for consistentsealing and positive shut off.

6 V-Packings are designed to give excellentresistance to pressure and efective at both lowand high pressures with little of no glandadjustment required.Grafoil packings are also available for hightemperature applications and are standard on fire-safe valve & Metal Seat.

7 All valves shall be tested for leakage at ratedinternal pressure, and We can accomplish Zerodefects through a wider range testing process

8 With a locking spring loaded, lever operator hasdirectional pointer for valve disc position indicationwith easy-grip handle
