1. Top Flange :- The Top Flange is Drilling as per EN ISO 5211 to Accommodate direct mounting of a wide range of Gear Box & Actuators.
2. Body :- Double Flange raised Face, serrated finish Body, Drilled to meet ANSI & Various International Standards. Bidirectional Sealing as Standard in
conformance with full ASME Class 150 and Class 300 Rating.
3. Pin :- Pins are offset from the center of the stem which places them in compression rather than shear thus eliminating potential for failure. The pin are precision
fit and wedge types which provide positive mechanical attachment of disc to stem.
4. Disc Stop :- The disc Stop is a machined position stop on the body that locates the disc in the seat to achieve maximum seat and seal life. The disc stop is designed to prevent disc from rotating in the wrong direction and minimizing possible seat damage.
5. Seat Retainer :- Retains seat in the body and is supplied in the same material as the body.
6. Stem Seal :- Stem Assembly is “Live Loaded” with two Beliville Spring Washers. This ensures continuous compression of packing and sealing contact at the stem
and body. Rocker shaped gland bridge compensates for uneven adjustment of gland bolts.
7. Blow Out Proof Stem :- Retainer Circlip provides Blow Out Proof Stem.
8. Stem :- The High – Strength Stem is SS 316 or 17-4 PH Stainless Steel that Provides Maximum Strength for High Torque Application.
9. Extended Neck :- Extended Neck allows for 2″ of Pipeline Insulation and easy Access to Stem Packing Adjustment and Gear Box / Actuator Mounting.
10. Bearing :- Top and Bottom Bearings, consisting of a 316 Stainless Steel /TFE Glass Fabric Liner Bearing Surface, Securely Support the Stem.
11. Disc :- The Disc has been Engineered to Maximize Flow and Minimize resistance to provide a High Flow coefficient (Cv). The Standard Disc Material is 316
Stainless Steel.
12. Seat :- The unique Seat Design utilizes a flexible lip seal concept. When the Disc Closes, This action causes a slight deflection in the Seat, Energizing the Seat.
During this energized position, the seat has a stored energy force constantly pushing against the disc. In addition to this “Energized” force, when pressure is on the
insert side, the pressure pushes under the lip which further amplifies the sealing force between the Disc and the Seat.
13. Bi-Directional Dead End Service :- All Valves are suitable for Dead – End Eervice to Pull ANSI Pressure Rating Bi-Directionally.
14. Adjustable Stem Packing :- The Stem Packing System Features a pull down Gland with easy access to the adjusting hex head nuts without removal of the Gear Box / Actuator.
15. Double Offset Disc Design :- The Offset Disc Produces a cam-like action, Pulling the disc from the seat. This Action reduce seat wear and eliminates seat deformation when the disc is in the Open Position. The disc dose not contact the Seat when the Valve is in the Open Condition; therefore, Seat Service life is extended and torque are reduced. As the Valve Closes, the cam-like action converts the rotary motion of disc to a liner type motion effectively pushing the disc onto the seat.
