1. Bonnet Gasket Style
Stainless steel + flexible graphite combined gasket;
Stainless steel + flexible graphite wounded gasket;
Ring joint gasket;
2. Packing Seal
Flexible graphite is used for packing material. PTFE or combined packing material can be also used.
3. Body and Bonnet Connection
Bolted Bonnet design. (B.B)
For carbon steel gate valve, the seat is usually forged steel. The seat sealing surface is overlaying welded with hard alloy specified by the customer. For Stainless steel gate valve, the seat is integral with body, or it can be machined directly after hard alloy welded. Threaded or welded type seat is also optional for stainless steel gate valve.
5. Disc Design
NPS≥2 Gate valves are flexible wedge gate, NPS<2 Gate valves are solid wedge gate.
6. Backseat Design
All gate valves have backseat design.
7. Stem Design
The stem is integral forged design.
8. Stem Nut
Usually, the stem nut is made of ASTM A439 D2. It is also can be made of copper alloy or other materials if being requested by the customer.
Hand wheel or bevel gear box is usually used for gate valve operation, electric actuator also can be used for gate valve operation if being requested by the customers.
