Design Feature:

Body and Bonnet Connection
The body and bonnet of Class 150~Class 900 gate valves are usually bolted bonnet design. And Class 1500~Class 2500 gate valves are usually of pressurized seal design.

Gasket of Cover Flange
Carbon steel or stainless steel+flexible graphite combined gasket is used for Class 150 gate valve; Stainless steel+flexible graphite wounded gasket is used for Class 300 gate valve; Stainless steel+flexible graphite wounded gasket is used for Class 600 gate valve, and ring joint gasket is also optional for Class 600 gate valve; Ring Joint gasket is used for Class 900 gate valve; Pressurized seal design is used for Class 1500~Class 2500 gate valve.

Actuation
Hand wheel or gear box is usually used for gate valve actuation. Chain wheel and electric actuator can be also used for gate valve actuatuo if being requested by the customers.


Seat
For carbon steel gate valve, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. Welded seat is used for NPS<10 gate valves, and welded on seat can be also optional if being requested by the customer. Welded on seat is used for NPS<10 carbon steel gate valves. For Stainless steel gate valve, intergral seat is usually adopted, or to weld hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel gate valve if being requested by the customer.

Stem Design
The stem is of integral forged design. The minimum diameter of the stem shall per the standard requirement. The connection of the stem and disc is T type. The strength of the connecting area is bigger than that of the T threaded part of the stem. The strength test if that area conforms to API 591.
