Api 600 Flanged Cast Stainless Steel Flexible Wedge Gate Valve A351 CF8 Ansi 900LB
Features:
1. Body and Bonnet Connection
Class 900LB gate valves are usually connected with bolted bonnet design.
2. Seat
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.
3. Disc Design
NPS≥2 Gate valves are flexible wedge gate.
4. Backseat Design
All gate valves have backseat design. In most cases,the carbon steel gate valve is fitted with a renewable back seat. For stainless steel gate valve, the back seat is machined directly in the bonnet or be machined after welding.
5. Stem Design
The stem is integral forged design. The minimum diameter of the stem shall be as per the standard requirement.
6 .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.
7. Operation
Hand wheel or bevel gear box is usually used for gate valve operation.
8. Bonnet Gasket Style
Ring Joint gasket is used for Class 900 gate valve;
9. Packing Seal
As usual, flexible graphite is used for packing material. PTFE or combined packing material can be also used if being requosted by the customer.
