Inspection and Test: API 598, API 600 or API 6D.

End flange dimension: ASME B16.5 (for NPS≤24)

BW end dimension: ASME B16.25.

Face to face and end to end: ASME B16.10.

Features:

1. Bonnet Gasket Style

Pressurized seal design is used for Class 2500 gate valve.

2. 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.

3. Body and Bonnet Connection

Class 2500 gate valves usually adopt pressure seal bonnet design

4. 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.

5. Disc Design
NPS≥2 Gate valves are flexible wedge gate.

6. 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.

7. Stem Design

The stem is integral forged design. The minimum diameter of the stem shall be as per the standard requirement.

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.

9. Operation
