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
