Through Conduit Expanding Gate Valve Body
We are a professional manufacturer capable of producing all kinds of gate valve bodies according to our customers' specific requirements. Our Through Conduit Expanding Gate Valves combine the features of through conduit service with those of standard gate valves that have parallel seating surfaces. These valves are available in single or double expanding systems. In the case of a single expanding system, the two halves of the gate are pushed against the seats by an internal stop when the valve is closed. For a double expanding system, the same expansion occurs both when the valve is open and closed.
Technical Specification
Design and manufacturing standards: API 6D / ASME B16.34
Face-to-face standard: API 6D / ASME B16.10
Pressure-temperature rating standard: ANSI B16.34
Flange end dimension standard: ASME B16.5 / ASME B16.47
Welded ends dimension standard: ASME B16.25
Inspection and test standard: API 6D / API 598
Materials: Carbon steels, low temperature carbon steel, austenitic stainless steels, duplex and superduplex stainless steels, and nickel alloys. The reference standard is API 6D full bore.
Pressure classes typically range from 300#, 600#, 900# to 1500#, 2500#. These pressure classes meet the ANSI standard.
Sizes vary depending on the pressure class requirements.
Design Features
1. Valve position indicator: This feature allows operators to easily monitor the position of the gate during operation, indicating how much of the bore is open or closed.
2. Dust-proof design: The stem packing is installed inside the bonnet, and the outside dust is isolated by the bonnet. The packing can be easily tightened by the bonnet.
3. Stem and seat sealant injectors.
4. Zero leakage between body and bonnet.
5. Float seats: The spring-loaded seat and double O-ring seal design ensure perfect contact between the gate and seat. This design also enables the valve to have double block and bleed and pressure automatic relief functions.
6. Double block and bleed function (DBB).
7. Fire-safe design.
8. Bi-directional operation.
9. Easy maintenance without removing from the pipeline.
