Frequently Asked Questions
The original description states that ratings of Class 900 and above use a self-sealing structure for the listed high-pressure services.
The published description identifies lighter weight and higher assembly efficiency than conventional self-sealing valve arrangements.
Petroleum, petrochemical plants and power stations are the stated applications, including high-temperature and high-pressure working conditions.
Manual, gear, pneumatic and electric options are listed. Selection should consider valve size, operating frequency, site utilities and control requirements.
Provide medium, operating conditions, end connection, actuation, quantity and project documentation for technical review.
Product Overview
This small-diameter forged steel parallel gate valve uses a threaded bonnet and pressure-seal arrangement for demanding pipeline isolation. The gate moves linearly between the seats to open or close the flow passage.
Compared with the conventional self-sealing construction described on the original page, the listed design targets lower weight and improved assembly efficiency. For ratings of Class 900 and above, the published information specifies a self-sealing structure.
Material, end connection and actuation options can be configured for petroleum, petrochemical and power-station projects within the visible specification range.
- Pressure-Seal Construction: Specified for Class 900 and above in the original description.
- Threaded Bonnet: Supports the listed assembly-efficiency advantage.
- Forged Body: Suited to the stated demanding industrial service.
