6″ 1500LB Pressure-Seal Wedge Gate Valve | High-Pressure Isolation for a UAE Project
Project Overview
This case covers a 6-inch, Class 1500 pressure-seal wedge gate valve for a project in the United Arab Emirates. The valve has an ASTM A105 forged steel body and is intended for pipeline opening, closing and fluid isolation.
The pressure-seal bonnet uses internal fluid pressure to help compress the sealing element between the body and bonnet. The term “pressure seal” refers to this bonnet joint; isolation of the pipeline is achieved by the wedge engaging the valve seats. The valve is intended primarily for fully open or fully closed service.
The process medium, operating temperature, end connections and operating arrangement are defined by the approved valve data sheet and project technical documents.

Quality Control & Surface Treatment
The forgings are supplied with complete inspection reports and full material traceability. Each valve undergoes rigorous visual inspection and pressure testing before shipment. The valves in this order passed hydrostatic shell and seat sealing tests in accordance with API 598 requirements, and each unit is supplied with a documented test report.
The paint system is applied in two stages: a primer followed by a topcoat. Finished surfaces are checked for visible defects and coating quality, providing a smooth finish with good paint adhesion.
What does pressure-seal bonnet mean?
Internal fluid pressure helps compress the sealing element between the valve body and bonnet. This bonnet seal is separate from the wedge and seat arrangement that isolates the pipeline.
Does this case use a wedge or parallel-slide gate?
This case uses a flexible wedge gate. The valve series also offers parallel-slide configurations, with the final configuration defined by the approved project documents.
Can the face-to-face length be customized?
Yes. A non-standard face-to-face length can be specified and confirmed in the approved dimensional drawing.
What information is needed for a quotation?
Please provide nominal size, pressure class, body and trim materials, process medium, operating pressure and temperature, end connections, required face-to-face length, operating method and inspection requirements.
