Industrial Pressure Seal Gate Valve
Product Overview
Pressure Seal Gate Valves for Demanding Industrial Applications
A pressure seal gate valve is an isolation valve designed with a pressure seal bonnet arrangement. This construction uses internal pressure to help energise the bonnet seal.
Compared with conventional bolted bonnet construction, a pressure seal design is commonly considered for selected high-pressure and high-temperature applications.
A seal gate valve of this type is primarily intended for fully open or fully closed operation rather than continuous throttling.
The correct valve must be selected according to the operating pressure, temperature, material compatibility and pipeline design.

Confirm the final pressure-temperature rating and inspection requirements against the manufacturer's approved datasheet.
Design & Construction
Understanding Pressure Seal Gate Valve Design
The pressure seal gate valve design differs from a conventional bolted bonnet gate valve. It uses a pressure seal arrangement at the bonnet joint instead of relying solely on a conventional bolted gasketed joint.
As internal pressure increases, the design uses that pressure to help energise the bonnet sealing arrangement. This makes pressure seal construction useful for selected demanding services.
The gate mechanism itself provides pipeline isolation. When the valve is fully open, the gate is raised away from the flow passage. When closed, the gate moves toward the seating surfaces to restrict flow.
Proper selection depends on pressure class, body material, bonnet construction, end connection and the intended process medium.
Design Selection Checklist
- Pressure seal bonnet arrangement
- Operating pressure and temperature
- Pressure class and material rating
- Body and trim material
- Valve size and face-to-face dimensions
- Flanged or butt weld ends
- Manual, gear or electric operation
- Applicable inspection requirements
- Project-specific technical documentation
Working Principle
How Does a Pressure Seal Gate Valve Work?
A pressure seal gate valve combines a gate-type isolation mechanism with a pressure-energised bonnet sealing arrangement.
01
Valve Opening
The operating mechanism raises the gate away from its seating surfaces to open the flow passage.
02
Fully Open Position
With the gate raised, the pipeline has an open flow passage through the valve.
03
Valve Closing
The gate moves back toward the seats to isolate the pipeline, while the pressure seal bonnet provides its intended sealing function.
Material Selection
Material Options for Pressure Seal Gate Valves
The supplied material options include WCB, LCB, WC6, WC9, C5, C12 and CF8M. Each material has different properties and service limitations.
Carbon steel and low-temperature steel grades may be considered for compatible applications, while alloy steel grades are used in selected elevated-temperature services.
Stainless steel options such as CF8M may be selected where their corrosion resistance is appropriate for the process medium.
Always confirm the material's allowable pressure-temperature rating before finalising a valve.
Listed Material Grades
- WCB – Carbon Steel
- LCB – Low-Temperature Carbon Steel
- WC6 – Alloy Steel
- WC9 – Alloy Steel
- C5 – Alloy Steel
