About Our Pressure Seal Globe Valves
A Pressure Seal Globe Valve combines the flow-control capability of a globe valve with a pressure seal bonnet arrangement. The globe valve mechanism uses linear movement of the disc toward or away from the seat to regulate or shut off flow.
Its pressure seal bonnet is designed so that internal system pressure contributes to the sealing force at the body-to-bonnet joint. This makes the design particularly relevant to demanding high-pressure and high-temperature industrial services.
Engineered for Critical Industrial Applications
Pressure Seal Globe Valves combine controlled linear valve operation with a pressure-assisted sealing arrangement.
Pressure Seal Bonnet
Pressure-assisted bonnet construction helps increase sealing force as internal system pressure rises.
Flow Regulation
Globe valve disc movement allows controlled adjustment of the flow passage for regulation and throttling duties.
High-Pressure Service
The pressure seal design is commonly selected for demanding pressure-containing industrial systems.
High-Temperature Applications
Suitable valve designs can be used in demanding thermal environments when correctly engineered for the service.
Reliable Shut-Off
The disc and seat arrangement provides positive flow interruption when the valve is moved toward the closed position.
Industrial Operating Options
The valve can be configured for manual or automated operation depending on the requirements of the installation.
How a Pressure Seal Globe Valve Works
The valve uses linear movement of the stem and disc to control the opening between the disc and seat. The pressure seal bonnet provides the distinctive sealing mechanism.
Valve Opening
The handwheel or actuator moves the stem upward, lifting the disc away from the seat.
Flow Regulation
Intermediate disc positions alter the flow passage, allowing the valve to regulate process flow.
Valve Closing
The stem moves the disc toward the seat until the flow passage is closed.
Pressure-Assisted Sealing
Internal pressure acts on the pressure-seal bonnet arrangement and increases sealing force at the joint.
Sealing Performance That Uses System Pressure
The defining characteristic of a pressure seal globe valve is its pressure-assisted bonnet arrangement. Unlike conventional bolted bonnet construction, the sealing mechanism is designed so that increasing internal pressure contributes to the load acting on the pressure seal.
This design approach is widely associated with demanding high-pressure and high-temperature services, particularly where pressure integrity and long-term sealing performance are critical.
Self-Energizing Seal
Internal pressure contributes to the sealing force at the body-to-bonnet joint.
Reduced Dependence on External Bolting
The pressure seal bonnet uses an internal sealing arrangement rather than relying primarily on a conventional bolted bonnet joint.
Designed for Severe Service
Pressure seal globe valves are commonly selected for critical process and high-energy piping applications.
Thermal Cycling Considerations
The pressure seal design can be advantageous in systems experiencing demanding pressure and temperature conditions.
Benefits of Pressure Seal Globe Valves
A pressure seal globe valve can provide important advantages when selected correctly for the process conditions.
Reliable Pressure Containment
Pressure-assisted bonnet sealing supports dependable pressure boundary integrity in demanding applications.
Effective Flow Regulation
The globe valve operating principle provides controlled movement of the disc for regulating process flow.
Suitable for Critical Services
Commonly considered for high-energy, high-pressure and high-temperature industrial systems.
Enhanced Sealing Under Pressure
Increasing system pressure can increase the load acting on the pressure seal arrangement.
Industrial Durability
Robust valve construction can support demanding process environments when correctly specified.
Manual or Automated Operation
Depending on the application, the valve can be operated manually or integrated with an actuator.

Pressure Seal Globe Valve FAQs
What is a Pressure Seal Globe Valve?
A Pressure Seal Globe Valve is a globe valve with a pressure-assisted bonnet sealing arrangement. It is commonly selected for demanding pressure and temperature services.
How does a pressure seal bonnet work?
Internal system pressure acts on the bonnet and contributes to the sealing force at the body-to-bonnet joint. As pressure increases, the sealing load can increase as well.
What is the main function of a globe valve?
Globe valves are primarily used for regulating, throttling and controlling fluid flow, while also providing shut-off capability.
Where are Pressure Seal Globe Valves used?
They are commonly associated with power generation, steam systems, oil and gas, refineries, petrochemical plants, chemical processing and other demanding industrial systems.
Can a Pressure Seal Globe Valve be automated?
Yes. Depending on the valve configuration and project requirements, globe valves can be operated using suitable actuators and automation systems.
How should a Pressure Seal Globe Valve be selected?
Selection should consider operating pressure, temperature, process medium, flow requirements, valve size, connection arrangement, shut-off requirements and the applicable project specifications.
