Product Overview
API Pressure Seal Globe Valve is an industrial globe valve designed for shut-off control in high-temperature and high-pressure steam and industrial piping systems.
Product Features
Pressure seal bonnet design allows media pressure to act directly on the sealing ring for stable sealing under high-pressure conditions.
High-strength pressure-retaining body is designed for high-temperature steam and high-pressure industrial piping systems.
Pressure seal bonnet reduces the sealing load on the bonnet joint under high-temperature and high-pressure service.
The disc is pressed axially against the seat, helping reduce uneven wear on the sealing surfaces during repeated operation.

FAQ
Q: What applications is the API Pressure Seal Globe Valve suitable for?
A: It is suitable for high-temperature and high-pressure steam systems, power plants, petrochemical facilities and other industrial piping applications.
Q: What is the difference between a pressure seal bonnet and a conventional bonnet?
A: A pressure seal bonnet uses media pressure to maintain bonnet sealing, making it more suitable for long-term operation under high-pressure conditions.
Q: Why is a pressure seal bonnet preferred for high-pressure applications?
A: As system pressure increases, the sealing ring is pressed more firmly by the media pressure, helping maintain stable bonnet sealing.
Q: Which operating options are available?
A: Handwheel, gear-operated, electric and pneumatic actuators are available based on project requirements.
Q: What inspections are completed before shipment?
A: Each valve undergoes shell strength and seat leakage testing before shipment. Material certificates, pressure test reports and related technical documents can also be provided upon request.
