Product Description

Key Features

Maximum Safety & Leak Prevention

Double-Block-and-Bleed (DBB), Emergency Sealing Device, Anti-Static, Fire-Safe (API 607 / API 6FA), and Blow-Out Proof Stem ensure safe operation under extreme high-pressure and flammable conditions.

Reliable Seat Sealing

Advanced seat sealing structure provides leak-free performance under high pressure, supporting both single and double sealing designs for additional safety.

Extreme Pressure & Temperature

Trunnion-mounted forged design ensures stable operation under pressures up to Class 2500 / 6000 PSI and temperatures from -196°C to 450°C.

Durable & Corrosion-Resistant

Constructed from high-quality forged steel and corrosion-resistant alloys, capable of withstanding sulfide stress cracking and harsh industrial environments.

Flexible & Easy Integration

Supports manual, worm gear, electric, or pneumatic actuation. Optional ISO 5211 direct mounting and stem extensions enable seamless installation.

Versatile Port Options

Available in Full Bore or Reduced Bore designs to optimize system flow and reduce pressure drop according to process requirements.

Frequently Asked Questions

What does Double-Block-and-Bleed (DBB) mean?

DBB refers to a valve configuration with two separate seating surfaces that isolate the valve cavity from both upstream and downstream pressure when closed. A bleed port is used to vent or monitor the cavity, which is critical for maintenance safety and preventing leaks.

What pressure and temperature ranges can these valves handle?

These trunnion-mounted forged ball valves are designed for pressures up to Class 2500 / 6000 PSI and temperatures ranging from -196°C to 450°C, depending on the material selected, making them suitable for cryogenic and high-heat environments.

What actuation options are available?

We support a wide range of actuation including manual handles, worm gears, electric actuators, and pneumatic actuators. Optional ISO 5211 direct mounting pads allow for seamless automated integration.

Which materials are best for corrosive environments?

For highly corrosive environments involving H₂S or chlorides, materials like Inconel 625, Hastelloy C, or duplex stainless steels (F51/F53) are recommended due to their superior resistance to sulfide stress cracking.

What is the difference between Full Bore and Reduced Bore?

A Full Bore valve has an internal diameter equal to the pipe, allowing unrestricted flow and pigging capability. A Reduced Bore valve has a smaller diameter, resulting in a slight pressure drop but offering a more compact and cost-effective design.

Which industries commonly use these valves?

These valves are Fire-Safe certified (API 607/6FA) and widely used in Oil & Gas, Chemical & Petrochemical, Power Generation, Offshore, Aerospace, and Water Treatment industries for critical high-pressure service.
