Product Description

Key Features

Trunnion Mounted Ball Structure

Upper and lower trunnion bearings support the ball, preventing displacement under extreme pressure and ensuring stable operation.

Double Block and Bleed (DBB)

Dual seats provide full upstream and downstream isolation, while the cavity can be safely vented to meet high safety requirements.

Metal-to-Metal Sealing

Metal seated design withstands high temperature, high pressure, abrasive, and erosive media with stable sealing performance.

Electric Worm Gear Actuator

High output torque and smooth operation for reliable remote control, with manual override for emergency use.

Frequently Asked Questions

What is a trunnion mounted ball valve and how does it differ?

A trunnion mounted ball valve uses upper and lower trunnion bearings to mechanically anchor the ball in place, preventing it from moving under pressure. Unlike floating ball valves where the ball shifts to create a seal, trunnion mounted designs are ideal for high-pressure and large-diameter applications, offering lower operating torque and more stable performance.

What does Double Block and Bleed (DBB) mean in a ball valve?

Double Block and Bleed (DBB) refers to a valve configuration where two independent seating surfaces simultaneously block flow from both upstream and downstream sides while the trapped cavity pressure between them can be safely bled or vented. This design is critical for pipeline isolation and maintenance safety.

In what applications is metal-to-metal sealing preferred?

Metal-to-metal sealing is preferred in high-temperature environments, high-pressure systems, and pipelines carrying abrasive, erosive, or corrosive media where soft seat materials such as PTFE or elastomers would degrade quickly. Common in steam lines, refineries, and power generation.

What is the function of the manual override on an electric actuator?

The manual override allows operators to open or close the valve by hand in the event of a power failure, electrical fault, or emergency situation. It disengages the electric motor drive and enables direct mechanical operation through a handwheel.

What pressure and temperature ratings are typical?

These valves are typically rated for pressure classes ranging from ANSI Class 150 up to Class 2500, handling pressures up to approximately 420 bar (6,000 psi). Temperature ratings can range from cryogenic conditions (-196°C) up to elevated temperatures exceeding 500°C.

How does the worm gear actuator improve reliability?

A heavy-duty electric worm gear actuator delivers high output torque with smooth, controlled movement. The worm gear mechanism is self-locking, preventing unintended valve movement due to pipeline pressure or vibration, making it highly reliable for automated process control.
