High Pressure&Large Bore A105 Ball Valve

NSV High Pressure&Large Bore A105 Ball Valve

This ball valve is built for extreme service, featuring an ASTM A105 forged steel body that offers superior strength and impact resistance over cast alternatives. The forging process eliminates internal defects, ensuring structural integrity under high stress. Its trunnion ball design anchors the sphere securely, preventing displacement from line pressure and keeping operating torque low even in critical high-pressure applications.

Key Features

As shown in the figure: This specific unit is rated for Class 1500# pressure with a massive 24" bore size. Which is customizable.

A105 Forged Body: Dense grain structure provides better mechanical properties than casting, handling high shock loads without failure.

Trunnion Ball Design: Upper and lower stem supports stabilize the ball, reducing seat wear and ensuring reliable sealing under high differential pressure.

Emergency Sealant Injection: Equipped with injection fittings to allow emergency sealing or routine lubrication, extending service life in harsh environments.

Fire-Safe Design: Constructed to meet API 607/6FA standards, ensuring a metal-to-metal secondary seal prevents leakage if soft seats are damaged by fire.

Typical Applications

Widely used in oil and gas transmission pipelines, refinery catalytic cracking units, high-pressure hydroprocessing reactors, and power plant boiler feedwater systems. It is ideal for high-temperature, high-pressure media with trace particulates, serving as a primary isolation device in main trunk lines.
