Product Overview

本产品 Pneumatic High Pressure Ball Valve is designed for Class150~Class2500 (PN20~PN420) ultra-high pressure working conditions, with an integral forged steel valve body and heavy-duty pneumatic actuator as the core. The full series is equipped with GB/ANSI high pressure flanged connection as standard. It drives the ball to rotate 90° pneumatically to realize fast on-off, emergency shut-off and flow regulation of high-pressure pipelines, and can be seamlessly connected to DCS/PLC automatic control systems, with fast switching, pressure and impact resistance, safety and explosion-proof performance.

提供全尺寸规格 DN15–DN400, it strictly complies with global high pressure valve standards including GB, API and ANSI, and is widely used in ultra-high pressure industrial scenarios such as oil and gas wellheads, refineries, power plants, high pressure water treatment, and hydrogen energy storage and transportation.

Key Features

1. Ultra-High Pressure Forged Steel Valve Body

   The valve body is integrally formed from A105, F304/F316 forged steel, with wall thickness reinforced according to the maximum Class2500 pressure rating, 100% non-destructive pressure testing. ensuring stable opening and closing under ultra-high pressure.
