Product Overview

This High Pressure Electric Ball Valve is tailor-made for Class150~Class2500 (PN20~PN420) ultra-high pressure working conditions. Its core adopts two key configurations: integral forged steel trunnion mounted valve body + heavy-duty intelligent electric actuator. The full range from DN15 to DN400 adopts trunnion mounted double seat structure, equipped with GB/ANSI high pressure standard flanged connection as standard.

Driven by the electric actuator, the ball rotates 90° to realize remote on-off control, emergency shut-off and flow proportional regulation of high-pressure pipelines. It can be seamlessly connected to DCS/PLC industrial automatic control systems, with precise control, fast response, pressure and impact resistance, safety and explosion-proof performance.

It strictly complies with global high-pressure valve industrial standards including GB/T 12237, ANSI/ASME B16.34 and API 6D, and is widely used in ultra-high pressure automation working conditions such as oil and gas long-distance pipelines, refinery hydrogenation units, chemical high-pressure synthesis, power plant high-pressure systems, and hydrogen energy storage and transportation.

Key Features

1. Ultra-High Pressure Exclusive Trunnion Mounted Forged Steel Valve Body

   The full range uniformly adopts trunnion mounted double seat structure. The ball is accurately positioned by fixed support shafts on the upper and lower sides, with no radial offset and no extrusion deformation under ultra-high pressure working conditions, ensuring constant and stable opening and closing torque. It completely solves the industry pain points of valve jamming and uneven wear of sealing surface under high pressure.

   All core pressure-bearing parts such as valve body and bonnet are integrally formed from A105, F304, F316 high-pressure special forged steel, without casting defects. With wall thickness redundancy reinforced design according to the maximum pressure rating of Class2500, 100% of the products have passed ultrasonic flaw detection, hydraulic pressure test and air tightness test, completely eliminating the risk of valve body leakage and deformation under ultra-high pressure working conditions.

2. Heavy-Duty Electric Actuator for High Pressure Conditions, Intelligent & Precise Control

   The core is equipped with a heavy-duty quarter-turn electric actuator exclusive for high pressure ball valves, fully focusing on the core control demand of electric actuation, optimized for high pressure working conditions:

   Heavy-duty high torque design, the output torque accurately matches the high pressure opening and closing demand, with stable opening and closing without impact, suitable for driving high pressure ball valves of full range DN15~DN400;

Full control mode coverage: on/off type / regulating type (4-20mA/0-10V analog) options, supporting local manual operation, remote DCS/PLC system linkage, Modbus/Profibus bus communication, realizing remote precise control of high pressure pipelines;

Multiple safety protection: built-in over-torque, overheat, overload, anti-jam and anti-reverse protection, automatically triggers shutdown protection under abnormal working conditions to avoid damage to the actuator and valve body under high pressure; standard equipped with real-time valve position feedback and fault alarm function, realizing full-process visual management and control;

High protection & explosion-proof adaptation: standard IP67 protection grade, optional IP68 waterproof grade; optional explosion-proof actuator with explosion-proof grade ExdⅡBT4/CT4, perfectly suitable for flammable and explosive high pressure working conditions such as oil and gas, chemical industry; built-in emergency manual handwheel for manual opening and closing under power failure and fault conditions, ensuring the safety of emergency operation of high pressure pipelines.

1. Special Sealing Structure for High Pressure, Bidirectional Zero Leakage

   Special sealing optimization for ultra-high pressure working conditions, full coverage of two sealing options: soft seal type adopts high-pressure reinforced PEEK/PPL valve seat with built-in disc spring constant pressure preload, suitable for Class150~Class1500 medium and high pressure working conditions, reaching ANSI B16.104 Class VI bidirectional zero leakage; metal hard seal type sealing surface is overlaid with Stellite hard alloy / tungsten carbide, after high-precision paired grinding, the surface hardness reaches HRC45-65, resistant to ultra-high pressure erosion, wear and high temperature, full pressure coverage from Class150 to Class2500 maximum grade, reliable shut-off in both forward and reverse directions.
