Neles B1 Series: The Heart of Industrial Valve Automation
I. Dual-Power Performance for Critical Operations
The Neles B1 series sets the benchmark for quarter-turn piston actuators, offering two distinct configurations: the double-acting B1C series and spring-return B1J series. The B1C delivers torque outputs from 40 Nm to 100,000 Nm at 10 bar (145 psi) supply pressure, ideal for processes requiring continuous control. Meanwhile, the B1J series provides fail-safe operation (fail-open/close) with 25-12,000 Nm torque at 8.5 bar (124 psi), making it the go-to choice for emergency shutdown (ESD) systems in high-risk industries.
II. Design for Universal Application
Extreme Environment Resilience Constructed with cast iron housing and anodized aluminum cylinders, the B1 series operates seamlessly across -40°C to +120°C. Enhanced Arctic versions (-40°C to +70°C) ensure reliable performance in oil/gas extraction and polar pipeline networks. Its IP66/IP67 rating and stainless-steel travel stops provide superior protection against dust, moisture, and corrosive media.
Intelligent Adjustment & Precision Control Standard adjustable travel stops (85°-95° standard, 0°-90° optional) integrate with Neles’ ND9000 smart positioner, achieving ±0.5% positioning accuracy and millisecond response times. This excels in applications like petrochemical reactor flow regulation and power plant steam valve control.
III. Total Lifecycle Value
Minimal Maintenance The built-in wear-resistant bearings and modular spring cartridge design extend maintenance intervals beyond 5 years. Coupled with Neles’ Predictive Maintenance system, real-time vibration/temperature analytics preempt equipment failures, reducing unplanned downtime.
Certifications & Compliance The series meets EN 15714-3 (industrial valve actuator safety) and ATEX certification (Ex II 2G/D c IIC TX), ensuring safe operation in explosive atmospheres. Full ISO 9001 compliance from design to production guarantees adherence to Industry 4.0 standards.
