Spirax Sarco's universal industrial control valves: the core power for industrial automation

With the wave of industrial automation sweeping the world, control valves, as the "nerve center" of process control, have a direct bearing on production efficiency, product quality and operating costs in terms of performance and reliability. With a century of engineering experience, Spirax Sarco Engineering (China) Co., Ltd. has launched a series of general industrial control valves, which provide precise, efficient and sustainable control solutions for various industries with excellent design and innovative technology.

Why Choose Spirax Sarco General Purpose Industrial Control Valves?

In industrial production, a stable and reliable control valve can bring multiple values:

• - Enhancing Product Quality: High-precision control ensures stable process parameters, reduces product fluctuations and guarantees consistency.
• - Improve process efficiency: Accurately regulates fluid flow and pressure, reduces energy loss, and optimizes production rhythms.
• - Reduced overall costs: Durable design extends service life, reduces maintenance frequency and downtime, and significantly lowers total life cycle costs.

Technical Highlights: Innovative Design Drives Superior Performance

Spirax Sarco control valves are designed with details to show engineering strength, and core strengths include:

High precision control and stability

• - Multiple flow characteristics: Provides 4 types of characteristics: equal percentage, linear, modified parabolic, and fast-open, which can be precisely matched to the load to ensure process stability.
• - Intelligent Positioning SystemSP7/SP7 Pro Intelligent Positioner: SP7/SP7 Pro Intelligent Positioner realizes accurate signal conversion, one-key debugging function simplifies the operation, and the air consumption is only 5% of the traditional positioner, and the annual energy saving is up to 474KWh (calculated according to the 8,000 hours of operation).

Durable and low-maintenance design

• - Reinforced stem seal: Precision-machined stem with V-shaped PTFE or high-temperature graphite seals, with self-contained wiper ring cleaning function to prevent the intrusion of impurities and extend sealing life.
• - Wear-resistant construction: Squirrel cage compression seat self-centering design reduces assembly deviation; large flow path design reduces fluid velocity and reduces erosion and noise.

Solutions for extreme conditions

• - noise reduction technology: Continuous absorption of pressure drop energy through multi-stage squirrel cages to keep flow rates within safe limits and reduce aerodynamic noise.
• - Anti-cavitation design: Optimize the flow channel structure to control the pressure within the critical value (Pvc) to avoid cavitation damage to the valve body.
• - Adaptation to special environmentsExtended bonnet for high/low temperature scenarios, stainless steel bellows seal for zero leakage and high temperature requirements.

Driving method: flexible adaptation to automation systems

• - Pneumatic actuatorMulti-spring full rolling diaphragm design, low hysteresis, quick response, optional spring extension/retraction type to ensure safe action in case of air break.
• - Electric actuator::
• - AEL7 Series: Heavy-duty gearboxes with automatic commissioning function, easy to install and suitable for regular working conditions.
• - AEL8 Series: High speed response (4.5mm/s), low energy consumption and low emissions, with status indicator, in line with low-carbon production requirements.
