Case Study: Globe Valve Performance in Supercritical Steam Applications
Introduction
Supercritical steam applications play a crucial role in industries such as pharmaceutical manufacturing, chemical processing, and food production. When high-pressure steam operates beyond its critical point, it presents extreme challenges in flow regulation, material integrity, and operational efficiency. A major pharmaceutical manufacturing plant in Kenya faced recurring issues with their industrial boiler system, directly impacting production efficiency, energy consumption, and compliance with FDA regulations. Our high-performance globe valves for superheated steam provided the solution they needed to optimize their steam distribution network and improve operational reliability.
The Challenge: Steam Control Issues in a Pharmaceutical Plant in Kenya
Our client, a leading pharmaceutical manufacturer in Africa, relied on high-pressure steam for sterilization, drying, and active pharmaceutical ingredient (API) processing. However, they encountered several critical issues:
* Steam Leakage & Contamination: Frequent internal leakage in control valves led to inconsistent sterilization, risking FDA and GMP compliance.
* Valve Erosion & Premature Failure: The aggressive superheated steam conditions degraded the sealing surfaces, leading to frequent breakdowns.
* Unstable Pressure Regulation: Poor steam flow control resulted in fluctuating steam pressure, affecting sterilization accuracy and process stability.
* High Maintenance Costs & Downtime: The plant replaced their steam valves every 10 months, leading to increased downtime, maintenance costs, and production delays.
Given the strict regulatory standards in pharmaceutical manufacturing, the plant urgently needed a reliable, precision-engineered steam control valve solution to maintain process integrity and reduce operational risks.
Our Solution: High-Performance Globe Valves for Superheated Steam
To address the client’s challenges, we recommended our sanitary-grade globe valves, specifically designed for high-pressure steam control in pharmaceutical applications.

Installation & Implementation
Our team worked closely with the client’s process engineers to ensure a seamless globe valve installation. The process included:
Steam Network Analysis: Reviewing pressure, temperature, and steam flow requirements to determine optimal valve placement.
Customized Valve Selection: Ensuring correct Cv values, trim materials, and actuation type to maximize efficiency in steam pressure control.
On-Site Testing & Validation: Conducting leak detection, pressure drop analysis, and precision flow tests to confirm optimal valve performance.
Long-Term Monitoring & Support: Implementing predictive maintenance strategies to prevent unexpected failures and ensure consistent steam system reliability.
Results: Transforming Steam Control in Pharmaceutical Manufacturing
After integrating our industrial steam globe valves, the pharmaceutical plant saw dramatic improvements in efficiency, regulatory compliance, and cost savings:
Zero Steam Leakage & Contamination-Free Sterilization: Ensured 100% process integrity, protecting product quality and GMP compliance.
Increased Valve Longevity: Service life extended from 10 months to over 4 years, significantly reducing replacement costs.
Stable Steam Pressure & Flow Control: Achieved 99.5% steam process accuracy, eliminating fluctuations in sterilization steam pressure.
Reduced Maintenance Downtime: Optimized performance led to 80% fewer emergency valve replacements, saving thousands in operational costs.
Regulatory Compliance Success: Passed FDA and GMP audits with zero non-compliance issues, ensuring uninterrupted pharmaceutical production.
Client Testimonial: Process Engineer’s Review
“Steam quality is everything in pharmaceutical manufacturing. Our old control valves just couldn’t keep up, leading to quality risks and production delays. Since upgrading to these high-performance globe valves, our sterilization process is rock-solid. We no longer worry about pressure fluctuations or valve failures, and we’ve saved thousands in maintenance costs. The support and expertise from the team were top-notch.”
