In the pharmaceutical and food & beverage industries, every drop counts. From sterile drug manufacturing to beverage bottling lines, valves are the heart of clean and precise fluid control. The requirements are extremely strict — materials must be hygienic, sealing must be tight, and surfaces must be smooth to prevent bacterial growth or contamination.
Tianjin Dingliu Valve Industry Co., Ltd. provides sanitary-grade valve and automation solutions designed to meet GMP, FDA, and EHEDG standards, ensuring purity, reliability, and efficiency throughout production processes.
Dingliu’s product line for the pharmaceutical and food & beverage industries includes a complete range of hygienic flow-control solutions:
Stainless steel sanitary butterfly valves (manual, pneumatic, electric): designed for easy cleaning and CIP/SIP operations, with polished internal surfaces (Ra ≤ 0.8 μm).
Diaphragm valves: perfect for sterile applications in biopharmaceutical and fermentation systems.
Ball valves with cavity-filled PTFE seats: ensuring zero dead space and preventing medium accumulation or bacterial contamination.
Regulating and control valves: providing precise flow, temperature, and pressure control for process consistency.
Pneumatic and electric actuators: allowing intelligent automation and remote control for modern production lines.
Check valves and filters: maintaining unidirectional flow and preventing contamination in mixing or dosing systems.
All Dingliu valves are available in SS304 / SS316L materials and can be customized to meet 3A, DIN, ISO, or SMS sanitary standards.
In a pharmaceutical cleanroom project in South China, Dingliu supplied 316L pneumatic sanitary butterfly valves and diaphragm valves for a large-scale intravenous solution production line.
Working conditions: 80°C hot water and purified water for injection (WFI).
Challenge: Required ultra-clean design and reliable operation in automated CIP cycles.
Solution: Dingliu designed a fully automated valve network with pneumatic actuators + position feedback control, integrated into the client’s PLC system.
Result:
Cleaning efficiency increased by 30%.
Product purity ensured by mirror-polished internal surfaces and FDA-approved seals.
System achieved 24/7 continuous operation with zero contamination incidents for over 18 months.
Dingliu’s hygienic flow-control solutions are designed to meet the unique challenges of clean production:
Hygienic design: mirror-polished internal surfaces and self-draining structures eliminate residue buildup.
Sterilization compatibility: valves suitable for CIP (Clean-in-Place) and SIP (Steam-in-Place) systems.
Smart automation: integration with process control systems for real-time monitoring and batch traceability.
Material assurance: all seals and elastomers comply with FDA and EU 1935/2004 standards.
Flexible configuration: modular design allows quick replacement, maintenance, and scalability.
By implementing Dingliu’s sanitary valve solutions, manufacturers can achieve:
Reduced cleaning time and water consumption by up to 40%.
Minimized contamination risk, lowering product rejection rates.
Extended valve lifespan due to precision machining and superior corrosion resistance.
Increased process automation, cutting labor and downtime costs.
Dingliu’s hygienic valves not only ensure product purity but also contribute to sustainable production:
Leak-free operation reduces waste of high-value liquids and gases.
Energy-efficient actuators lower power consumption.
Eco-friendly materials and surface treatments comply with environmental and health regulations.
Support for safe steam sterilization and chemical disinfection, protecting both operators and end consumers.
Clients from pharmaceutical plants, dairy factories, and beverage producers across Asia and Europe have shared consistent positive feedback:
“Dingliu’s sanitary valves are as reliable as they are easy to maintain. The polishing quality and sealing performance fully meet GMP standards.”
Another customer stated:
“We replaced imported valves with Dingliu’s products, achieving the same performance at a much lower cost — and their technical team’s response was fast and professional.”
As clean manufacturing moves toward automation and sustainability, Dingliu is investing in:
Intelligent monitoring valves with sensors for pressure, flow, and temperature data.
Eco-smart actuators optimized for low-energy operation.
High-purity diaphragm valves for biotech and vaccine production.
Global partnerships with food and pharma integrators to offer turnkey flow-control solutions.
In industries where purity, hygiene, and safety are non-negotiable, Dingliu’s sanitary valves and automation solutions provide trusted performance for pharmaceutical and food & beverage production.
With advanced materials, precise engineering, and intelligent control systems, Dingliu helps clients achieve stable product quality, lower production costs, and higher regulatory compliance.
As the global demand for clean manufacturing continues to rise, Dingliu remains a reliable partner, ensuring that every flow is pure, every process is safe, and every product is perfect.
