Pressure Relief Valve -TKSAGE

Product Overview

The Pressure Relief Valve TKSAGE is a high-precision control valve engineered for maintaining stable pressure in cleanrooms, HVAC systems, and biosafety facilities. Designed with a 316L stainless steel valve body and PTFE sealing, it adjusts pressure within ±0.1Pa accuracy across ranges of -500Pa to +1000Pa. The diaphragm-operated design ensures fast response (≤0.5 seconds) to pressure fluctuations, preventing air leakage and maintaining cleanliness integrity. Compliant with ASME B16.34 and ISO 9001, it’s compatible with aluminum, galvanized, and stainless steel ductwork—ideal for pharmaceutical, semiconductor, and biotech environments.

Scenario-Based Solutions

Pharmaceutical Cleanroom Zones

In multi-zone cleanrooms (Grade A/B/C/D), the valve maintains differential pressure (10-15Pa between zones) to prevent cross-contamination. Its precise control ensures consistent airflow, supporting GMP requirements for sterile production.

Semiconductor Cleanrooms

In Class 1-100 semiconductor facilities, the valve stabilizes pressure in lithography rooms, preventing particulate ingress from adjacent areas. The corrosion-resistant 316L body withstands harsh cleaning agents (e.g., isopropyl alcohol).

Biosafety Laboratory HVAC

In BSL-3/4 labs, the valve maintains negative pressure (-50 to -100Pa) relative to external areas, containing hazardous pathogens. The fail-safe design closes automatically during power outages, ensuring safety.
