Industrial-Grade Diaphragm Control for Corrosive Environments

Corrosion-resistant BSPP weir diaphragm valves with PTFE diaphragms are engineered for sectors that demand robust, contamination-free flow control. These valves solve a widespread challenge in process engineering—equipment degradation due to chemical exposure. PTFE’s superior chemical inertness, paired with BSPP threading, delivers leak-tight performance even under aggressive media conditions. With a strong track record in flow control solutions, our valves are trusted in facilities worldwide for their precision, durability, and ease of maintenance.

Technical Specifications & Global Standards
Our BSPP weir diaphragm valves are offered in DN15–DN100 sizes, manufactured according to EN 558-1 Series 1 and compatible with common DIN standards. Each valve includes a PTFE diaphragm and body linings such as ETFE, vulcanized rubber, or glass, chosen based on the media handled. Pressure ratings up to PN10 and temperature resistance up to 180°C provide flexible performance. All valves conform to ISO 9001 manufacturing standards and carry CE and ATEX certifications, ensuring reliable use in safety-critical systems. For more corrosive applications, our glass-lined diaphragm valves offer an excellent upgrade.
