Quarter-turn. Compressed air. 90-degree disc rotation. That is how a pneumatic butterfly valve controls flow. Fast, automated, compact. Key selection factors are actuator type, seat material, body configuration, pressure class, and whether fail-safe is required. PANS Valve manufactures high-performance butterfly valves to ISO 9001, CE, API, and TUV standards for oil and gas, chemical, water […]

Water treatment specs default to resilient seated butterfly valves for a reason. Not sophistication. Just results. An elastomer seat, a rotating disc, bubble-tight shutoff at moderate pressure. Three things working together. Low cost, simple assembly, reliable within its operating range. That is why this valve type shows up on almost every water, wastewater, and HVAC […]
