Weco® Check Valves

TechnipFMC has redesigned the top entry check valve and added new, proprietary materials. These changes provide improved structural support and erosion tolerance, including added resistance to corrosive chemicals. The result is extended valve life – 2-3X life in acid service or 4-5X life in standard service.
