Suction Check Valve Cast Iron With Strainer DIN PN 16
TECHNICAL DESCRIPTION
Bottom valve (suction) with flange connection and check valve. It acts as a filter-suction valve, preventing the fluid from moving in the opposite direction.
• Sealing – metal / EPDM.
• Spring-loaded suction check valve – functions as a one-way valve.
• Connection – flange EN 1092-1
• Installation – vertical position
WORKING FLUID / MEDIUM
• General industrial application – seawater, lubricants, fuels, crude oil, etc.
EXECUTION
• Different materials on request.
• Different NBR/PTFE sealing rings
Our Cast Iron Suction Check Valve with Strainer, designed to DIN standards and rated at PN 16, is engineered for superior performance in demanding industrial fluid systems. This valve ensures unidirectional flow, preventing backflow and protecting pumps and pipelines from damage. The integrated strainer effectively filters out debris, extending equipment lifespan and maintaining system efficiency. Ideal for water supply, irrigation, and industrial applications, it combines durability with reliable operation under high-pressure conditions.Constructed from high-grade cast iron, this valve offers excellent corrosion resistance and mechanical strength, making it suitable for both indoor and outdoor installations. The DIN-compliant design guarantees compatibility with international piping systems, while the PN 16 pressure rating ensures it handles up to 16 bar operating pressures seamlessly. Key features include:Robust cast iron body for long-term durabilityBuilt-in strainer to prevent clogging and protect downstream componentsEasy maintenance and inspection capabilitiesCompliance with DIN standards for reliable interoperabilityInstallation is straightforward, thanks to its standardized flanges and clear flow direction markings. This valve is a cost-effective solution for industries seeking to enhance system safety and reduce maintenance costs. Trust it for applications in water treatment, chemical processing, and HVAC systems, where precision and reliability are non-negotiable.
