Check valve for various applications

The Zetkama FIG.287/31 DN 65 PN 16 check valve is a reliable device used to protect installations against backflow of medium. The construction of this valve, based on proven solutions, guarantees tightness and long-term operation in demanding conditions. It is an essential element in hot and cold water systems, steam installations and industrial technologies using inert agents.

This valve finds wide application in district heating and refrigeration, as well as in industrial installations where protection against backflow of medium is required. Its solid cast iron construction provides resistance to corrosion and mechanical damage. This makes the valve suitable for both new installations and the modernization of existing systems.

Construction and characteristic features

The Zetkama check valve is characterized by a flanged connection method, which facilitates assembly and disassembly in existing installations. The flanges are drilled according to EN 1092-1 (F execution) and EN 1092-2 (A, C, E executions) standards, ensuring compatibility with various types of pipes and fittings. Compliance with the pressure equipment directive 97/23/EC and the CE marking (for DN≥32) confirm the safety and high quality of the product.

• Tightness of closure: The valve meets the requirements of EN 12334 standard, which guarantees minimal medium losses and efficient system operation.
• Compact design: Compact dimensions facilitate installation even in tight spaces.
• No maintenance required: The valve design does not require regular inspections or maintenance, which translates into saving time and operating costs.
• Built-in length: Compliant with EN 558-1 series 1, which facilitates the replacement of existing valves with the Zetkama model.
• Temperature resistance: Possibility of operation in a temperature range up to 300°C (depending on the version).
• Versatility: Suitable for working with various media - from water to steam and inert agents.

This valve is environmentally friendly and does not require special precautions during use. Its solid construction ensures reliable operation for a long time, minimizing the risk of failure and downtime in the installation.
