Check-and-Shut-off Valve – Reliable Protection and Flow Control

The check-and-shut-off valve ZGLO Fig. 215C is a versatile device combining the functions of a check valve and a shut-off valve in a single integrated unit. It provides effective protection against backflow and enables complete isolation of the medium flow. This is particularly critical in systems where flow direction must be strictly controlled, and reverse flow could lead to damage or process disruption.

The valve’s design stands out due to the use of high-quality materials: the body is made of ductile iron, ensuring strength and corrosion resistance. Critical internal components—including the stem, poppet, and seat ring—are manufactured from stainless steel, guaranteeing long-term reliability and resistance to aggressive media. The 31 design features a loose poppet with a spring, ensuring smooth operation and tight sealing.

This valve is suitable for a wide range of industrial and utility applications—from water supply and sewage systems, through heating and cooling installations, to technological processes requiring precise flow control. With flanged connections DN200 and pressure class PN25, this valve is ideal for applications demanding high performance and safety.

• Versatility: Combines check valve and shut-off valve functions in a single unit.
• Durability: Ductile iron body ensures resistance to pressure and corrosion.
• Reliability: Stainless steel internal components ensure long service life.
• Leak-tightness: Loose poppet with spring design ensures secure flow closure.
• Universal application: Broad application range across multiple industrial and construction sectors.
• Safety: Protects installations against backflow and potential damage.

This valve complies with PN 25 standard, confirming its high quality and safe operation. Flanged connections simplify installation and removal in existing systems. Thanks to precise manufacturing and durable materials, the ZGLO Fig. 215C check-and-shut-off valve represents a reliable solution for demanding users.
