Gate valve GLO Fig. 215 DN50 PN16, gray cast iron EN-GJL-250, construction: 32, swing-check type, loose disc with spring, stem-brass, disc and body ring-bronze 215A050C32

Gate valve made of gray cast iron, with nominal diameter DN50 and pressure class PN16, is a reliable solution for protecting installations against medium flow. The design featuring a loose disc with a spring ensures tightness and minimizes the risk of damage caused by water hammer. The 32 version, i.e., the gate-check valve, additionally prevents backflow.

Construction and Materials

The valve features a robust construction. The body is made of gray cast iron EN-GJL-250, ensuring strength and corrosion resistance. The stem, manufactured from brass, guarantees smooth operation, while the disc and seat ring made of bronze provide high sealing performance and durability. This careful selection of materials ensures long service life even under demanding operating conditions.

Application and Compatibility

This valve finds wide application in various systems:

• Hot, cold, and cooling water systems
• Steam systems
• Industrial processes
• Heating and power systems

It is suitable for use with water and other liquids (in accordance with technical parameters). Compliance with standards EN 12266-1 and EN 558-1 (Series 1) allows safe use in modern installations. Additionally, it meets the requirements of the Pressure Equipment Directive 97/23/EC and carries CE marking for diameters from DN32 upwards.
