Festo Pressure Relief Valve, One Way, 0.3 to 10 Bar Operating Pressure - GRLZ-1/4-RS-B

Stop pressure buildup in your pneumatic airways with this pressure relief valve from Festo. Its one-way function safely exhausts air when your system's pressure climbs too high, automatically preventing damage to your equipment from overpressures. As the device achieves nominal flow rates up to 820L/min, it gives you efficient pressure management. The unit has a G1/4 thread inlet port, so it's widely compatible with standard compressed-air supplies. With its convenient knurled screw, this product lets you precisely control your system's flow rates.

• Airtight NBR seal eliminates risk of leakage for consistent system pressure

• Performs at operating pressures between 0.3 and 10 bar to suit many pneumatic applications

• Nickel-plated brass body resists corrosion for use in damp areas

• Suitable for use with lubricated air for versatility

Applications

• Water treatment facilities

• Pumping stations

• Battery manufacturing

• Pharmaceutical industry
