Product information

Description

The Dražice 6422571 safety valve with a 20 mm connection is a vital safety component engineered for water heating systems. Its primary function is to regulate internal pressure, effectively preventing dangerous overpressure conditions within the water heater tank. By maintaining optimal pressure levels, this valve protects the integrity of the heating system, prevents potential leaks or ruptures, and contributes to the overall longevity of your equipment.

Advantages

This safety valve is constructed from high-quality stainless steel, ensuring excellent resistance to corrosion and long-term durability in demanding plumbing environments. Its robust design allows for reliable operation across a wide temperature range, making it a dependable choice for residential and commercial water heating setups. The precise engineering of the valve ensures consistent performance, providing peace of mind by mitigating the risks associated with system pressure spikes.

Suitable for

  • Residential water heating systems
  • Commercial water storage tanks
  • Pressure regulation in hot water circuits
  • Replacement of worn-out safety components in Dražice heaters

When it may not be suitable

This valve is not suitable for systems requiring a pressure rating higher than 6 Bar, as it is specifically calibrated for this limit. Additionally, it should not be used in applications involving aggressive chemical fluids that are incompatible with stainless steel construction.

Key specifications

  • Connection diameter: 20 mm
  • Plumbing connection: 3/4 inch internal thread
  • Material: Stainless steel
  • Maximum operating pressure: 6 Bar
  • Temperature range: 2°C to 90°C

How to use

Installation should be performed by a qualified professional to ensure the system remains airtight and functional. The valve is connected to the cold water inlet of the water heater using the 3/4 inch internal thread. Ensure that the discharge outlet of the valve is directed toward a drain or a suitable collection point to safely manage any water released during pressure relief events. Do not overtighten the connection to avoid damaging the threads.

What to consider before purchase

  • Verify that your system pressure requirements do not exceed 6 Bar.
  • Ensure the 3/4 inch internal thread matches your existing plumbing configuration.
  • Check if your local plumbing regulations require specific safety valve certifications.
  • Confirm the compatibility of the stainless steel material with your water quality.

Usage recommendations

Regularly inspect the valve for signs of mineral buildup or leakage to ensure it remains operational. It is recommended to test the valve periodically according to the manufacturer's guidelines to confirm that the pressure relief mechanism is not obstructed.
