Check Valves & Strainers

Plumbing Valves Check Valves & Strainers

Welcome to our carefully selected range of check valves and strainers. Here you will find high-quality HVAC components that protect your pipe systems and installations against both unwanted flow directions and harmful particles. Whether you are looking for a reliable bottom valve with strainer basket for suction lines, a robust backflow preventer or a durable brass check valve for the heating system, we have the right products for your installations.

By installing the correct valves and filters, you prevent contaminants from spreading into the drinking water and protect sensitive equipment such as pumps and heat exchangers from wear. Our products come from well-known and established HVAC manufacturers such as Altech, which guarantees a long service life, high precision and safe operation over time in both private homes and commercial properties.

A comprehensive buying guide for check valves and strainers

Choosing the right components for your water and heating system is crucial for the overall function and lifespan of the system. Products in the check valves and strainers category fulfill two unique but complementary functions: they control the direction of movement of the liquid and clear away solid particles that can otherwise cause costly damage to the system's other machines and pipelines.

Benefits of stable control valves and filtration

Investments in quality valves and filters quickly pay off through reduced maintenance costs and increased operational reliability. By integrating these components at strategic locations in the pipe system, you achieve several important benefits:

  • Backflow prevention: Check valves and advanced backflow prevention devices ensure that the liquid can only move in one direction, preventing dirty water from being pushed back into the drinking water pipe.
  • Reduced equipment wear: Foot valves and strainers with integrated strainers effectively capture sand, rust particles and other solid contaminants before they reach pumps or thermostats.
  • Optimized system efficiency: Clean, unblocked pipes provide more even pressure and a more energy-efficient flow throughout the property.

Common applications and uses

These components are used in a variety of plumbing installations in both private homes, holiday homes and industrial premises. Brass foot valves with nylon cone or stainless steel strainer basket are particularly common on suction lines in wells and hydrophore systems to retain the water column when the pump stops. Powerful backflow preventers are installed where there is an increased risk of contamination of the tap water, while standard check valves are installed in heating circuits and circulation systems.

Important to consider before your purchase

In order for your new components to function optimally, there are some technical parameters you need to check before ordering:

  • Dimension and thread type: Check whether your system requires internal or external thread and which dimension (for example G15, G20, G25 or larger) matches your existing pipes.
  • Material selection: Brass components offer excellent corrosion resistance and mechanical strength, making them ideal for most water-borne systems.
  • Flow requirements and pressure classes: Ensure that the valve is dimensioned for the working pressure and temperatures that occur in your specific installation.
