Strainers in an angled Y-shape are indispensable components for protecting piping systems and valves from contamination. They are used in the energy, chemical, petrochemical and process industries to reliably separate particles from liquids, gases and steam. The Y-shape enables a compact design, low pressure loss and easy maintenance. Our selection includes models for standard and high-pressure applications, aggressive media and compact installations.

For standard, high-pressure and special applications.
DIN EN 1092, EN 558, Pressure Equipment Directive 2014/68/EU.
Robust materials, tested gaskets.
Heating jacket, differential pressure indicator, special connections.
Easy cleaning and sieve replacement.
Our Y-strainers with angled seat can be fitted with a heating jacket or leakage jacket on request. This modification is the ideal solution for applications where temperature stability and additional safety are required.
We manufacture customized strainer inserts in different mesh sizes for strainers. These strainers are available as original spare parts or consumables and ensure optimum filtration for your specific process requirements.
Available mesh sizes: 0.1 mm (for finest particles and highest purity), 0.25 mm, 0.6 mm, 0.8 mm, 1.2 mm, 2 mm, 10 mm (for coarse particles and high flow rates)
In addition to the standard version, we offer extensive modifications and retrofits for your strainers – both for our products and for third-party brands. This allows us to optimally adapt your valves to the requirements of your system.
Special feature:
We also offer all services for strainers supplied by you or products from third-party suppliers.
For the filtration of aggressive media and the protection of sensitive process fittings in complex systems.
Ensures operational safety in high-pressure and high-temperature circuits for steam and water.
Removes particles from crude oil, gas and lubricating oil circuits to protect pumps and heat exchangers.
Hygienic filtration for liquids and process water, compliant with high purity requirements.
Ensuring cleanliness in production processes with corrosion-resistant stainless steel strainers.
Protection of pipes and valves in water treatment and descaling systems.
Liquids, gases and steam – even aggressive media in stainless steel versions.
All models are designed for easy sieve removal, some with quick release or swivel device.
