## Summary description

Straight check valve by SCHLOSSER, nickel-plated, nominal size DN10 with 3/8"×3/8" threaded connections (model 601300003). Designed to prevent backflow in fluid systems, suitable for plumbing, heating and small-scale industrial applications. The compact nickel-plated body offers corrosion resistance and reliable one-way flow control for pipes and fittings of the specified size.

## Long description

The SCHLOSSER straight check valve DN10 3/8"×3/8" is a nickel-plated one-way valve designed to prevent reverse flow in fluid systems. Its compact body fits standard 3/8" threaded pipe connections and provides reliable directional control for water and other compatible liquids in plumbing, heating and light industrial installations. The nickel-plated finish helps protect the valve body from corrosion and wear in typical indoor and sheltered environments.
Advantages
This straight check valve offers consistent non-return performance with low pressure drop across the valve and a compact form factor that simplifies installation in tight spaces. The nickel-plated surface improves resistance to corrosion and makes the valve easier to clean compared with bare brass. The valve is suitable for use in systems where a dependable, maintenance-minimal one-way flow device is required.
Suitable for
Domestic plumbing installations to prevent backflow
Heating circuits and boiler feed lines
Small-scale industrial or workshop fluid systems
Retrofit or replacement in compact piping assemblies
Key specifications
Valve type: straight check (non-return) valve
Nominal size: DN10
Connection type: threaded 3/8" × 3/8"
Body finish: nickel-plated
Compatible media: water and compatible non-aggressive liquids
Typical applications: plumbing, heating, light industrial systems
How to use
Install the valve in-line with the flow direction marked on the body so that fluid can pass only in the intended direction. Prepare mating threads with appropriate sealing material (such as PTFE tape or compatible thread sealant) and tighten to a torque suitable for 3/8" fittings, avoiding over-tightening that may damage threads or the valve body. Verify system pressure and temperature are within the valve's acceptable operating range for the media used. After installation, check for leaks at ambient pressure and during initial operation.
Usage recommendations
Use the check valve in systems with clean, filtered water or non-corrosive liquids to maximize service life. Avoid installation where particulate-laden fluids, strong acids, or alkalis are present unless compatibility has been confirmed. Periodic inspection during scheduled maintenance is recommended to confirm sealing integrity and freedom of movement of the internal mechanism.
