## Summary description

Valvex horizontal check valve model 1903000 is a 3/4" brass non-return valve designed to prevent backflow in plumbing systems. With a horizontal orientation and durable brass construction, it suits domestic and light commercial water installations, ensuring one-way flow in pipelines and protecting pumps, heaters, and other equipment.

## Long description

Valvex horizontal check valve model 1903000 is a 3/4" brass non-return valve designed to maintain one-way flow in plumbing systems. Its horizontal orientation and robust brass body make it suitable for domestic and light commercial water installations where protection against backflow is required. The valve prevents reverse flow that could damage pumps, water heaters, meters, or contaminate potable water supplies.
Advantages
The Valvex 3/4" horizontal model 1903000 offers durable brass construction that resists corrosion in typical water systems and provides long service life under normal operating conditions. Its compact horizontal design allows installation in limited spaces where vertical check valves would be impractical. The valve's straightforward mechanical principle requires no external power or control and delivers reliable one-way flow control with low pressure drop when installed correctly.
Suitable for
Domestic cold and hot water supply lines
Pump discharge lines to prevent reverse flow
Protection of water heaters, meters, and pressure systems
Light commercial plumbing installations with horizontal piping
When it may not be suitable
This horizontal brass check valve is not intended for use with aggressive chemicals, highly acidic or alkaline fluids, or in systems requiring stainless-steel wetted parts. It may not be appropriate where a full bore or swing-type check valve is required for minimal flow obstruction or for very high-temperature steam applications beyond the brass material limits.
Key specifications
Connection size: 3/4"
Orientation: horizontal
Body material: brass
Function: non-return / one-way check valve
Typical application: potable and technical water systems
How to use
Install the Valvex 3/4" horizontal check valve in the pipeline following the flow direction indicated on the body. Ensure that the valve is mounted on a horizontal run and that fittings and thread sealant are compatible with brass. Tighten connections to recommended torque for the chosen thread type, fill and pressurize the system slowly, and check for leaks. Periodic visual inspection is advised; disassemble for maintenance only when the system is depressurized and drained.
What to consider before purchase
Confirm the required connection type and thread standard for compatibility with existing fittings.
Verify that brass is suitable for the fluid and temperature range in your system.
Ensure horizontal orientation is possible at the installation point.
Check that the valve size (3/4") matches the pipeline diameter for optimal flow and pressure performance.
Usage recommendations
Use the Valvex 3/4" horizontal check valve in clean water systems and avoid installation where sediment or debris can accumulate; install upstream filters if necessary. For pumps and equipment protection, position the valve close to the protected device and follow local plumbing codes and manufacturer installation instructions.
