How Does a Brass Horizontal Check Valve Work?
A horizontal check valve is designed to allow flow in the intended direction while restricting reverse flow when system conditions change.
This model uses a disc-type internal closing element. The exact operating characteristics depend on the final product specification and working conditions.
Installation Note: follow the flow-direction arrow marked on the valve body when installing the valve.
Technical Buyer Notes
Confirm the Thread Standard
The valve uses Female × Female threaded connections. The required pipe-thread standard can be specified according to the purchasing requirement.
Buyers should clearly state whether BSPP, BSPT, NPT or another thread standard is required before quotation.
For more information about common thread systems, see our BSP vs NPT thread guide.
Confirmed Size Range: 1/2″–2″
The confirmed product size range is 1/2″–2″. The current product images show examples including DN15, DN25 and DN50.
When requesting a quotation, provide the required quantity for each size rather than only the total order quantity.
PN16 Pressure Class
This product is confirmed as PN16. However, pressure class alone does not define every operating condition.
The actual working medium and operating temperature should also be confirmed before final product selection.
Disc-Type Internal Structure
The currently confirmed internal closing component is a disc.
Detailed disc material, sealing material and other internal component specifications are not currently confirmed and should be checked if they are important to the application.
Application Considerations
This brass horizontal check valve is intended for piping systems requiring one-way flow and reverse-flow prevention.
Final application suitability should be evaluated according to working medium, temperature, pressure, thread standard and installation conditions.
