What our Experts Think
-
Multifunctional design: Acts as a shut-off valve, non-slam check valve, and flow-throttling valve—all in one unit.
-
Saves space and cost: Combines multiple functions to reduce the need for separate elbows, check valves, and throttling valves, cutting installation labor and piping costs.
-
Durable construction: Made of ductile iron with ANSI 125 flanged connections, capable of handling high pressure and temperature.
-
Convertible configuration: Can be reconfigured on-site from straight to angled to fit changing system layouts.
-
Protects system components: Spring-closure mechanism prevents water hammer, safeguarding pumps and piping.
-
Compact footprint: Three-connection design reduces joints, lowers leak risk, and saves space.
-
Reliable and long-lasting: Balanced weight and construction ensure durability while simplifying installation and maintenance.

Maintenance Tips
-
Inspect valve regularly: Check for leaks, corrosion, and wear on seals and flanges to ensure reliable operation.
-
Clean internal components: Remove debris and buildup to maintain smooth flow and prevent pressure drop.
-
Lubricate moving parts if applicable: Reduce friction and extend valve life.
-
Check flange connections: Ensure bolts are tight and gaskets intact to prevent leaks.
-
Monitor operating conditions: Avoid exceeding pressure and temperature limits to prevent damage.
-
Replace worn components promptly: Timely replacement of seals or seats prevents larger system failures.
