Installation & Maintenance Tips
For optimal performance, install the valve in a horizontal position with the arrow on the body aligned with flow direction. A strainer should be placed upstream to protect the valve from debris. Regularly inspect the pressure setting and clean the internal strainer as needed. All threaded connections should be sealed with appropriate thread sealant. For flanged connections, use gaskets conforming to the pressure rating.
