LMI 4" Function Valve 48798

Description

The Four Functions:

• Anti-Siphon - The discharge flow path goes through a port that only opens on the discharge stroke of the pump. This prevents the discharge line from siphoning liquid from the supply tank in most applications.
• Back Pressure - The diaphragm that controls anti-siphoning creates approximately 20 psi (1.4 Bar) back pressure on the pump's discharge valve which improves system performance.
• Pressure Relief - A second diaphragm protects the pump from overpressure by releasing fluid to a relief port in the event of excessive discharge line pressure.
• Pressure Release - This function makes it easy and safe to depressurize the discharge line without loosening tubing or fittings.

**Valve comes with 1/2" MNPT connections. The appropriate sized tubing connection kit must be ordered separately**
