MULTIVALVE NH3 VALVE 1 1/4″ MNPT X 1 3/4″ ACME

MULTIVALVE NH3 VALVE 1 1/4″ MNPT X 1 3/4″ ACME

Application:

Designed specifically for use as a manual valve or vapor equalizing valve on anhydrous ammonia applicator and nurse tanks. This valve incorporates an integral excess flow valve. When product is required, the valve must be completely open and back seated to allow the excess flow valve to function properly.

Features:

• Positive-acting excess flow valve opens for maximum flow at minimum pressure drop when filling — regardless of the type of coupling in which the valve is installed.
• Excess flow seat is fully contained in the tank coupling for maximum protection in the event of external damage to the valve.
• Resilient seat disc assembly is fully contained on three sides for bubble-tight shut-off and long service life.
• “V”-ring spring-loaded stem seal design requires no repacking or field adjustment.
• Specially machined break-away groove beneath ACME threads will shear-off with excessive pull on the hose and leave the valve body intact.
• Plugged ¼” NPT boss accommodates vent valve or hydrostatic relief valve.
