Volumetric Shut-off Valves

Volumetric shut-off valves allow a set amount of water to flow before automatically closing the valve. Perfect for filling large storage tanks, sprayer tanks, flushing or other applications where a specific amount of water needs to flow before stopping. Must be manually reset after each run.

Operation is extemely simple and does not require electricity to operate.

The 250 & 500 gallon units are adjustable by 10 gallon increments and feature 3/4" BSPT connections.

The 2,500 gallon unit is adjustable by 100 gallon increments and features 1" BSPT connections.

User Instructions:
NOTE: There must be available flow through the valve and system to check and adjust valve. Insure that a downstream demand is created by opening field valves, sprinklers, etc. Please verify that the unit is installed according to the flow direction. (large arrow on the top body)

 
1. Close main valve by fully turning setting knob on top of the valve counter-clockwise until dial face is on zero exactly in front of the small body arrow pointing at the dial and clicks.
2. Open fully the upstream gate valve but open gate the downstream gate valve only slightly (if applicable). Main valve should remain closed.
3. Slowly turn setting knob on top of the valve. Turn it counter-clockwise to the desired volume on the dial face aligning the desired volume with small arrow on the valve body.
4. Open the downstream gate valve fully (if applicable) and valve should open completely for normal operation.
