Item # 40-28, Rate of Flow Control and Fuel Shut-off Valve

  • Positive Flow Limitation
  • "Fail Safe" Construction
  • Closes Tight on Signal From Float Control
  • Adjustable Maximum Flow Rate Setting
  • No Packing Glands Assure Leak-Proof Service
  • Position Indicator is Standard Equipment
The Cla-Val Model 40-28 Rate of Flow Control and Fuel Shut-off Valve limits the flow to a pre-set maximum and also closes quickly in response to a signal from the Float Control of a Fuel-Water Filter/Separator, it is a hydraulically-operated, pilot controlled, diaphragm-type, globe valve. Should the diaphragm become damaged the valve will close tight, pro viding "fail safe" operation.

The rate of flow control pilot is actuated by differential pressure produced across a calibrated stainless steel orifice plate installed at the valve inlet. The flow rate setting is adjustable from 90 percent to 112 percent of rated capacity of the Filter/Separator. This Valve has an accuracy of plus or minus 5 percent of the adjusted rate setting. An auxiliary 3- way diaphragm control pilot provides immediate response to operating pressure signal from the Float Control.
