Threaded On/Off Valves for Fuel

- Valve Type: Ball
- For Use With: See table
- Specifications Met:
With Standard Port: Amerian Petroleum Institute Standard 607, Edition 4
With Full Port: Amerian Petroleum Institute Standard 607, Edition 4, Amerian Petroleum Institute Standard 608, ASME B16.34, NACE (National Association of Corrosion Engineers) MR0175
Protect personnel and equipment in the presence of diesel fuel, fuel oil, gasoline, and kerosene. Fire-tested to meet American Petroleum Institute (API) 607, Edition 4, these valves are designed to securely isolate fluid and prevent the spread of fire. They have a lockable handle that can be fixed in place using a padlock (not included).
316 stainless steel valves are more corrosion resistant than steel valves.
Full-port valves do not restrict flow.
Standard-port valves slightly restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

On/Off Valves with Yor-Lok Fittings for Fuel

- Valve Type: Ball
- For Use With: Diesel Fuel, Fuel Oil, Gasoline, Kerosene
- Seal Material: PTFE Plastic
- Specifications Met: ASME B16.34
For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. Designed for transferring diesel fuel, fuel oil, gasoline, and kerosene, these valves have a 316 stainless steel body for excellent corrosion resistance. All are standard port, so they slightly restrict flow.
