RegO Internal Valves

RegO internal LPG valves are easily installed and designed to enable smooth operation and higher pumping rates without cavitation or loss of efficiency to save you time and money. They have safety features such as a built in excess flow function and protection against external damage—all critical operating components are located in the valve body. If sheared off the remaining components stay in the tank.

RegO internal LPG valves require maintenance less often than other internal valves, and the maintenance is fast and easy. We pay attention to the details, such as superior corrosion prevention and securing fasteners so they don’t come loose and cause damage.

RegO internal valve options:

  • Threaded, flanged, and double flanged options
  • Threaded versions can be installed in full or half couplings
  • Manual, pneumatic, rotary, and electric activation

RegO Globe Valves

RegO globe valves are constructed with high-quality materials and come in a range of sizes for use in LPG bobtail and tanker truck applications. Purposefully designed to ensure greater flow with no pressure drop, positive shut-off and long maintenance-free service, our globe valves provide safety and peace of mind for years. RegO globe valves include these standard features:

  • “V”-ring spring-loaded pressure stem seal provides for leak-proof operation, with no packing to re-tighten or replace, while virtually eliminating hard-to-turn handles.
  • Swivel seat disc assembly stops rotating as soon as it touches the body seat to deliver good seat alignment and long life.
  • Size ranges: 1/2″ to 3″ F. NPT, and 1 1/2″, 2″ & 3″ flanged versions

RegO Transport Components

Back Pressure Check Valves

A3146 Series A3186 Series

RegO Back Pressure Check Valves are designed to allow flow in one direction only. When the flow stops or reverses, the check closes. Built to provide generous flow channels for low pressure drop, the heavy-duty construction and synthetic rubber seat discs deliver positive seals for years.


Pressure Release Valve

A8430 Series

These low profile, internal relief valves are constructed of non-corrosive materials and the RegO “pop-action” design ensures maximum protection.


External Hydrostatic Relief Valves

3125 Series
3127 Series
3129 Series
SS8000 Series

Protects piping and shut-off valves against possibility of trapping LPG. Automatically reseats firmly after discharge, provides a “bubble-tight” seal, and available in both brass and stainless steel.


Rotogage® Assemblies 

A9090 Series

Designed to provide an accurate determination of LPG container contents, they mount in a standard 1” NPT coupling. Resistance-free nylon bearing inserts reduce friction and promote operating ease, and the dial face is dual calibrated to provide greater accuracy in reading contents in containers which are not level.


RegO Hose End Valves

Hose End Valves

A7797A Series
A7793A Series


The A7797A and A7793A Series vastly reduces the amount of product vented when disconnecting bobtail delivery trucks, dispensing systems and anhydrous ammonia nurse tanks. These valves provide instant, full-on flow at the flip of a handle. Shut-off is instant and the handle locks for added protection.


  • Minimizes product venting loss when disconnecting, instantly by housing the seat disc at the bottom of the built-in ACME filling connector
  • V-Ring spring loaded pressure seal design provides for dependable leak-free operation
  • Low emission design minimizes product venting loss when disconnection
  • Vents less than 2cc of liquid when used with RegO low emission fill valve
  • Self-locking handle helps prevent accidental opening of the valve
  • Operator friendly contoured handle rotates 360°, large filling grip connector is easy to use
  • Easily field-maintained

Hose End Valves

A7914A Series


The A7914A Series low emission valve is designed to reduce the amount of product vented when disconnecting bobtail and transport loading hoses. Press the release trigger while lifting the easy-grip handle for full-on flow, lower the handle for an immediate stop and lock. This valve can be used with any standard 31⁄4″ Male ACME connector, or our 6588LE and 6589LE minimum loss filler valves.


  • Vents less than 2 cc of liquid when disconnected from a 6588/89LE low emission ACME Adapter. California CARB Compliant
  • Self-locking handle is operator opened and closed, designed to prevent accidental opening of the valve
  • Contoured handle rotates 360°, large easy-to-turn ACME swivel connector
  • Protective screen on inlet side prevents debris from entering
  • Spring-loaded Teflon “V” packing for bonnet/stem assembly provides long service life

Low Emission ACME Adapter

6588LE Series
6589LE Series


The 6588LE/6589LE Series low emission ACME adapter is UL listed and designed for use with the A7914A hose end valve. When used together, they provide fast filling of LPG bobtails, transports, and large bulk storage tanks, and a low-emission disconnect.


  • 31⁄4” Male ACME adapter reduces emissions at disconnect to just 10.5 cubic centimeters of LPG
  • Safety groove is designed to shear below ACME threads leaving the valve seat closed and unaffected if the vehicle pulls away with the hose connected
  • Seat disc is made of synthetic composition and is mechanically held in place by a seat disc retainer
  • Stainless steel return spring, one-piece poppet stem for smooth operation
  • Hydrostatic relief valve included (3125L)

Extended Type Hose Couplings

A7570 Series

Simplified, yet rugged design eliminates an extra joint and provides smooth, uninterrupted flow and stands up to repeated use. The free swivel action between tailpiece and handle allows for easy make-up, while the limited travel of the handle on the tailpiece minimizes spin-off, encouraging cautious removal to properly bleed off trapped product to ensure closure of the filler valve and hose end valve.
