Relief Valve Types

RegO Fully Internal Pressure Relief Valve for DOT Forklift Cylinder

Designed for use as a primary relief valve on forklift cylinders, the 8545AK reduces the possibility of improper functioning of the relief mechanism due to foreign material build up.

See our line of Internal Relief Valves Online.

RegO External Hydrostatic Relief Valves

Designed especially for the protection of piping and shut-off valves where there is a possibility of trapping liquid LP-gas or anhydrous ammonia. They may be installed in pipelines and hoses located between shut-off valves or in the side boss of RegO shut-off valves.

See our line of Internal Relief Valves Online.

RegO Vapor Relief Valves

Designed for use as a relief valve on first stage regulators with a rated capacity of more than 500,000 BTU/hour as per NFPA 58 2.5.7.5.

See our line of Vapor Relief Valves Online.

RegO Internal Relief Valves for Transports and Delivery Trucks

Fully Internal "Pop-Action" Pressure Relief Valves for Transports and Delivery Trucks. Designed specifically for use as a primary relief valve with ASME transports and delivery trucks with 2" and 3" NPT couplings. All stainless steel construction.

See our line of Internal Relief Valves Online.

RegO Internal Relief Valves for ASME Containers

Semi-internal "Pop Action" Pressure Relief Valves. Designed for use as a primary relief valve on ASME containers such as 250, 500, and 1,000 gallon tanks.

See our line of Internal Relief Valves Online.

RegO Internal Relief Valves for Large Storage Containers

Semi-internal "Pop Action" Pressure Relief Valves. Designed especially for use as a primary relief valve on large stationary storage containers, these low profile relief valves are generally mounted in half couplings.

See our line of Internal Relief Valves Online.

RegO Relief Valves for Motor Fuel Containers

8543 Series relief valves are designed for use as a primary relief valve in larger ASME motor fuel containers such as on buses, trucks and construction equipment.

8544 Series relief valves are designed for use as a primary relief valve in smaller ASME and DOT motor fuel containers such as on tractors, lift trucks, cars and taxicabs.

See our line of Internal Relief Valves Online.

RegO Duo-port Pressure Relief Valve Manifolds for Small Storage Containers

Designed especially for use as a primary relief device on smaller stationary storage containers up to 1200 gallons water capacity, with 2” NPT threaded couplings.

See our line of Internal Relief Valves Online.

RegO Multiport Pressure Relief Valve Manifold Assemblies for Large Storage Containers

Designed especially for use as a primary relief device on large stationary pressurized storage containers with flanged openings. These manifolds incorporate an additional relief valve, not included in the flow rating, allowing for servicing or replacement of any one of the relief valves without evacuating the container. The handwheel on the manifold selectively closes off the entrance port to the relief valve being removed while the remaining relief valves provide protection for the container and its contents. All manifold flow ratings are based on flow through the relief valves after one has been removed for service or replacement.
