Description
PRM ARV-34A Vapor Recovery Breakaway Valve
The PRM ARV-34A Vapor Recovery Breakaway Valve is a reusable safety coupling installed between a vapor recovery fuel nozzle and hose. If a vehicle drives away while still connected, the coupling is designed to separate at a controlled force and seal the fuel circuit, helping protect the fuel dispenser, hose assembly, nozzle and vehicle.
Designed for gasoline vapor recovery systems, the ARV-34A combines a compact structure, M34 x 1.5 connection and durable sealing components for petrol station equipment manufacturers, maintenance teams and fuel dispenser retrofit projects.
Product Introduction
A drive-away incident can damage the nozzle, hose and dispenser, creating downtime and potential fuel leakage. The PRM Vapor Recovery Breakaway Valve provides a designated separation point in the dispensing hose assembly.
The ARV-34A uses connected inner and outer joint structures. The central section contains the vapor passage, while the outer section carries the fuel passage. When excessive pulling force is applied, the joint separates and the fuel-side connection self-seals to help prevent leakage.
Unlike a disposable safety device, this Vapor Recovery Breakaway Valve can be inspected, correctly reconnected and reused after separation when no damage is found. This helps reduce replacement cost and restore dispenser availability.

Key Features
Controlled breakaway protection
The ARV-34A separates when abnormal pulling force reaches the designed range, helping limit damage caused by accidental vehicle drive-away incidents.
Fuel circuit self-sealing
After separation, the fuel-side joint is designed to self-seal, helping reduce fuel leakage risk and improve on-site safety.
Vapor recovery system layout
The product is structured for vapor recovery hose assemblies, with separate internal vapor and fuel flow paths.
Reusable safety coupling
After a separation event, the coupling can be reused when it passes inspection and is correctly reassembled. This reduces unnecessary replacement cost.
Durable corrosion-resistant finish
The galvanized surface helps resist corrosion and oxidation in regular petrol station operating environments.
Reliable sealing components
Fluorinated nitrile rubber sealing rings are used to support long-term sealing performance in compatible gasoline service.
Electrical conductivity
The coupling is designed with conductive performance suitable for its intended fuel dispenser application.
Applications
The PRM ARV-34A Vapor Recovery Breakaway Valve is suitable for:
Product Details
M34 x 1.5 connection
The ARV-34A uses an M34 x 1.5 threaded joint. Confirm nozzle, hose and swivel thread specifications before ordering.
Inner and outer joint structure
The inner and outer joints form the designed breakaway point. This is the key structure that releases under excessive force.
Vapor and fuel passages
The center section accommodates the vapor path, while the outer structure is arranged for fuel flow. This supports integration with vapor recovery hose systems.
Sealing ring
The fluorinated nitrile rubber seal supports reliable sealing performance. Replace seals if damaged, aged or incompatible with the actual fuel application.
Installation and Maintenance
Install the ARV-34A between the compatible vapor recovery nozzle and hose according to the dispenser assembly drawing. Do not force mismatched threads or use damaged seals.
After any drive-away or separation event, stop dispensing and inspect the breakaway valve, nozzle, hose, swivel and dispenser connection before returning the system to service. Do not reconnect a valve with visible cracks, deformed threads, worn locking parts or damaged seals.
Keep the connection area clean. Periodically check for leakage, corrosion, loose threads and wear. Installation and maintenance should be performed by qualified fuel equipment personnel.
Quality, Packaging and Procurement
PRM lists sealing tests and tensile tests before delivery for the ARV-34A series. Certification availability, destination-market compliance documents and final packing requirements should be confirmed with PRM before placing an order.
Standard reference packing is one piece per box. For bulk orders, request the confirmed carton quantity, gross weight, export carton specification and any required wooden packaging.
FAQ
What happens if a vehicle drives away with the nozzle connected?
The breakaway valve is designed to separate at 800-1500 N and self-seal the fuel-side circuit, helping limit damage and leakage.
Can the ARV-34A be reused after separation?
Yes, it is designed as a reusable coupling. It must be inspected carefully and correctly reconnected before reuse.
Is the ARV-34A compatible with every nozzle?
No. Confirm the M34 x 1.5 thread, hose construction, vapor recovery arrangement and dispenser drawing before purchase.
What fuel system is it designed for?
It is intended for compatible gasoline vapor recovery dispensing systems. Confirm compatibility before use with alternative fuels or special blends.
Can PRM provide OEM service?
OEM supply, packaging and project-specific product configuration can be discussed before production.
