Product Overview
The vapor recovery valve is a critical part of the vapor recovery system used on fuel tankers to reduce vapor emissions and maintain safety during fuel loading and unloading. It is installed on the manhole cover and allows safe redirection of fuel vapors during transfer, helping to minimize vapor loss, protect the environment, and ensure compliance with emission regulations.
Engineered for pneumatic operation, this valve is installed directly on the manhole cover or on the top of the tanker. It includes a lift-type internal valve that opens into the tank and automatically seals in case of vehicle rollover or excessive pressure, helping to prevent fuel spillage and product loss in accidents.
The tank truck valve is built for long-term durability and minimal maintenance, with high-grade stainless steel internal components and a lightweight aluminum alloy body that withstands the demanding conditions of vapor handling in the petroleum transport industry.
Features
- Lightweight aluminum alloy housing for corrosion resistance and structural strength.
- 50% longer valve stroke reduces pressure loss and improves system flow efficiency.
- Enhanced spring tension enables faster and smoother valve closure.
- Dual fluorosilicone piston O-rings, along with improved lower shaft seals and wipers, protect the air system from vapor intrusion.
- New external air exhaust port ensures quicker valve actuation and response time.
- Threaded cap design eliminates the need for snap rings, simplifying installation and maintenance.
- Optimized flow performance with reduced pressure drop across the valve.
- Compatible vapor piping lengths:
H7061000002 – 395 mm
H7061100002 – 305 mm
H7061200002 – 160 mm

How is the pressure of a vapor recovery valve adjusted?
How is the pressure of a vapor recovery valve adjusted?
The pressure is adjusted by rotating the adjustment nut, which changes the spring tension. A tighter setting results in a higher pressure threshold. Pressure adjustments should be made according to the equipment specifications and user manual, and care must be taken not to overtighten, as this may damage the valve or cause unstable pressure regulation.
What is a vapor recovery system in a fuel tanker?
What is a vapor recovery system in a fuel tanker?
A vapor recovery system is designed to control internal tank pressure and capture hydrocarbon vapors released during fuel loading and unloading. By containing and redirecting these vapors, the system helps minimize emissions and prevent environmental pollution, while also supporting regulatory compliance.
