1. Nitrogen Blanketing Control for Chemical Storage Tanks
Using the Festo VZXF angle seat valve to regulate the flow of nitrogen into chemical storage tanks to prevent oxidation and explosive atmospheres. The pneumatically actuated valve receives a 6 to 10 bar pilot signal to open and deliver the blanketing gas up to 16 bar.
Problem SolvedReplaces slow-acting motorized valves with a rapid, pneumatically-piloted poppet valve that defaults to a closed, safe state upon air pressure loss. The PTFE seat ensures tight sealing against gas leaks.

2. Low-Temperature Vapour Injection for Industrial Parts Cleaning
Implemented in industrial aqueous parts washers to control the injection of heating vapour up to 80 degrees Celsius. The G1 threaded in-line installation allows seamless integration into the facility vapour lines, while the gunmetal housing resists low-level corrosion stress.
Problem SolvedPrevents vapour leakage and over-pressurization in cleaning baths. The flow direction above valve seat for gaseous media prevents water hammer and ensures stable operation during rapid vapour injection cycles.

3. Main Branch Compressed Air Isolation for Automated Assembly Lines
Acting as a primary 2/2-way safety shut-off valve for automated pneumatic machinery. The valve distributes filtered compressed air to sub-circuits, utilizing its high flow rate capacity of 10.8 m³/h to feed multiple actuators simultaneously without significant pressure drop.
Problem SolvedEliminates the risk of uncontrolled machine movements during emergency stops or power failures. Since the valve is mechanically spring-returned, it automatically shuts off the 16 bar air supply if the externally controlled pilot pressure is interrupted.
