Pressure/Vacuum Relief Valves
Anderson Greenwood Type 4040 Piped Away Pressure and Vacuum Valves
Overview
Weight or spring loaded valves capable of providing pressure and vacuum relief that pipe away to a closed header system.
Designed to work closer to a tank's MAWP, increasing productivity, reducing emissions and product evaporation

Data Sheets & Bulletins
Data Sheets: Type 4040 piped away pressure and vacuum relief valves, Anderson Greenwood-EN
Features
Increased flow capacities reduce the required valve size and the corresponding connections and piping costs.
Fully open at 10% overpressure, enabling setting close to MAWP/MAWV and minimizing tank emissions.
Large body for increased capacity providing high flow performance for full conformance to API2000/ISO28300.
Leakage rate of 0.5 scfh (0.015 Nm3 /hr) or less at 90% of setpoint.
Weight or spring loaded models available.
Choice of body materials.
Modular design enables all components to be removed and replaced in-situ for quicker, simpler maintenance.
Optional ‘all-weather’ coating prevents frozen condensate build-up and sticking of vital components in cold weather applications.
