Introduction

Figure 1. H500 Series Relief Valve Manifold

The H500 Series Combo Joe® relief valve manifold contains four standard style relief valves (either the H280 or H5110 Series) suitable for stationary storage tanks up to 30,000 gallons (113 563 liters). Any one of the four relief valves can be removed for inspection or maintenance without product evacuation of the tank.

Two handles open and close the manifold ports. The handle direction points to the closed port (relief valve). A built-in bleed in the port shutoff mechanism permits a closed port to be quickly reopened.

The H500 Series manifold is available with either brass or steel trim for LP-Gas (propane) or ammonia service.
