Jordan Valve - Model Mark 508 Series -Gas Back Pressure Regulator
The Mark 508 Series gas back pressure regulator presented by Richards Industrials is designed to handle low back pressure gas applications. This regulator works efficiently with the Mark 608 in tank blanketing systems, which are crucial for preventing tank over-pressurization by venting excess gas while maintaining a constant protective gas flow to keep the tank atmosphere stable. Its versatility extends to other low back pressure scenarios, facilitated by a body made from durable carbon steel or stainless steel. This regulator offers sizes ranging from 3/4 inch to 2 inches (DN20 to DN50), with connections available in threaded or flanged types. The diaphragm is constructed from Viton material, suitable for handling pressures up to 20 psi (1.7 bar). This device is critical in maintaining safe and optimal conditions in storage tanks and similar systems.
The Mark 508 Series gas back pressure regulator is the ideal valve for low back pressure gas services. The Mark 508 works in conjunction with the Mark 608, in a low pressure tank blanketing valve system. The Mark 508 can be used to vent gas from the tank to prevent the blanketing pressure from rising to a level that could damage the tank while maintaining a small constant flow to keep the blanket fresh. It will also work well in any other type of low back pressure application.
