Manual manifolds are designed to deliver process or laboratory gases at a constant pressure throughout a gas supply system There are two types of manual manifold systems. The first type of system has a single master valve with an attached pressure control regulator. This particular type of manifold is specifically designed to increase the capacity of an existing single cylinder gas supply system by allowing the use of multiple cylinders, often referred to as a cylinder bank. The Second type of manual manifold utilizes two master valves with an attached pressure control device. While this type of system also increases the capacity of an existing single cylinder gas supply system it also allows the user to manually switch from a depleted cylinder bank to a full cylinder bank. The ability to switch between banks with the simple turn of two master control valves allows for virtually uninterrupted gas supply. When the master valve for the depleted cylinders is closed they are isolated from the system and can be changed while the other bank is in service.
