Valve Manifolds

Introduction
Valve manifolds are devices utilized for the actuation of opening, closing, balancing, and venting operations of differential pressure transmitters and pressure transmitters, controlling specifications such as fluid pressure, flow, and temperature. MV7000 series valve manifolds consists of shut-off valve, two-valve manifold (column), two-valve manifold, three-valve manifold, and five-valve manifold configurations.

Functions
• Shut-off valve (Code: N)
The function of the shut-off valve is to open or shut off the pipeline flow. During installation, it is crucial to ensure that the flow direction of the applicable medium aligns with the arrow direction marked on the valve body.
• Column two-valve manifold (Code: M)
The column two-valve manifold consists of a shut-off valve (for opening, closing or purging) and a vent valve (typically for debris, water, or air). It is crucial to ensure that the flow direction of the applicable medium aligns with the arrow direction marked on the valve body. The shut-off valve and the vent valve are are distributed at 180°.
• Two-valve manifold (Code: 2)
The column two-valve manifold consists of a shut-off valve (for opening, closing or purging) and a vent valve (typically for debris, water, or air). It is crucial to ensure that the flow direction of the applicable medium aligns with the arrow direction marked on the valve body. The shut-off valve and the vent valve are are distributed at 90°.
• Three-valve manifold (Code: 3)
The three-valve manifold consists of a valve body, two shut-off valves, and a balance valve. Based on the function of each valve in the system, it can be categorized as follows: the positive (upstream) globe valve, the negative (downstream) shut-off valve, and the balance valve located in between. The three-valve manifold is used in conjunction with a differential pressure transmitter to establish or isolate communication between the positive and negative pressure measuring chambers and the impulse point, or to isolate or establish communication between the positive and negative pressure measuring chambers.
• Five-valve manifold (Code: 5)
The five-valve manifold is essentially a three-valve manifold with the addition of vent valves on both the high and low-pressure sides.
