Manifold valve

From GAWDAwiki

A manifold valve controls the flow of gases and liquids in a manifold .^[1]

A manifold gas valve having a diaphragm valve and an on-off valve controlling gas flow therethrough to a main burner and a pressure regulator valve therein controlling gas flow to a pilot burner. The outlet from the pressure regulators valve communicates with one side of the diaphragm of the diaphragm valve for biasing it open while the other side of the diaphragm responds to main gas outlet pressure to bias the valve closed, whereby a single adjustment of the pilot burner pressure regulator valve provides gas pressure adjustment for both the pilot burner gas and the main burner gas, both of which are controlled by the manifold valve.^[2]
