A valve ( ) for controlling gas flow for a gas heating which allows, as different embodiments, (1) A gradual and smooth transition from high flow to low flow. This is achieved by a rotatable control means ( ) wherein the valve body or control means has a taping groove ( ) on an annular path intersecting with a port to allow variation in flow rate as the control means rotates. (2) The ganging together into modular form of several valve units with the inlet ports forming a common inlet manifold. (3) The control means, at least, is a plastic, eg nylon. (4) The switching to off from either high or low flow is allowed. But the switching from off to on is directly to high flow. The switching from off to on is prevented from going to low flow directly
