A pressure regulator valve including a poppet type valve carried by a plate, which in turn is biased by a diaphragm of considerable area. The diaphragm plate is adjustably spaced closely to the diaphragm chamber cover plate so that movement of the valve sufficient to enable flow, will consume much or all of the clearance, momentarily compressing the gas therein, and dampening valve operation to reduce chatter.
