Zusammenfassung:	1301354 Fluid-pressure servomotor systems ROBERTSHAW CONTROLS CO 11 May 1970 [12 May 1969] 22729/70 Heading G3P [Also in Division F2] A valve device supplying fuel to a burner 14 comprises a housing 21, 22, 23 containing a pressure regulating valve 29 in series with a pneumatically operated shut-off valve 49. As shown the regulating valve controls the downstream seat 32. The shut-off valve comprises a diaphragm 53 responsive to pressure in a control chamber 52 which is selectively placed in communication with a vacuum source 15 or atmosphere through a control valve 16, the latter being operated thermostatically e.g. by a bimetallic strip, in response to the temperature of the burner.
